Features Supported by Cisco Unified JTAPI

This chapter describes features supported by the Cisco Unified JTAPI specification.

Account Lockout

The administrator can use the CUCM Admin Panel to configure options for the account lockout.

To configure account lockout options, an administrator can perform either of the following:

  1. Click the Locked by Administrator checkbox in the user credential page.

  2. Set the number of login attempts, which signifies the number of failed logins due to invalid credentials.

  3. Set the maximum idle time (in days) and if the user does not login for that many days, the account is locked.

In case of account lockout, JTAPI delivers detailed exceptions without any warning messages. JTAPI does not allow applications to modify any of these values, it only reports the information.

Backward Compatibility

Agent Greeting

The Agent Greeting feature enables the JTAPI application to instruct the Cisco Unified Communications Manager to automatically play a pre-recorded announcement following a successful media connection to the agent device. The greeting helps to keep the agent sounding fresh as they do not have to repeat common phrases on each call. Agent Greeting is audible for the agent and the customer.

Agent Greeting can be initiated from any phone with a Built-in-Bridge (BIB). A call is initiated from the BIB to the DN specified in the request. Applications are responsible for answering this call and playing the media.

There are two types of calls:

  • A basic call between the customer and agent.

  • A secondary call, known as the Interactive Voice Response (IVR) call, which is created between an IVR device and the BIB of the agent phone.

The application invokes the new Agent Greeting API on a call, which creates an IVR call. The application then answers the call, and is responsible to play a recorded message.

The connection is not created for the agent on the IVR call, and as a result, the applications see the secondary call only. The IVR call has only one connection to play the IVR message.

Regardless of whether or not the application observes the IVR device, the Agent Greeting media plays. Observers on the agent receive an event to start the media. When the media finishes, the application must disconnect the IVR or CTI port that streams the media. When the second call is disconnected, an event is sent to observers on the agent and receives an event to end the media.

This feature is available only on phones that have BIBs. The majority of Cisco Unified IP Phones have BIBs, but the feature may not be available in various older or lower-end phone models. Administrators must enable the BIB for the device and configure it using the Cisco Unified Communications Manager Admin panel.

Whenever a request to addMediaStream is made, JTAPI blocks the request until the IVR device answers the call or CTI responds with a timeout error. Due to this, the JTAPI thread that invoked the addMediaStreamRequest cannot answer its own call, because it is blocked waiting for the request to finish.

Applications intending to use this feature must ensure that one of the following is applicable:

  • The IVR DN is configured to auto-answer incoming calls

  • A separate JTAPI thread or application is set up to answer on the IVR DN

Backward Compatibility

This feature is backward compatible.

  • This is a new feature and has no impact on existing features.

  • There are two new events for this feature, but they are only generated if the application observes the addresses in which the feature is invoked.

  • The odd call model for the IVR call, with only one connection, can have implications for applications that look at the number of connections for any of their logic.

  • Feature interaction is not supported on IVR calls.

    For example, invoking features such as redirect and creating a conference from the IVR call are not supported.

  • The IVR call is intended to stream media. Applications invoke features on the IVR call at their own risk and there are no event flows or call diagrams for any feature interaction on the IVR calls.

AES 256 Algorithm IDs

From release 10.5(2) Cisco Unified Communications Manager now supports the following encryption algorithm IDs:

  • CiscoMediaEncryptionAlgorithmType

  • CiscoMediaEncryptionAlgorithmType.AES_128_COUNTER_80

  • CiscoMediaEncryptionAlgorithmType.F8_128_COUNTER_32

  • CiscoMediaEncryptionAlgorithmType.F8_128_COUNTER_80

  • CiscoMediaEncryptionAlgorithmType.AEAD_128_COUNTER

  • CiscoMediaEncryptionAlgorithmType.AEAD_256_COUNTER

The CiscoMediaEncryptionAlgorithmType.AEAD_128_COUNTER and CiscoMediaEncryptionAlgorithmType.AEAD_256_COUNTER will be negotiated only for a secure call between two SIP endpoints.

CTI ports can register with any of the above algorithms, but will negotiate on AES_128_COUNTER_80 for secure calls.


Note


From Release 12.5(1)SU5 onwards, CTI ports can register with any of the above algorithms for secure calls. For more information, see "Stronger Cipher Suites on CTI Ports" section in Security Guide for Cisco Unified Communications Manager.


Alternate Script Support

Certain IP phone types support an alternate language script other than the default script that corresponds to the phone-configurable locale. For example, the Japanese phone locale has two written scripts. Some phone types support only the default Katakana script, while other phones types support both the default script and the alternate Kanji script. Because applications can send text information to the phone for display purposes, they need to know what alternate script a phone supports, if any.

The new getAltScript() method provides alternate script information for an observed device. Currently there is only one known alternate script: Kanji for the Japanese locale.

JTAPI provides a new method for CiscoTerminal to provide alternate script information.

java.lang.String

getAltScript()

Only one alternate script, Kanji for the Japanese locale, is currently supported. An empty string return value indicates there is no alternate script configured or the terminal does not support an alternate script.

Backward Compatibility

The alternate script feature does not impact JTAPI backward compatibility.

API for Exposing Built-In-Bridge Status

JTAPI exposes the API, CiscoTerminal.isBuiltInBridgeEnabled() to let applications know if the BIB capability is enabled on the terminal or not. Accordingly, the return value is true or false.

This API throws MethodNotSupportedException if it is invoked on a CiscoMediaTerminal or a CiscoRouteTerminal as these devices do not support a BIB.

This API throws InvalidStateException if invoked on a terminal that is not registered with the Cisco Unified Communications Manager.

Interface Changes

Backward Compatibility

This change is backward compatible and does not affect the existing applications.

Arabic and Hebrew Language Support

This version of the Cisco Unified JTAPI supports the Arabic and Hebrew languages, which users may select during installation and in the Cisco Unified JTAPI Preferences user interface.

Backward Compatibility

This feature is backward compatible.

Auto Updater for Linux

In order to support this feature for Linux based JTAPI client machines, auto updater feature has the following changes in its interface. The interface required that applications provide component name, provider IP address, user name and password. Applications do not need to specify an URL for downloading the component. This is done to avoid the issue with updater application in case URL changes between various releases of Cisco Unified Communications Manager Administration.

A new API called "Replace()" is part of the component interface. This facilitates replacing of old component with a newly downloaded component. The following section defines the operation of updater after the new interface changes. The new updater will:

  • Use the same API signature as the old one.

  • Create a file newjtapi.jar in the current folder of application which is the new version of the jar file.

  • Copy the current jtapi.jar to a file by name component.temp in the classpath specified.

  • Replace the current jar file with the new jar file. At the end of this operation, the current jar file becomes the component.temp and new jar file becomes jtapi.jar. Applications can still use old component interface which take URL either by specifying the URL themselves or by querying the URL through the new interface provided on CiscoProvider. The API required to get the URL information is present in the Interface summary for this feature. This operation is supported for both Unix and Windows.

    Backward compatibility

This feature is not backward compatible.

AutoAccept Support for CTI Ports and Route Points

This feature provides applications with the ability to enable or disable AutoAccept for the addresses on CTIPorts and Route Points. When AutoAccept status changes for the address, Cisco Unified JTAPI provides the event to inform the application for changes.


Note


The maximum number of lines that are supported for route points equals 34.


The new interface setAutoAcceptStatus(), provided on the CiscoAddress object, allows the capability to set AutoAccept to ON or OFF. Interface getAutoAcceptStatus(), also provided on the CiscoAddress object, allows applications to query the current status of AutoAccept on the address.

When AutoAccept status changes for the address, applications get CiscoAddrAutoAcceptStatusChangedEv on AddressObservers. This event includes the interface getTerminal(), which returns the terminal on which the AutoAccept status gets changed, and the interface getAutoAcceptStatus(), which returns integers that specify whether AutoAccept is ON or OFF. If an address observer is not added, the event does not get provided.

The following interfaces support AutoAccept on CTIPort and RoutePoint:

Cisco Address

  • init

    init getAutoAcceptStatus (javax.telephony.Terminal terminal)
    

    Ciscoaddress.getAutoAccept(Terminal iterminal) returns an AutoAccept status of address on terminal.

  • void

    setAutoAcceptStatus (int autoAcceptStatus,  javax.telephony.Terminal terminal)

    This allows an application to enable AutoAccept for addresses on the CiscoMediaTerminal and or the CiscoRouteTerminal.

CiscoAddrAutoAcceptStatusChangedEv

CiscoAddrAutoAcceptStatusChangedEv

Public interface: CiscoAddrAutoAcceptStatusChangedEv

Extends com.cisco.jtapi.exension.CiscoAddrEv

The CiscoAddrAutoAcceptStatusChangedEv event gets sent to applications whenever AutoAccept status for the address on the terminal gets changed. If an address has multiple terminals, this event gets sent for the address AutoAccept status on each individual terminal.

This event provides the following interface:
  • init

    getAutoAcceptStatus ()

    CiscoAddrAutoAcceptStatusChangedEv.getAutoAcceptStatus returns the following value of AutoAccept status of address on terminal CiscoAddress.AUTOACCEPT_OFF CiscoAddress.AUTOACCEPT_ON.

  • com.cisco.jtapi.extensions.CiscoTerminal

    getTerminal ()

    Returns the terminal at which this address AutoAccept status gets changed.

For details on the interface changes, see Cisco Unified JTAPI Extensions To view the message flow for AutoAccept on CTIPort and RoutePoint, see Message Sequence Charts

Autoupdate of API

Be aware that when the Cisco Unified Communications Manager is upgraded to a higher version, the APIs may or may not be compatible with the new Cisco Unified Communications Manager version. Ensure that the APIs are upgraded to a compatible version, so the applications work as expected. Because the APIs are installed locally on the client server, the upgrade must take place on multiple machines. In the case of fewer client applications, you can easily do this by connecting to the Cisco Unified Communications Manager Administration and downloading and installing the Cisco Unified Communications Manager compatible plug-in.

For multiple client applications, this feature provides a facility by which an application at startup can identify itself to a web server via an HTTP request and receives a response with the version of the required JTAPI API.

The application compares the version that is available on the server to the local version in the application classpath and determines whether an upgrade is necessary. This allows applications to refresh the jtapi.jar component to match the Cisco Unified Communications Manager and provides a way to centrally deploy the jtapi.jar to which applications can auto update.

The API that is required to perform this functionality gets packaged in the form of an updater.jar. The jtapi.jar and updater.jar get packaged with the standard manifest, which can be used to compare versions.


Note


This feature does not update JTAPI Preferences, JTAPITestTools, Updater.jar and javadoc components. If applications require these components, install JTAPI from the Cisco Unified Communications Manager plug-in pages. Auto Update supports JTAPI Release 2.0 and later.


Refer to Cisco Unified JTAPI Installation for more information.

The following new or changed interfaces exist for autoupdate of APIs:

Class com.cisco.services.updater.ComponentUpdater

Component

queryLocalComponentVersion (java.lang.String componentName, java.lang.String path)

Throws an IOException, IllegalArgumentException.

Component

queryServerComponentVersion (java.lang.String componentName, java.lang.String urlString)

Throws an IOException, IllegalArgumentException, and sends an HTTP query to the server to determine the remote server installed components version.

Interface com.cisco.services.updater.Component

int

compareTo (Component otherComponent)

Component

fetchFromServer ()

Performs an HTTP fetch of the component from the server and writes to the local file system with the file name temp.jar in the local directory.

java.lang.String

getBuildDescription ()

Returns the string 'Release' for a version of the form 'a.b(c.d) Release'.

int

getBuildNumber ()

Returns 'd' for a version of the form a.b(c.d).

java.lang.String

getLocation ()

The string form location of the component.

int

getMajorVersion ()

Returns 'a' version for a version of the form a.b(c.d).

int

getMinorVersion ()

Returns 'b' version for a version of the form a.b(c.d).

java.lang.String

getName ()

Returns the name of the component.

int

getRevisionNumber ()

Returns 'c' for a version of the form a.b(c.d).

The Autoupdater feature in JTAPI also allows applications to download the latest version of JTAPI.JAR directly from the Cisco Unified Communications Manager.

  1. Updater creates a newjtapi.jar file in the current folder of the application, which represents the new version of the jar file that was downloaded from the Cisco Unified Communications Manager.

  2. Updater copies the current jtapi.jar to a file that is named component.temp in the classpath specified.

  3. Updater replaces the current jtapi.jar file with the new jtapi.jar file.

At the end of this operation, the current jar file becomes component.temp and the new jar file becomes jtapi.jar. This operation is supported for both Linux and Windows.

Example Usage of Autoupdater

Command Line : java com.cisco.services.updater.ComponentUpdater <server> <component name> <login> <passwd>Component localComponent,  downloadedComponent;
ComponentUpdater updater  =  new ComponentUpdater();
String localPath  =  updater.getLocalComponentPath(args[1]);
localComponent  =  updater.queryLocalComponentVersion("jtapi.jar",  localPath);
localComponent.copyTo("component.temp");
String provString  =  args[0] + ";login = " + args[2] + ";passwd = " + args[3];

CiscoJtapiPeer peer  =  (CiscoJtapiPeer) (JtapiPeerFactory.getJtapiPeer(null));
CiscoJtapiProperties tempProp  =  ( (CiscoJtapiPeerImpl) (peer)). getJtapiProperties();
tempProp.setLightWeightProvider(true);

Provider provider  =  peer.getProvider(provString);
String url  =  ( (CiscoProvider) (provider)).getJTAPIURL(); provider.shutdown();
Component serverComponent  =  updater.queryServerComponentVersion("jtapi.jar",  url);

downloadedComponent  =  serverComponent.fetchFromServer();
int retVal  =  downloadedComponent.replaces(localComponent);

The "replaces" API will replace the existing JTAPI version with the new version.


Note


The updater will only update the JTAPI.JAR file and not the other sample applications and Cisco JTAPI documentation that are bundled with the JTAPI plug-in. To get these other components, applications must download the plug-in from the Cisco Unified Communications Manager and install it.


Barge and Privacy Event Notification

The Barge Feature provides the ability for shared addresses to barge into an established call of address on another terminal. This feature gets activated when an address TerminalConnection is in the passive state and CallCtlTerminalConnection is in the bridged state. This version of Cisco Unified JTAPI only supports feature activation manually on application-controlled terminals (IP phones). For this release, you cannot activate the feature through an API.

The Privacy feature provides the ability to enable or disable other shared addresses to barge into call. When privacy is enabled, other shared addresses cannot barge into a call and vice versa. Privacy represents a terminals property. IP phones have a "Privacy" softkey and pressing it enables or disables the privacy. Privacy can be dynamically enabled or disabled for the active calls on the terminal. When privacy is on for the call, the TerminalConnection for the call appearances on the shared address appear in the "InUse" state. If privacy status changes during the CallProgress, CiscoTermConnPrivacyChangedEvent gets delivered to the application.

Two types of barge feature functionalities exist in Cisco Unified Communications Manager: one uses built-in conference bridge called "Barge, " while another uses shared conference bridge resources called "CBarge". From the application point of view, no interface changes exists between Barge and CBarge; however, some behavioral changes, which are described in the message flow diagram in Message Sequence Charts occur.

Barge, CBarge, and Privacy have these interfaces:

Interface CiscoTerminalConnection.getPrivacyStatus()

booleangetPrivacyStatus()

This interface returns the privacy status of a call on the terminal.

Interface CiscoTermConnPrivacyChangedEv

javax.telephony.TerminalConnectiongetTerminalConnection()

A new reason code, CiscoCall.CAUSE_BARGE gets added to CiscoCall for barge events.

JTAPI provides CallCtiCause as CiscoCall.CAUSE_BARGE when a SharedLine TerminalConnection or CallCtiTerminalConnection goes to an active or talking state as a result of barge. This cause code also gets provided in CallCtiEvents for dropping temporary calls that are created during the barge operation.

This cause code is not provided for the CBarge scenario.

For details on these interfaces, see Cisco Unified JTAPI Extensions To view the message flow for barge, CBarge, and privacy, see Message Sequence Charts.

Call Control Discovery

The Call Control Discovery (CCD) feature facilitates provisioning for inter-call agent communications. It uses the Service Advertisement Framework (SAF) network service to advertise itself as a call control entity and to discover other call control entities (Cisco Unified Communications Managers or CMEs) on the network so that it can dynamically adapt their routing behavior.

When a call is made between two devices on different clusters and the call is rejected with a cause code other than unallocated , unassigned number and user busy, the CCD feature fails over the call to a PSTN network. That is, the call is routed through a PSTN network instead of an IP network to reach the same destination.

JTAPI supports the SAF CCD feature. However, applications are not notified when a normal SAF call fails over to a PSTN trunk.

JTAPI exposes a new reason CiscoFeatureReason.REASON_SAF_CCD_PSTN_FAILOVER for the new connection created for the redirect or forward destination. This occurs when there is a redirect or forward across the cluster through an SAF trunk and the call fails over to a PSTN trunk.

Interface Changes

See CiscoFeatureReason

Message Sequences

See Call Control Discovery

Backward Compatibility

This feature is backward compatible.

Call Forward

Cisco Unified JTAPI supports setting the Call Forward feature according to the JTAPI Specification. Cisco Unified JTAPI implementation does not support all the forwarding characteristics but supports only the FORWARD_ALL attribute for the Address. Applications can invoke setForwarding, getForwarding, and cancelForwarding methods on a CallControlAddress object, but the CallControlForwarding instruction can only be of type FORWARD_ALL.

Call Forward Override

This feature provides a mechanism to override the call forward all feature. If a user (CFA Initiator) sets CFA to another user (CFA target), the CFA should be ignored if the CFA target calls the CFA initiator. This would allow the CFA Target to reach the CFA Initiator for important calls.

The behavior of this CallManager feature is configurable via service parameter - CFADestinationOverride.

Example: Alice has a phone with DN 1000 * Bob has a phone with DN 2000 * Daniel has a phone with DN 4000 * Alice does a CFA to 2000

CFA behavior * Bob calls Alice. Call goes to Alice and does not follow CFA back to himself. * Daniel calls Alice. Call follows CFA to Bob. * Bob answers and transfers the call to Alice. Bob can do this because Alice has her phone forwarded to Bob. There is no interface change to JTAPI layer with this feature. However JTAPI applications could perceive a difference in behavior when CiscoAddress.setForward() API is invoked. In scenario where CFA target calls the CFA initiator as described in example, call is not forwarded if feature is enabled.

Backward Compatibility

JTAPI applications that were written for Release 5.0 should be backward compatible with Release 5.1. JTAPI Client Upgrade Application does not require JTAPI Client upgrade to run or be backward compatible. JTAPI Client upgrade is required only if new features are used.

Call Park

Cisco Unified JTAPI supports user interactions with Call Park and reports the appropriate events to the applications. When a call is parked from an IP phone, the connection that belongs to the parking address moves into Disconnected state, and the associated TerminalConnection moves into Dropped state. A new connection in queued state for the park number gets created.

If an application is monitoring only the address that parked the call, all existing connections get Disconnected, TerminalConnections get Dropped, and the call moves to Invalid state.

Call Pickup

Call Pickup enables devices to receive alerts within Call Pickup Groups and events, to act on these alerts by invoking APIs that support variants of Call Pickup.

These APIs allow applications to gather information about existing Call Pickup groups, and register and unregister for receiving pickup alerts for specific pickup groups.

JTAPI supports invoking Pickup, Group Pickup, Other Pickup, and Directed Call Pickup from applications. In Cisco Unified Communications Manager releases prior to release 8.0(1), all these features except Other Pickup were supported as observed events, but were not invoked.


Note


Call Pickup is not supported on CTI route points.


Interface Changes

CiscoPickupGroup, CiscoAddress, CiscoTerminal, CiscoProvider, CiscoProviderCapabilities, CiscoProvPickupCallAlertEv, ProviderPickupNotificationRegistrationClosedEv, CiscoAddrPickupGroupChangedEv.

Message Sequences

Call Pickup

Backward Compatibility

This feature is backward compatible.

Call Recording for SIP or TLS Authenticated Calls

Prior to 12.5(1) version, the phones which are authenticated (phone with Security profile having Device Security Mode as Authenticated) were not allowed to make use of the Call Recording feature. Whereas, Non–Secured phones or Secured/ Encrypted phones could use Call Recording feature with Non-Secured or Secured recorders, respectively. With the release 12.5(1), Cisco Unified CM JTAPI interface has been enhanced to allow recording in Authenticated Phones based on the value of the new service parameter Authenticated Phone Recording.

The expectation is that the authenticated phones should also be allowed to make use of the Call Recording feature. It depends on value set in the newly added service parameter Authenticated Phone Recording which can be set to the following values:

  • Allow Recording – Authenticated Phones can be allowed to record the calls.

  • Do Not Allow Recording – Authenticated Phones cannot make use of Call Recording feature. This is the default value for the service parameter. The behavior would be the same as that of the current behavior.

Backward Compatibility

This feature is backward compatible. JTAPI will support the current API’s.

Call Select Status

Cisco Unified JTAPI sends CiscoTermConnSelectChangedEv event whenever the call is selected either by feature or by manually. Once application receives the event, application can use TerminalConnection.getSelectStatus() to get proper call select status. There are three possible statuses by calling TerminalConnection.getSelectStatus() as follows:

  • CiscoTerminalConnection. CISCO_SELECTEDNONE: The select status means that the call is not selected

  • CiscoTerminalConnection. CISCO_SELECTEDLOCAL: The select status means that the call is selected on the terminal connection

  • CiscoTerminalConnection. CISCO_SELECTEDREMOTE: Passive TerminalConnection will get this select status if the call is selected by it's shared line

Backward compatibility

This feature is not backward compatible.

Calling Party Display Name

The CiscoCall interface provides methods to get name displays of the calling party and the called party in a call. Applications can use getCurrentCallingPartyDisplayName() to get the display name of the calling party.

JTAPI applications can use the following interface to get the display names of the calling party and the called party.

{..
..
/**
 *This interface returns the display name of the called party in the call.
 *It returns null if display name is unknown.
*/
public String getCurrentCalledPartyDisplayName();

/**
 *This interface returns the display name of the calling party.
 *It returns null if display name is unknown.
*/
public String getCurrentCallingPartyDisplayName();
}

The address objects store the display name internally, and the name gets updated when currentCallingAddress and currentCalledAddress are updated. NULL returns if the call is not in the active state and if currentCalling and currentCalled addresses of the call are not initialized.


Note


The system does not support Call.getCurrentCalledAddress() and call.getCurrentCallingAddress() for conference calls. Also, the system does not support call.getCurrentCalledPartyDisplayName() and call.getCurrentCallingPartyDisplayName() for a conference call.


Calling Party IP Address

Extensions to CallCtlConnOfferedEv and RouteEvent provide a method for retrieving the IP address of the calling party. This feature provides the calling party IP address to the destination side of basic calls, consultation calls for transfer and conference, and basic redirect and forwarding. The system does not support other scenarios and feature interactions, including those where the calling party changes. This feature only supports IP phones as calling party devices, although IP address of other calling devices may also be provided. See CiscoCallCtlConnOfferedEv and CiscoRouteEvent.

Backward compatibility

This feature is backward compatible.

Calling Party IP Address

The Calling Party IP Address enhancement provides the calling party IP address to the destination side of basic calls, consultation calls for transfer and conference, and basic redirect and forwarding. Only calling party IP phones are supported, although IP address of other calling devices may also be provided.


Note


Other feature interactions are not supported including those during which the calling party changes.


New Cisco extensions to the CallCtlConnOfferedEv and RouteEvent classes are created and expose a method to obtain the calling party IP address. The new extensions are CiscoCallCtlConnOfferedEv and CiscoRouteEvent. An empty returned value indicates that the calling party IP address is not available.

Basic Call scenario

JTAPI application monitors party B

Party A is an IP phone

A calls B

IP Address of A available to JTAPI application monitoring B consultation transfer scenario

JTAPI application monitors party C

Party B is an IP phone

A talks to B

B initiates a consultation transfer call to C

IP Address of B is available to JTAPI application monitoring party C

Consultation conference scenario

JTAPI application monitors party C

Party B is an IP phone

A talks to B

B initiates a consultation conference call to C

IP Address of B is available to JTAPI application monitoring party C

Redirect scenario

JTAPI application monitors party B and party C

Party A is an IP phone

A calls B

IP Address of A is available to JTAPI application monitoring party B

Party A redirects B to party C

Calling IP address is not available to JTAPI application monitoring party B

Calling IP address of B is provided to JTAPI application monitoring party C

Backward compatibility

This feature is backward compatible. Application must invoke a new API to query IP address of a call.

Calling Party Normalization

Calling Party Normalization (CPN) is an enhancement. This feature provides the option to transform or normalize the incoming call number and convert into the E.164 format, which includes the (country code, state code, and number type). The number type field identifies the subscriber, national, international, or unknown. The number type is not supported in conference scenarios.

Interface changes

This feature introduces a new method in CiscoCall that is getGlobalizedCallingParty() and a new method in CiscoPartyInfo that is getNumberType(). See CiscoCall and CiscoPartyInfo for more information.

Message sequences

See Calling Party Normalization

Backward compatibility

This feature is backward compatible.

CallFwdAll Key Press Notification

This feature enables applications to know whether the call is a normal call or a temporary call, when the CallFwdAll key is enabled.

JTAPI exposes this information through the API getCFwdAllKeyPressIndicator() which is exposed on the CiscoCall interface. This API enables the application to know if the call is created due to pressing of CallFwdAll softkey or not. The newly added getCFwdAllKeyPressIndicator()” could return following constants that are also new:

  • If it is pressed on a phone that is in on-hook state to set CallFwdAll, this API returns CiscoCall.CFWD_ALL_SET.

  • If it is pressed on a phone that is in on-hook state to clear the CallFwdAll, this API returns CiscoCall.CFWD_ALL_CLEAR.

  • If the call is made first and then the user presses CallFwdAll key when phone is in off-hook state, this API returns CiscoCall.CFWD_ALL_NONE.

    Interface changes

See CiscoCall

Message Sequences

See CallFwdAll Keys Press Notification

Backward Compatibility

This feature is backward compatible.

CallSelect and UnSelect Event Notification

You can select or unselect call on a phone for doing DirectTransfer or join or any other feature operation. When a SharedLine user selects a call, the RemoteInUse shares line TerminalConection will go passive, and CallCtlTermiCallConnection goes in InUse state. When call is unselected, CallCtlTerminalConnection goes into a bridged state. An application cannot invoke any API on Passive/InUse TerminalConnection. CallProcessing also performs a Select/UnSelect operation during features (such as transfer/conference) operation. Applications will also perceive these events if the applications monitor RemoteInUse terminal.

For example, if A and A' are SharedLine, and A selects the call, CallCtlTerminalConnection of A' goes into a passive or InUse state. If A "UnSelects" the call, the CallCtlTerminalConneciton of A' goes into the passive or bridged state.

To view the message flow for CallSelect or UnSelect, see Message Sequence Charts

Certificate Download API Enhancement

Currently Cisco Unified JTAPI certificate download API has some security issues, to solve the problem, Cisco provides new certificate download APIs. New APIs require applications to specify a certificate pass phrase and the certificate pass phrase is used to encrypt Java key store where client/server certificates are stored.

Old certificate download APIs are deprecated, however, it will still remain for some time to avoid backward compatibility issue for applications. Cisco highly recommends to migrate the application to new APIs.

Cisco Unified JTAPI also provides new API deleteCertificate() and deleteSecurityPropertyForInstance() that can be used by application to delete certificates already installed. To change pass phrase for certificate java key store, the application must delete the old certificate by using this API and upload new certificate.

JTAPIPreferences UI security tab enhancement provides two new buttons, one for DeleteCertificate and another for Update Certificate. DeleteCertificate button allows users to delete the certificate for required username/instanceID. Update Certificate button allows users to upload the certificate from CAPF server. If certificate update is successful, certificate update box is updated to show Updated; authorization string and certificate pass phrase are cleared. If certificate update operation fails, certificate box continues to show status Not Updated status unless certificate was previously updated. User/Applications must provide certificate pass phrase every time they try to update certificate, Cisco Unified JTAPI does not save certificate pass phrase for security reason in any circumstances. Applications own the responsibility to secure the pass phrase and provide it through API when needed.

Backward Compatibility

This feature is backward compatible.

Changes in DeviceType Name Handling

Currently, TSP hardcodes the DeviceTypeName depending on the DeviceType. When a new device type is added, we have to manually add the new device type name to the list of supported devices. Because CTI does not fetch and store the device type name in its cache, TSP cannot get this info from CTI. TSP needs to update the device type name when a new device type is added without any manual intervention.

In JTAPI, the changes have been made to ensure that QBE interface changes to handle the receive devicetypename that is sent from CTI and is stored in the deviceInfo structure. It is not used anywhere in JTAPI and will not be exposed to applications. Only the QBE interface changed as follows:

public DeviceRegisteredEvent ( String ride,  int deviceType,  boolean allowsRegistration,  int deviceID,  boolean loginAllowed,  UnicodeString userID,  boolean controlled,  int reasonInt,  int registrationType,  int unicodeEnabled,  int locale, 
// added for deviceTypeName change 
String devTypeName) {
public DeviceUnregisteredEvent ( String deviceName,  int deviceType,  boolean allowsRegistration,  int deviceID,  UnicodeString userID,  boolean controllableBool,  int reasonInt ,  int locale, 
//added for devtypename support
String devTypeName) {

Cisco MediaTerminal

In JTAPI, the terminal object represents the logical endpoint for a call and is presumed to be able to receive and transmit data (digital encoded voice samples, for example). Thus, terminals in JTAPI represent Cisco Unified IPPhones. Even though gateways terminate media, terminals do not represent them. The CiscoMediaTerminals in particular represent a special kind of endpoint for which applications take responsibility for media termination.

The following four steps associate with using CiscoMediaTerminals:

  • Provisioning

  • Registration

  • Adding Observers

  • Accepting Calls

Provisioning

Ensure CiscoMediaTerminals, which are analogous to physical terminals, get provisioned accordingly in Cisco Unified Communications Manager, even though they do not represent actual hardware IP phones or gateways. Just as IP phones must be added to Cisco Unified Communications Manager database by using the Device Wizard, CiscoMediaTerminals get added the same way, so Cisco Unified Communications Manager can associate the application endpoint with a directory number and other call control properties such as call forwarding. No device type called CiscoMediaTerminal exists in the DeviceWizard. Instead, Cisco Unified Communications Manager has one or more device types that support application registration—each of these types get exposed as a CiscoMediaTerminal through JTAPI. Currently, only the device type CTI port represents a CiscoMediaTerminal in JTAPI.

This procedure lists the steps for provisioning a CTI port for use as an application-controlled endpoint.

  1. Within the Cisco Unified Communications Manager configuration windows, add a CTI port device from the Device-Phone window by using the Device Wizard. The CTI port device name specifies the name of the corresponding CiscoMediaTerminal in JTAPI.

  2. Add the new CTI port device, by using the User-Global Directory window, to the list of devices that the application controls by using the User window.

For more information, refer to the Cisco Unified Communications Manager Administration Guide.

Registration

After a media termination device is properly provisioned in Cisco Unified Communications Manager, the application may obtain a reference to the corresponding CiscoMediaTerminal object by using either the Provider.getTerminal() method or CiscoProvider.getMediaTerminal() method. The two methods differ in that the CiscoProvider.getMediaTerminal() method only returns CiscoMediaTerminals, whereas Provider.getTerminal() will return any terminal object that is associated with the provider, including those representing physical IP phones.

Use the CiscoMediaTerminal.register() method to notify Cisco Unified Communications Manager of the intent to terminate RTP streams of certain payload types. The CiscoMediaTermina.register() method takes an IP address, a port number, and an array of CiscoMediaCapability objects that indicate the types of codecs that the application supports as well as codec-specific parameters.

The IP address and port indicate the address where the application can receive media streams. The following sample code demonstrates how to register a CiscoMediaTerminal and bind it to a local address, port number 1234:

CiscoMediaTerminal registerTerminal (Provider provider,  String terminalName) {  final int PORT_NUMBER  =  1234;
  try {
   CiscoMediaTerminal terminal  =  provider.getTerminal (terminalName);
   CiscoMediaCapability [] caps  =  new CiscoMediaCapability [1];
   caps[0]  =  CiscoMediaCapability.G711_64K_30_MILLISECONDS;
   terminal.register (InetAddress.getLocalHost (),  PORT_NUMBER,  caps);
  }
  catch (Exception e) {
    return null;
  }
}

For this sample code to work, ensure the specified provider is IN_SERVICE. Further, be aware that this code uses the constant CiscoMediaCapability.G711_64K_30_MILLISECONDS. This actually represents a static reference to a CiscoG711MediaCapability object that specifies a 30-millisecond maximum RTP packet size. The CiscoMediaCapability class predefines this and other common media formats.

To specify a media payload that is not listed in the CiscoMediaCapability class, two options exist. If the desired payload type is a simple variation of one of the existing subclasses of CiscoMediaCapability, you only need to construct a new instance of the subclass. For instance, if an application can support G.711 payloads with a 60-millisecond maximum RTP packet size, it can construct the CiscoG711MediaCapability object directly; including specifying 60 milliseconds in the constructor.

Alternatively, if no existing subclass of CiscoMediaCapability that matches the desired payload type exists, construct an instance of the CiscoMediaCapability class directly. The maximum packet size, for example, 30-milliseconds, represents the only other parameter that may be specified when a CiscoMediaCapability is constructed.

The following code illustrates registering a custom payload capability:

CiscoMediaTerminal registerTerminal (Provider provider,  String terminalName) {  final int PORT_NUMBER  =  1234;
  try {
   CiscoMediaTerminal terminal  =  provider.getTerminal (terminalName);
   CiscoMediaCapability [] caps  =  new CiscoMediaCapability [1];
   caps[0]  =  new CiscoMediaCapability (
     RTPPayload.G728, 
     30  // maximum packet size,  in milliseconds
     );
   terminal.register (InetAddress.getLocalHost (),  PORT_NUMBER,  caps);
  }
  catch ( Exception e) {
    return null;
  }
}

The payload type parameter that is used for constructing the CiscoMediaCapability object corresponds to the payload field in the RTP header. The RTPPayload interface defines a number of well-known payload types for this purpose.

Adding Observers

To receive events that indicate where and when to transmit and receive RTP data, place a CiscoTerminalObserver on the CiscoMediaTerminal. The CiscoTerminalObserver extends the standard JTAPI TerminalObserver interface without defining any new methods; it provides a marker interface that signals the application interest in receiving RTP events.


Note


Because this is a TerminalObserver, not a CallObserver, it must get added by using the Terminal.addObserver() method, not the Terminal.addCallObserver() method.


Additionally, add a CallControlCallObserver to the Address object that is associated with the CiscoMediaTerminal. This guarantees that the application will get notified when calls are offered to the CiscoMediaTerminal. Unlike regular IP phones, which automatically accept any offered call, CiscoMediaTerminals accept, disconnect (reject), or redirect any call that is offered to it. Because the CallCtlConnOfferedEv only gets presented to CallControlCallObservers that are placed on Address objects, not Terminal objects, the application places its CallControlCallObserver in the correct place.


Note


Be sure to implement the CallControlCallObserver interface, not just the CallObserver interface; the CallCtlConnOfferedEv will not get delivered to observers that implement only the core CallObserver interface.


Accepting Calls

When an inbound call arrives at the CiscoMediaTerminal address, it must be accepted by using the CallControlConnection.accept() method before a terminal connection gets created. This process does not apply for outbound calls —the connection will occur in the CallControlConnection.ESTABLISHED state as soon as the call progresses beyond digit recognition. After the connection is accepted, answer the ringing terminal connection to start media flow. Assuming that Cisco Unified Communications Manager can match the capabilities that were registered with the capabilities of the calling endpoint, Cisco Unified Communications Manager sends the Media Flow events, so the application can begin transmitting and receiving RTP data.

Cisco Unified Communications Manager Media Endpoint Model

Endpoints represent the entities within the Cisco Unified Communications Solutions platform that terminate media, such as IP telephones and gateways. A call from one endpoint to another results in media flowing between the two endpoints. All endpoints in the Cisco Unified Communications Solutions platform transmit voice data by using real-time protocol (RTP). The Cisco Unified Communications Solutions telephones and gateways, for example, include built-in RTP stacks. Applications may also act as endpoints in a Cisco Unified Communications Solutions system; that is, they may terminate media. Because all Cisco Unified Communications Solutions endpoints use RTP, applications also must be able to transmit and receive RTP packets.

Payload and Parameter Negotiation

In addition to bearer data and payload, each RTP packet contains a header that helps endpoints to determine how to reassemble and decode a sequence of such packets into a media stream. RTP does not provide, however, a means for endpoints to negotiate which payload type to use for a particular stream: for example, audio data that is encoded by using the G.711 standard. Furthermore, RTP does not offer a means of negotiating unique payload type parameters such as the sampling rate of the encoded data or the number of samples that are to be transferred in each RTP packet. Instead, RTP usually gets used in conjunction with another protocol such as H.323, which specifies its own method for endpoints to negotiate these parameters. All such negotiation occurs prior to transmitting RTP packets between endpoints.

Cisco Unified Communications Manager, not the endpoints, has responsibility for selecting the payload and encoding parameters for RTP streams. The following five steps that are involved in a typical bidirectional audio telephone call apply:

  • Initialization

  • Payload Selection

  • Receive Channel Allocation

  • Starting Transmission and Reception

  • Stopping Transmission and Reception

Initialization

Upon startup, each endpoint informs Cisco Unified Communications Manager of its media capabilities, that is, G.711, G.723, G.729a, and so on. Startup for an IP phone, for example, occurs when the phone is first turned on, or after it recontacts Cisco Unified Communications Manager after losing its former connection. The endpoint cannot express a preference for one payload type versus another, but it can specify certain parameters for each payload type, such as, packet size.

The capability list that the endpoint registers remains exclusive and immutable. If the endpoint specifies that it can support both G.711 and G.723, it implicitly declares that it cannot support G.729a. Moreover, the endpoint must disconnect from Cisco Unified Communications Manager and reinitialize to change the list of capabilities that it supports.

JTAPI applications perform this step by registering a CiscoMediaTerminal with Cisco Unified Communications Manager. The CiscoMediaTerminal.register() method allows applications to supply an array of media capability objects for registration with Cisco Unified Communications Manager. This step informs Cisco Unified Communications Manager that the application will act as the endpoint for all calls to or from a particular directory number, as determined by the device configuration in the Cisco Unified Communications Manager configuration.

Payload Selection

When a bidirectional media stream is about to be created between two endpoints, for instance, when a call is answered at an endpoint, Cisco Unified Communications Manager selects an appropriate payload type (codec) for the media stream. Cisco Unified Communications Manager compares the media capabilities of both endpoints that are involved in the call and selects the appropriate common payload type and payload parameters to use.

The basis for payload selection includes endpoint capabilities and location, although other criteria may get added to this selection logic in the future. Endpoints do not get dynamically involved in selecting payload types on a call-by-call basis.

Receive Channel Allocation

If Cisco Unified Communications Manager can find a common payload type for the RTP stream between the two endpoints, it requests that each endpoint create a logical "receive channel"; that is, a unique IP address and port at which the endpoint will receive RTP data for the call. Each endpoint returns an IP address and port to Cisco Unified Communications Manager in response to this request.

Currently, only IP phones and gateways perform this step. Cisco Unified Communications Manager requires JTAPI applications to specify a fixed IP address and port during initialization. Therefore, JTAPI applications cannot terminate more than one media stream simultaneously for the same endpoint. Applications that want to terminate multiple media streams must register multiple endpoints simultaneously.

If the endpoint does not respond to the open receive channel request quickly enough, Cisco Unified Communications Manager disconnects the call. Because JTAPI applications always supply an IP address when CiscoMediaTerminals are registered, calls to application-controlled endpoints do not get disconnected for this reason. However, if Cisco Unified Communications Manager cannot find a common payload type between the two endpoints that are involved in the call, Cisco Unified Communications Manager disconnects the call.

Starting Transmission and Reception

After Cisco Unified Communications Manager receives channel information for both parties, it informs each endpoint of the codec parameters that it selected for the RTP stream and the destination address for the other endpoint. This information gets conveyed in two messages to each endpoint: a start transmission message and a start reception message.

JTAPI applications receive the CiscoRTPOutputStartedEv and CiscoRTPInputStartedEv events that contain all the codec parameters that are necessary for sending and receiving RTP data.

As a part of the QoS baselining effort in JTAPI, CiscoRTPOutputStartedEv provides the getPrecedenceValue() API to applications. CTI presents this value, The DSCP for Audio Calls to JTAPI. Using this value, applications can set the DSCP value for the media streams that they open.

Stopping Transmission and Reception

When the RTP stream must get interrupted because of a feature such as hold or disconnect, Cisco Unified Communications Manager requests that each endpoint stop its transmission and reception of RTP data. Just as when the media flow is started, the stop transmission and stop reception messages get sent separately.

JTAPI applications receive the CiscoRTPOutputStoppedEv and CiscoRTPInputStoppedEv.

Cisco Unified Communications Manager Server Failure

If a Cisco Unified Communications Manager server fails, the associated devices re-home to the next Cisco Unified Communications Manager server in the group. The prioritized list of Cisco Unified Communications Managers in the device pool information configuration for each device defines this process.

Failure of a Cisco Unified Communications Manager server only results in a partial outage of devices in the cluster. Those devices remain available following a successful Cisco Unified Communications Manager failover and registration with a secondary Cisco Unified Communications Manager.


Note


A device such as a Cisco Unified IPPhone 7960 fails over to a secondary Cisco Unified Communications Manager server only when no active calls exist on that device. The failure of a Cisco Unified Communications Manager server during a call results only in termination of observation of that device. The media path continues to exist but without any further call control features.


Cisco Unified JTAPI communicates this partial outage to applications by using CiscoAddrOutOfServiceEv and CiscoTermOutOfServiceEv events. When the Cisco Unified Communications Manager fails over, the device must successfully register to the secondary Cisco Unified Communications Manager before the device is available to the JTAPI applications. Cisco Unified JTAPI will send the CiscoAddrInServiceEv and CiscoTermInServiceEv events.

The Provider remains in service during this time. Devices on other Cisco Unified Communications Manager servers remain available for call control. The events get sent on callbacks of the respective Address or Terminal observer objects. CiscoAddrOutOfServiceEv and CiscoAddrInServiceEv events get sent to an object that is implementing the AddressObserver and get added to an Address by using the addressChangedEvent() callback object method. The CiscoTermOutOfServiceEv and CiscoTermInServiceEv events get sent to an object that is implementing the TerminalObserver interface and get added to a Terminal that is using the terminalChangedEvent() callback method.

If the devices are currently in a call, a CallObservationEnded message is sent on the CallObserver callChangedEvent() callback, followed by the CiscoAddrOutOfServiceEv and CiscoTermOutOfServiceEv messages.


Note


Applications must monitor for and respond to the CiscoAddrOutOfServiceEv, CiscoTermOutOfServiceEv, CiscoAddrInServiceEv, and CiscoTermInServiceEv events before the calling call control functions on the address or terminal. Applications that do not support this action may encounter unexpected errors because the applications do not know the exact state of the system.


Cisco Unified IP 7931G Phone Interaction

You can configure Cisco Unified IP 7931G phones in two modes:

  • NoRollOver

  • RollOver (across the same DN or across different DNs)

When Cisco Unified IP 7931G phones are configured in NoRollOver mode, they operate like regular phones that are running SCCP, and in this mode transfers or conferences cannot occur across the different addresses. JTAPI will support controlling and monitoring of a 7931G phone when it is configured in NoRollOver mode.

In RollOver mode, Cisco Unified IP 7931G phones support transfer or conference across different addresses. In this mode, JTAPI does not allow controlling and monitoring of a Cisco Unified IP 7931G phone. Applications see such terminal/addresses as restricted. If a Cisco Unified IP 7931G phone is in the control list of an application user and the phone configuration changes from NoRollOver to RollOver mode, JTAPI sends a CiscoAddrRestrictedEv event for addresses on the Cisco Unified IP 7931G phone and sends a CiscoTermRestrictedEv for terminals, with cause CiscoRestrictedEv.CAUSE_UNSUPPORTED_DEVICE_CONFIGURATION.

However, if the phone configuration changes from RollOver to NoRollOver mode, JTAPI sends a CiscoAddrActivatedEv event for addresses on the Cisco Unified IP 7931G phone and sends a CiscoTermActivatedEv for terminals.

If a Cisco Unified IP 7931G phone that is configured in RollOver mode transfers or conferences to JTAPI-controlled addresses, JTAPI applications do not recognize a common controller in the final and the consult call. This would provide different behavior to the JTAPI application. Depending on how the JTAPI application is processing information that is provided in events, applications may require changes to handle JTAPI events for this transfer or conference scenario.

You can disable transfers and conferences across the line by configuring the Cisco Unified IP 7931G phone to NoRollOver mode through the phone configuration window of Cisco Unified Communications Manager Administration.

There are two new cause codes for the CiscoRestrictedEv interface. When the terminal or address is restricted because a Cisco Unified IP 7931G phone is configured in RollOverMode, JTAPI sends CiscoAddrRestrictedEv with cause CiscoRestrictedEv.UNSUPPORTED_DEVICE_CONFIGURATION. This release also introduces a default cause code CAUSE_UNKNOWN, which applications should handle.

Backward Compatibility

This feature is backward compatible. You can disable this feature by configuring all Cisco Unified IP 7931G phones in a cluster in NoRollOver mode or by not having any Cisco Unified IP 7931G phones in a Cisco Unified Communications Manager cluster. If any phone in a Cisco Unified Communications Manager cluster is configured with RollOver mode, it may cause changes to the behavior of JTAPI-controlled addresses and terminals.

For more information, see CiscoRestrictedEv.

Cisco Unified JTAPI Install Internationalization

Cisco Unified JTAPI supports multiple languages for the JTAPI installation and user preference UI. When JTAPI launches, you receive options for choosing languages for the installation. After choosing a language, further installation instructions display in the chosen language. The first option always specifies English. If certain phrases are missing in the locale language, the instructions default to English. See Cisco Unified JTAPI Installation for more information.

Cisco VG248 and ATA 186 Analog Phone Gateways

Cisco Unified JTAPI supports control of analog phones that are connected to the Cisco VG248 and ATA 186 Analog Phone Gateways. By adding the Cisco VG248 and ATA 186 Analog Phone Gateways to the user-controlled list, applications can control the devices.

Applications receive events for the devices in a way similar to other IP phones. Applications can also initiate calls and invoke other features except answer Request through APIs. Make call works only when the device goes physically off hook.

Applications cannot answer calls from APIs for the devices. If an application attempts to answer () on TerminalConnection for the VG248 and ATA 186 Terminal, the system throws PlatformException with error CiscoJtapiException.COMMAND_NOT_IMPLEMENTED_ON_DEVICE. To answer calls, you must manually pick up the handset, and then you can invoke other call control features such as transfer, conference, blind transfer, and park from the API.

CiscoJtapiExceptions

Cisco Unified JTAPI notifies the application of CTI-generated error codes. These codes return when an exception or error occurs in the CTIManager. The CTI returned error code propagates to the application separately. The application can extract the error code by invoking getErrorCode() method on the exception object, can get CTI error code name by invoking getErrorName() method, and can get error description by invoking method getErrorDescription().

The methods getErrorName(int errorCode) and getErrorDescription (int errorCode) deprecate and get removed in future releases. Cisco recommends that application users do not use these methods.

CiscoJtapiExceptions interface defines error codes in JTAPI.

When a PlatformException is thrown, it can be queried to get the error code, which can be compared to the following.

Errors

Problem Error Message CTIERR_LOGIN_FAILED_PWD_EXPIRED_USER_CAN_RESET

Possible Cause This value is a static definition that identifies an error code as a login failure due to an expired password. In addition, this error code lets the application know that the user can change their password.

Solution  Try resetting the password.

Problem Error Message CTIERR_LOGIN_FAILED_PWD_EXPIRED_USER_CANNOT_RESET

Possible Cause Explanation This value is a static definition that identifies an error code as a login failure due to an expired password. In addition, this error code lets the application know that the user cannot change their password, and that an administrator will have to reactivate the account.

Solution Contact the administrator to reactivate the account.

Problem Error Message CTIERR_LOGIN_FAILED_ACCOUNT_LOCKED

Possible Cause This value is a static definition that identifies an error code as a login failure due to the user account being locked. This is a generic exception for the various types of account lockout. The applications are not informed the reason for the account lockout.

Solution Contact the administrator to unlock the account.

Problem Error Message CTIERR_RECORDING_INVOCATION_TYPE_NOT_MATCHING

Possible Cause This error code is returned when an application invokes a stopRecording() request and passes a method of recording other than the method that was specified when the recording was started.

Problem Error Message CTIERR_INVALID_REMOTE_DESTINATION_NUMBER

Possible Cause This error code is returned when an invalid remote destination number is enterred.

Problem Error Message CTIERR_DUPLICATE_REMOTE_DESTINATION_NUMBER

Possible Cause This error code is returned when the same remote destination number is entered twice.

Problem Error Message CTIERR_REMOTEDESTINATION_LIMIT_EXCEEDED

Possible Cause This error code is returned when the number of remote destinations has exceeded the max number limit.

Problem Error Message CTIERR_REMOTE_DEVICE_REQUEST_FAILED_ACTIVE_RD_NOT_SET

Possible Cause This error code is returned when the active remote destination is not set.

Problem Error Message CTIERR_ENDUSER_NOT_ASSOCIATED_WITH_DEVICE

Possible Cause This error code is returned when the enduser is not associated with the device.

Problem Error Message CTIERR_DEVICE_ALREADY_REGISTERED_NONEXTEND

Possible Cause This error code is returned when the device registration failed due to the device already being registered in non-extend mode.

Problem Error Message CTIERR_MEDIA_ALREADY_TERMINATED_EXTEND

Possible Cause This error code is returned when the device registration failed due to the device already being registered in extend mode.

Problem Error Message CTIERR_INVALID_REMOTE_DESTINATION_NAME

Possible Cause This error code is returned when an invalid remote destination name is entered.

CiscoProvAuthenticationInfoEv

CiscoProvAuthenticationInfoEv code returns to notify the application that the password is about to expire or has already expired. The application should have Provider Observer onto the Provider object to receive this event.

If the application invokes a connection and it fails because of an expired password, it will receive a PlatformException with a newly defined error code. For more information, see CiscoJtapiExceptions.

In the case of a failover, the application will not explicitly request a connection, and will not receive a PlatformException. As the provider will already have an observer, it will deliver a CiscoProvAuthenticationInfoEv to it with getDaysUntilPasswordExpiry() = CiscoProvAuthenticationInfoEv.PASSWORD_EXPIRED.

CiscoRTPHandle Interface on Cisco RTP Events

The following interfaces are enhanced to allow applications to get a CiscoRTPHandle from the events:

CiscoRTPHandle represents the callID of the call in Cisco Unified Communications Manager and stays the same as long as the call is active on the terminal. At any particular terminal/address, although the call and the associated GCID can change, CiscoRTPHandle will remain constant.

Cisco Terminal Filter and ButtonPressedEvents

Prior to the JTAPI 2.0 release, Cisco Unified JTAPI applications did not have direct control over terminal events. Applications can now receive button pressed events by setting the appropriate filter in the terminal observer. Applications no longer need to add call observer to get RTP events.

When setButtonPressedEv gets enabled by using CiscoTermEvFilter, applications receive CiscoTermButtonPressedEv when a digit gets pressed on the phone.

The following new or changed interfaces exist for CiscoTerminal Filter and ButtonPressedEvents:

CiscoTerminal

void

setFilter (CiscoTermEvFilter terminalEvFilter)

Allows an application to have more control over the events thatget delivered to the TerminalObserver.

CiscoTermEvFilter

boolean

getButtonPressedEnabled()

Gets the enable or disable status of the button-pressed events for the terminal. The default value specifies disabled.

boolean

getDeviceDataEnabled()

Gets the enable or disable status of the device data events for the terminal. The default value specifies disabled.

boolean

getRTPEventsEnabled()

Gets the enable or disable status of the RTP events for the terminal. Thedefault value specifies disabled.

void

setButtonPressedEnabled (boolean enabled)

Enables or disables the button pressed events for the terminal.

void

setDeviceDataEnabled (boolean enabled)

Enables or disables the device data status events for the terminal.

void

setRTPEventsEnabled (boolean enabled)

Enables or disables the RTP events for the terminal.

CiscoTermButtonPressedEv

int

getButtonPressed ()

For details on the interface changes, see Cisco Unified JTAPI Extensions To view the message flow for CiscoTerminal Filter and ButtonPressedEvents, see Message Sequence Charts

CiscoTermRegistrationfailed Event

This event gets provided to the application when CiscoMediaTerminal or CiscoRouteTerminal registration fails asynchronously. Usually when registration fails, the application gets a CiscoRegistrationFailedException; however, it is possible that the registration request was successful, but the CTI rejected the registration. This event is provided for the cases where the registration request is successful, but the registration gets rejected. The application should have TerminalObserver to receive this event. Upon receipt of this event, the applications should reregister with the new parameter, depending on the error code that is provided for this event.

The following list provides the errors that get returned and the actions to take, by the application, to resolve them.

Errors

Problem Error Message CiscoTermRegistrationFailedEv.MEDIA_CAPABILITY_MISMATCH

Possible Cause Registration cannot get done because the terminal is already registered. Do the second registration with the same media capability.

Solution Try re-registering with the same capability.

Problem Error Message CiscoTermRegistrationFailedEv.MEDIA_ALREADY_TERMINATED_NONE

Possible Cause Registration cannot get done because the terminal is already registered with media termination type 'none'.

Solution Try re-registering with media termination type 'none'.

Problem Error Message CiscoTermRegistrationFailedEv.MEDIA_ALREADY_TERMINATED_STATIC

Possible Cause Registration cannot get done because the terminal is already registered with static media termination. For static registration, the second registration is not allowed.

Solution Wait until the terminal UnRegisters.

Problem Error Message CiscoTermRegistrationFailedEv.MEDIA_ALREADY_TERMINATED_DYNAMIC

Possible Cause Registration cannot get done because the terminal is already registered with dynamic media termination.

Solution Try re-registering with dynamic media termination.

Problem Error Message CiscoTermRegistrationFailedEv.OWNER_NOT_ALIVE

Possible Cause When trying to register the terminal, registration gets in a race condition.

Solution Try re-registering the terminal.

The following interface is defined for this event:

int getErrorCode () //

Returns the errorCode for this exception

No changes exist in the message flow.

Cius Persistency

Wireless devices introduced by Cisco, for example the Cisco Cius, have the capability to move between WiFi networks and still retain their registration to a single CiscoUCM. However, due to the change in the network the IP address of the device might undergo a change.To indicate this change in IP address of wireless devices like Cius, Cisco JTAPI will expose a new interface to applications with the 9.0.1 release.

The new provider event - CiscoProvTerminalIPAddressChangedEv, will indicate that the IP address of the terminal has changed. Applications may choose to ignore this new event if they do not plan to support a Cius device.

On receiving this event, applications can query for the changed IP address of the terminal using the methods exposed in the new event or on the CiscoTerminal. This interface will also expose the IP addressing mode of the terminal, based on which IPv4/IPv6 address of the terminal can be queried.

Sample Code

public synchronized void providerChangedEvent( ProvEv[] eventList )
{
  try
  {
    for ( int i  =  0; i < eventList.length; i++ )
    {
    case (eventList[i].getID()) ){
        switch:
CiscoProvTerminalIPAddressChangedEv.ID:
      Terminal term  =  eventList[i]
                        .getTerminal();
        int ipAddrMode  =  eventList[i].getIPAddressingMode();
        InetAddr ipV4Addr  =  null;
        InetAddr ipV6Addr  =  null;
        if(ipAddrMode  =  CiscoTerminal.IP_ADDRESSING_MODE_IPv4)
        {
          ipV4Addr  =  eventList[i].getIPv4Address();
        }
        else if(ipAddrMode  =  CiscoTerminal.IP_ADDRESSING_MODE_IPv6)
        {
          ipV6Addr  =  eventList[i].getIPV6Address();
        }
        System.out.println(" TerminalName  = " + term.getName()  + 
           " ipAddressing Mode  = " + ipAddrMode +
           " IPv4 Address  = " + ipV4Addr +
           " IPv6 Address = " + ipV6Address);
      }
    }
    catch (exception e)
    {
      …
    }
  }

Backward Compatibility

Clear Calls

Cisco Unified JTAPI applications can clear phantom calls without dropping active calls. The CiscoAddress provides a clearCallConnections message to allow applications to clear the calls when no active calls exist on the Cisco Unified Communications Manager (formerly Cisco Unified Call Manager).

Click to Conference

Click to conference feature provides interfaces on SIP trunk for applications such as Instant Messenger (IM) to add parties to a conference. Users can add other parties to a conference or remove parties by using such applications. When click to conference is used to add a party to conference, a call is offered to the target address. Only one connection for target address is created on this initial call. This call then gets added to conference which results in a new callID for the call on the target address and connections for other addresses in the call are created on the new call.

This section describes the interface changes in Cisco Unified JTAPI to handle the interactions when an address is added to a conference by using click to conference feature. When click to conference feature is used, consult call does not occur and Cisco Unified JTAPI applications do not receive CiscoConferenceStartEv or CiscoConferenceEndEv.

The feature can be disabled by turning off the "ENABLE CLICK TO CONFERENCE" CallManager service parameter.

Backward Compatibility

Cluster Abstraction

The CTIManager provides a virtual representation of all the Cisco Unified Communications Managers in a cluster. Cisco Unified JTAPI applications communicate with the CTIManager instead of with a specific Cisco Unified Communications Managers. The CTIManager also maintains connection between Cisco Unified Communications Managers in a cluster. This allows a provider to represent any devices in the cluster under the CTIManager. Single-Box Configuration with JTAPI, Cisco Unified Communications Manager, and CTIManager in One Box illustrates “Single-Box Configuration with JTAPI, Cisco Unified Communications Manager, and CTIManager in One Box.” Redundant Cisco Unified Communications Manager and CTIManagers with JTAPI Deployed as a Separate Client illustrates “Redundant Cisco Unified Communications Manager and CTIManagers with JTAPI Deployed as a Separate Client.”

For more details about the cluster administration and device pool settings, refer to the Cisco Unified Communications Manager help information.

Figure 2. Redundant Cisco Unified Communications Manager and CTIManagers with JTAPI Deployed as a Separate Client



Note


In previous releases of Cisco Unified Communications Manager, applications that are running on Cisco Unified JTAPI could only control or monitor devices that are registered under a single Cisco Unified Communications Manager. If a Cisco Unified Communications Manager server went down, the connection between the Cisco Unified Communications Manager server and JTAPI would terminate and the Provider would shut down.


Command Line Invocation

This mode helps to install JTAPI in systems that do not have GUI support (for example, a Linux account). The entire installation procedure is guided by a character input based menu, where the user is asked to provide a series of inputs, based on the install time conditions. This mode also provides all the other options provided by the GUI based installer.

Component Updater

The Component Updater interface is enhanced to allow applications to specify the location of updater log. Currently the updater log is created in the same directory as the application. This enhancement allows applications to specify the trace location.

Interface Changes

Message Sequences

Backward Compatibility

This feature is backward compatible.

Conference

When you conference two calls together, JTAPI specifies that all the parties from one call be moved to the other call. The call whose parties are moved away and that subsequently becomes invalid gets identified as the “merged” or “consult” call. The call to which the merged parties move gets identified as the “final” call hereafter. When parties move from the merged call to the final call, the application receives events that indicate that all parties dropped from the merged call and events that indicate that the parties reappeared on the final call.

To correlate the newly created connection objects with the old connection objects, use the CiscoConection.getConnectionID() method to obtain CiscoConnectionID objects for all old connections and all new connections. Matching connections will have identical CiscoConnectionID objects when you compare them by using the CiscoConnectionID.equals() method.

Conference support exists for the following methods:

  • javax.telephony.callcontrol.CallControlCall.conference(Call)

  • javax.telephony.callcontrol.CallControlCall.getConferenceController()

  • javax.telephony.callcontrol.CallControlCall.getConferenceEnable()

  • javax.telephony.callcontrol.CallControlCall.setConferenceController(TerminalConnection)

  • javax.telephony.callcontrol.CallControlCall.setConferenceEnable(boolean)


Note


As of Cisco Unified Communications Manager Release 8.6, Cisco TelePresence MCU conference bridges are supported through JTAPI/TSP. From a JTAPI/TSP perspective, this conference bridge behaves in the same way as other supported conference bridges.


Cisco Extensions

Cisco Unified JTAPI implementation provides two extra events that signal the Start and End of Conference: CiscoConferenceStartEv and CiscoConferenceEndEv. These events get sent when Conference initiates and when it completes. They give handles to the final call, the merged conference (consult) call, and the two controlling TerminalConnections (in HELD and TALKING state).

CiscoConferenceStartEv

This event gets sent when call1.conference(call2) is invoked or if the Conference button is pressed for the second time on an IPphone. The ConferenceStartEv signifies the start of the merging process. A sequence of merging events that are reflected by the Conference process in Cisco Unified Communications Manager follows.

CiscoConferenceEndEv

This event gets sent at the end of the merge process after a ConferenceStartEv is sent. It signifies the completion of the merge of the Consult (or Merged) call into the Final Conference Call. The Merged call specifies an INVALID state, and an ObservationEndedEv gets sent for the call observer.

CiscoCall.setConferenceEnable()

The Cisco Unified JTAPI implementation uses the CiscoCall.setConferenceEnable() and the CiscoCall.setTransferEnable() methods to control whether the consult call will be initiated via the conference or the transfer feature. If none of the features is enabled explicitly, transfer gets used by default.

Conference Scenarios

The following scenarios describe the two typical types of conference that can be invoked.

Consult Conference; B as the Conference Controller

The following sequence of steps typically describes this scenario:

  • A calls B (Call 1).

  • B answers.

  • B Consults C (Call 2).

    setConferenceEnable()

    call2.consult(tc, C)

  • C answers.

  • B Completes Conference.

    Call1.conference(Call2)


Note


You must invoke the conference() method on the original call to complete a conference after a consultation. Invoking conference in the consult call object throws an exception.


Arbitrary Conference; B as the Conference Controller

The following sequence of steps typically describe this scenario:

  • A calls B (Call 1).

  • B answers.

  • B places the call on hold.

  • B calls C (Call 2).

  • C answers.

  • B Completes Conference.

    Call1.conference(Call2) or

    Call2.conference(Call1)

Transfer and Conference Enhancement

All parties who are involved in the call transfer get sent CiscoTransferStartEv and CiscoTransferEndEv. All parties who are involved in the call conference get sent CiscoConferenceStartEv and CiscoConferenceEndEv. A call transfer still generates two events—the dropping of a connection to the first call and the creation of a connection to the second call. Cisco Unified Communications ManagerRelease3.1 changed this order of events. Connections first get created in the final call and then get dropped in the consult call.


Note


In Cisco Unified Communications ManagerRelease3.0, not all parties who are involved in the transfer of calls received these events



Note


Applications should not rely on the order of events between CiscoTransferStartEv and CiscoTransferEndEv or between CiscoConferenceStartEv and CiscoConferenceEndEv for transferring and conferencing when porting applications from Cisco Unified Communications ManagerRelease3.0 to 3.1.


Conference and Join

The Conference Feature provides the ability to conference more than two people into a single call. Events at CTI layer change, and Cisco Unified JTAPI gets enhanced to support the new CTI events.

Join Feature provides the ability to join multiple calls into one single conference call. This functionality now supports multiple calls. Applications need to pass an array of calls to be conferenced together.

The following new or changed interfaces exist for conference and joining of multiple calls into one conference call:

  • The following interface allows Join to conference multiple calls into one conference call: Call.Conference(Call[] otherCalls)


    Note


    A precondition requires that all the otherCalls must have controller as one leg of the call.


  • The following new or modified interfaces exist in CiscoConferenceStartEv:

    • TerminalConnection getHeldConferenceController()—This interface proves useful only for the arbitrary conferencing of two calls and returns only one of the held calls.

    • TerminalConnection[] getHeldConferenceControllers()—This interface gets all of the held calls when multiple calls are joined.

    • TerminalConnection getTalkingConferenceController()—This interface returns the talking conference controller; however, if no talking conference controller exists when all the calls that are being joined into conference are held, this interface returns null.

    • Call getConferencedCall()—This interface returns only one of the many calls that are going to join into a conference and may not have any meaning for a join conference when more than two calls exist.

  • New interface in CiscoConferenceEnded event Boolean isSuccess():

    This interface returns true or false depending on whether conference is successful or failed. Application can use interface to find whether conference is successful. The following events get defined as conference failure:

    • If the application issues the request Call.conference(otherCalls[]), this conference would be considered failed if one or more than one calls could join into conference. Applications can use the interface getFailedCalls() to find the failed call.

    • If no conference bridge is available and the conference could not complete at all, the application can use getFailedCalls() to get a list of calls that could not join the conference.

    • A party that was being conferenced dropped out before conference could complete.

  • An interface on the CiscoConferenceEnded event (Call[] getFailedCalls()) gets all the calls that failed to join the conference when the conference fails.

The following new or changed behaviors exist for Conference:

  • No hold or unHold message such as applications see when an arbitrary conference occurs.

  • An arbitrary conference does not require, as a precondition, that any calls be in a talking state; however, all the otherCalls must have a controller as one leg of the call.

  • Applications can conference two or more held calls into a conference call. In finalCall, the controller automatically gets retrieved to a talking state.

  • Always include an active call in the request Call.Conference(otherCalls). If an active call is not included in the conference request, the request fails.

  • If no active call exists at the controller, the Call.Conference(otherCalls) request remains successful; however, if one active call exists, it the request must include it.

  • If the application does not have an active TerminalConnection that is passed as an argument, Call.consult() throws a PreConditionException/InvalidArgumentException.

  • If the controller does not have an active TerminalConnection, Call.Conference()/Call.Conference(Call[]) throws a PreconditionException/InvalidArgumentException.

For details on the interface changes, see Cisco Unified JTAPI Extensions To view the message flow for conference and join, see Message Sequence Charts

Conference Chaining

The conference chaining feature lets applications join two separate conference calls together. JTAPI applications see chained conference calls that are represented as two separate calls. When conference calls are chained, JTAPI creates a new connection for the conference chain and provides the CiscoConferenceChainAddedEv event on CallCtlCallObserver. When the conference chain is removed from the call, JTAPI disconnects the conference chain connection and provides the CiscoConferenceChainRemovedEv event on CallCtlCallObserver. From CiscoConferenceChainAdded/RemovedEv, applications can obtain CiscoConferenceChain, which provides a link for all the conference chain connections.

The following figure shows parties A, B, and C in conference call GC1 and parties C, D, and E in conference call GC2.

Figure 3. Calls Prior to Chaining


After the conference chain is created, the calls will look like the following figure.

Figure 4. Calls After Chaining


Applications may get all the participants of a chained conference from the CiscoChainedConference object, which provides conference chain connections from all the conference calls that are chained together. By browsing through the connections list, applications can get a list of all the chained conference calls; however, applications must have at least one participant of each conference that is observed.


Note


For any conference scenario that involves chaining conferences or adding parties to a chained conference call, JTAPI will not provide ConferenceStarted/Ended event.


For more information, see the following topics:

Consult Without Media

Applications can inform Cisco Unified Communications Manager that a consultation call for a transfer is being placed without establishing the media path. The system does not require establishing the media path for the intermediate call, if the consultation call is being placed to determine whether an agent is available before the actual transfer. The consultWithoutMedia method as defined in the CiscoConsultCall interface creates a consultation call without establishing the media path.


Note


The system allows only transferring of the consultation call; it does not allow the call to be in conference.


CTI Ports

CTI Ports that are registered by an application include a mechanism similar to phone devices. When the Cisco Unified Communications Manager that is handling signaling for a CTIPort fails, the CTIManager recovers its services according to the device pool administration for this device. On a CTIManager failure, Cisco Unified JTAPI reregisters the CTI Port after it connects to the backup CTIManager. The CiscoAddrOutOfServiceEv and CiscoTermOutOfServiceEv events and the corresponding in-service events get sent after recovery of the CTI Port.

The application controls media streaming for these devices, and streaming continues even when the port is out of service. The application has responsibility to ensure that new calls do not get presented to the device until it is ready to accept them.

CTI RoutePoints

On a Cisco Unified Communications Manager server failure, the CTIManager recovers the device from the Cisco Unified Communications Manager server group as defined in the device pool administration for the CTI RoutePoint. When the primary Cisco Unified Communications Manager server recovers, the CTIManager attempts to recover the device on its primary Cisco Unified Communications Manager. This re-homing happens when no more calls exist on the device (similar to physical devices).

On a CTIManager failure, Cisco Unified JTAPI recovers the device on the backup CTIManager. The application receives notification of the availability of a device with the CiscoAddrOutOfServiceEv and CiscoAddrInServiceEv events.

CTI Remote Device for JTAPI

Changes in personal device preferences and an increasing number of mobile and remote workers necessitates a more flexible Unified Communications solution that extends UC features with a Bring Your Own Device philosophy. Extend and Connect addresses this change.

Extend and Connect is a feature that allows administrators to rapidly deploy Unified Communications (UC) Computer Telephony Integration (CTI) applications which interoperate with any endpoint. Extend and Connect lets users leverage the benefits of UC applications from any location using any device. This feature allows interoperability between newer UC solutions and legacy systems, so customers can migrate over time as existing hardware is deprecated.

For more information, please refer to the Cisco Unified Communications Manager Features & Services guide.

Backward Compatibility

Play Announcement

Play Announcement allows a specified preconfigured announcement to be played or streamed to a remote destination. Only announcements that are uploaded to the Cisco Unified Communications Manager can be played. All announcement requirements and limitations are applicable to Play Announcement. As part of this feature, new JTAPI APIs, events, and error codes are added.

Only CTI Remote Devices with a persistent call support play announcement. Play announcement is not supported on IP phones or CTI ports. Cisco recommends that the persistent call plays an announcement when answered. Announcements can be played on persistent calls even without customer calls. However, if there are customer calls incoming to the remote device, announcements are played only when that call is not in a connected state. Multiple announcements cannot be played at the same time. No features (transfer, conference, hold) can be performed on the announcement call.

The following are required for the application to play the announcement: at least one remote destination must be configured, the active remote destination must be set, and a persistent call must be created.

JTAPI supports a new API, CiscoCall.startAnnouncement(), which allows applications to start to play an announcement. This API creates an announcement call. This newly created announcement call counts toward both the busy trigger and maximum calls limit. JTAPI APIs such as Provider.getCalls(), Address.getConnections(), and Terminal.getTerminalConnections() return information for the announcement call.

No new APIs are added to disconnect/drop the announcement calls. Use Existing Call.drop() and Connection.disconnect() JTAPI APIs to disconnect the announcement calls. In addition to the APIs that explicitly end the announcement call, the announcement call is also automatically disconnected after the announcement is complete. Any state change in the announcement call stops the announcement, and also disconnect the announcement call. For example, if there is an incoming customer call in ringing state and the announcement is still being played, after the customer call is answered, the announcement call is disconnected.

As a part of this feature, new JTAPI events are introduced. The CiscoAnnouncementStartedEv is a new JTAPI event that is delivered to applications, notifying applications when the play announcement starts. To notify applications when the play announcement has ended, another new JTAPI event, the CiscoAnnouncementEndedEv, is delivered to apps. If during any time, an error occurs during play announcement, a new JTAPI event delivers that information to apps as well: CiscoAnnouncementErrorEv.

Some of the new JTAPI error codes that are introduced as part of this feature include:

  • CiscoJtapiException.CTIERR_NO_PERSISTENT_CALL_EXISTS: This error codes indicates that no persistent call exists.
  • iscoJtapiException.CTIERR_ANNOUNCEMENT_ALREADY_IN_PROGRESS: This error code indicates that there is already an announcement in progress.
  • CiscoJtapiException.CTIERR_ERROR_PLAYING_ANNOUNCEMENT: This error code indicates that there is an error in playing the announcement.
  • CiscoJtapiException.CTIERR_PLAY_ANNOUNCEMENT_FAILED: This error code indicates that play announcement failed.

Verify Remote Destination Support

In Cisco Unified Communications Manager 10.0(1), the existing CiscoRemoteTerminal.addRemoteDestionation(), CiscoRemoteTerminal.updateRemoteDestination(), and CiscoRemoteTerminal.updateRemoteDestinationNumber() APIs are enhanced to allow validation of the remote destination. As part of this feature, when an application attempts to add or update a remote destination using JTAPI API, Cisco JTAPI validates the remote destination to determine whether the destination is reachable. If the destination is not reachable, the add or update remote destination request returns an error of CiscoJtapiException.CTIERR_EXTEND_AND_CONNECT_DESTINATION_NOT_REACHABLE. The remote destination is then not updated in the database. A sucessful update is possible only if the remote destination is reachable, and the database is then updated with the remote destination number. The verification of the remote destination in the update applies only when the JTAPI API is invoked. Adding or updating the remote destination information through the ccmadmin page does not result in the verification of the remote destination. No new APIs are added as part of this feature. A new error is introduced.

NuRD (Number Matching for Remote Destination) Support

Starting in Cisco Unified Communications Manager 10.0(1), the existing "Cisco Extend and Connect" feature is enhanced to include number matching for remote destination support. When users make a direct call to a number that is configured as a remote destination for CTI Remote Device (CTI RD), and if that remote destination is active, the call is offered on the CTI Remote Device and extended to the remote destination. From the application, the current called party is the CTI RD. If the active remote destination is not set, when users call a remote destination number, the call will be a direct call between the caller and the remote destination. The same situation applies to a call from a remote destination to an enterprise dial number. If the remote destination is active, the CTI RD is initiating the call to the enterprise dial number. If the active remote destination is not set, calls from a remote destination to an enterprise dial number are direct calls between the remote destination and the enterprise dial number.

For those calls from and to a remote destination number, all existing features that are allowed on CTI RD are available.

Interface Changes

There are no interface changes for this feature.

Usage Cases

Use Cases for NuRD (Number Matching for Remote Destination)

Backward Compatibility

This feature may change existing expected behavior in direct calls to and from remote destination numbers. Applications that do not leverage this NuRD feature keep the clusterwide service parameter "Reroute Remote Destination Calls to Enterprise Number" set to False. Enabling the parameter enables the NuRD features. This parameter is set to False by default.

Mobility Interaction Support

Starting in Cisco Unified Communications Manager 10.0(1), the existing "Cisco Extend and Connect" feature is extended to include mobility interaction. Users can now specify remote destinations that are shared between the CTI Remote Device (CTI RD) and the Remote Destination Profile (RDP). When both the CTI RD and the RDP are configured for the same user, and if the application is active (active rd is set), CTI RD will process the call first and then offer the call to the RDP. If the application is not active, the RDP processes the call first and does not offer the call to the CTI RD. When only CTI RD is configured for a user, the existing "Cisco Extend and Connect" feature behavior with remote destinations remains unchanged. When only RDP is configured for a user, there is no application support because the devices are not CTI controllable.

Interface Changes

There are no interface changes for this feature.

Usage Cases

Mobility Interaction Support

Backward Compatibility

This feature is backward compatible and existing applications are not affected by the enhancement.

CTI RD Call Forward

Beginning in Release 10.0(1), CTI RD Call Forward provides applications with the ability to control when incoming calls are forwarded to all configured Remote Destinations on the CTI Remote Device, when no active remote destination is set.

A new check box Route calls to all remote destinations when client is not connected, is added to the Cisco Unified Communications Manager device page. The check box determines whether calls are routed to all remote destinations when active remote destination is not set.

When the check box, Route calls to all remote destinations when client is not connected is enabled, and Active Remote Destination is not set, the call is routed to all remote destinations. If this check box is disabled, and Active Remote Destination is not set, the call will be disconnected with User_Busy error.

In scenarios where Active Remote Destination is set, the call will be always routed to the Active Remote Destination even if the check box Route calls to all remote destinations when client is not connected is selected.

Interface Changes

There are no interface changes for this feature.

Use Cases

CTI RD Call Forward

Backward Compatibility

Applications should enable the check box Route calls to all remote destinations when client is not connected to maintain the old behavior.

CTI Video Support

The CTI Video Support feature allows the JTAPI Application to detect the multimedia capabilities of Line Devices; such as receiving video, sending video and both receiving and sending video. Cisco JTAPI provides the applications with the ability to expose the video capabilities of a terminal through the enhancement CTI Video Support. CTI applications can differentiate a video-enabled device from a non video-enabled device, and, a video call from an audio only call.

Cisco JTAPI provides a new API, getCiscoMultiMediaCapabilityInfo() on the CiscoTerminal to expose the multimedia capabilities of the device. Cisco JTAPI exposes the multimedia capabilities of the terminal after the device is in registered state. The multimedia capabilities of the terminal include:

  • video capability (either none or video enabled),

  • telepresence interoperability (either none or telepresence interoperability enabled on the device), and,

  • screen count (to know the number of screens available on device).

The multimedia capabilities are exposed on a new interface CiscoMultiMediaCapabilityInfo, which has the following APIs to expose these capabilities.

  • getVideoCapability(),

  • getTelepresenceInfo(), and,

  • getScreenCount().

The following APIs on the CiscoCall are used by the application to determine the calling party or called party multimedia capability prior to media setup.

  • getCallingTerminalMultiMediaCapabilityInfo()—of the calling party in a call

  • getCalledTerminalMultiMediaCapabilityInfo()—of the called party in a call

When the video capability of the terminal changes, a new Cisco JTAPI event, CiscoProvTerminalMultiMediaCapabilityChangedEv, notifies the application. This event is a JTAPI provider event, and is delivered when the application adds a Provider Observer. The terminal must be in registered state, to receive this event. Plugging in or plugging out the Cisco camera will not affect the video capability status, therefore, the event will not be triggered. However, you can modify the video capability using the Cisco UCM Administration Interface > Device Configuration page.


Note


The initial video capability API on CiscoTerminal is not supported for CTI Route Points and CTI Ports; however, they can receive the video information of the calling party.


The following devices supports the CTI Video feature:

  • 89xx (SIP only)

  • 99xx

  • E20

  • EX60/90

  • CTS 500

  • CTS 500-32

  • Jabber(CSF)

  • CTI RoutePoint

  • CTI Port

Interface Changes

Message Sequences

Backward Compatibility

This feature is backward compatible.

Default CTI IP Addressing for Devices

A new CTIManager service parameter, IP Addressing Mode for Devices, has been added that allows you to configure the default CTI IP addressing mode for a device that does not have an associated Common Device Configuration.

When an application invokes the CiscoTerminal.getIPAddressingMode() method for a device that does not have a Common Device Configuration, JTAPI returns the value of the service parameter. The default setting for the new service parameter is IPv4 and IPv6. JTAPI communicates the value via CiscoTerminal.IP_ADDRESSING_MODE_IPV4_V6.


Note


For an individual CTI device, if that device has an associated Common Device Configuration, the IP Addressing Mode setting in the Common Device Configuration overrides the value of the IP Addressing Mode for Devices service parameter.

DeleteCall

DeleteCall interface provides applications with the ability to delete a call that was created by using the createCall interface. This method accepts a call and throws an InvalidStateException if a provider is not in service or if the call is not in the IDLE state. DeleteCall moves the call to the INVALID state.

The following interface gets added to CiscoProvider:

{ public void deleteCall( Call call ) throws InvalidStateException;
}

Applications can use this interface to delete the call that was created by using createCall interface. This method accepts a call and throws an InvalidStateException if the provider is not in service or if the call is not in the IDLE state. DeleteCall moves the call to the INVALID state.

To successfully delete a call, the application creates the call by using createCall, and the call should be in the IDLE state.

Device Recovery

Cisco Unified JTAPI supports automatic device recovery.

Device Recovery for Phones

For devices such as the Cisco Unified IPPhone 7960, the re-homing feature represents part of the device firmware. On a primary Cisco Unified Communications Manager failure, the phone attempts to connect to the backup Cisco Unified Communications Manager when it is no longer on a call. This transition gets communicated to applications in the form of out-of-service and in-service events described in CTIManager Failure.

For virtual devices with no firmware such as CTI Ports and CTI RoutePoints, the CTIManager or Cisco Unified JTAPI performs the failover.

Device State Server

The Device State server provides the cumulative state of all the addresses on a terminal. These events are delivered as TerminalEvent. Applications need to add TerminalObserver to get these events.

The states follow:

  • IDLE—If no calls exist on any of the addresses on the terminal, consider the DeviceState as IDLE, and Cisco Unified JTAPI sends CiscoTermDeviceStateIdleEv to applications.

  • ACTIVE—If any addresses on the terminal have an outgoing call (in CTI State Dialtone, Dialing, Proceeding, Ringback, or Connected) or an incoming call (in CTI State Connected), the consider DeviceState as ACTIVE, and Cisco Unified JTAPI sends CiscoTermDeviceStateActiveEv to the application.

  • ALERTING—If address on the terminal has an outgoing call (in CTI State Dialtone, Dialing, Proceeding, Ringback, or Connected) or an incoming call (in CTI State Connected) and at least one of the addresses on the terminal has an unanswered incoming call (in CTI State Offering, Accepted, or Tinging), the DeviceState is ALERTING, and Cisco Unified JTAPI sends CiscoTermDeviceStateAlertingEv to the application.

  • HELD—If all the calls on any of the address on the terminal are held (in CTI State OnHold), the DeviceState is HELD and Cisco Unified JTAPI sends CiscoTermDeviceStateHeldEv to the application.

New Events

  • CiscoTermDeviceDeviceStateIdleEv

  • CiscoTermDeviceStateActiveEv

  • CiscoTermDeviceStateAlertingEv

  • CiscoTermDeviceStateHeldEv

New and Changed Interfaces

public int getDeviceState() returns the device state of the terminal.

Direct Transfer Across Lines

The Direct Transfer Across Lines feature allows support for connected transfer across lines. It allows two calls on different addresses of the same terminal to be transferred though the Transfer softkey on the phone or by using the transfer() API that is provided by Cisco Unified JTAPI. When a transfer is performed across lines, the JTAPI application behavior changes, as applications do not see a common controller address in final and consult calls. There is no change in the API and the same events are delivered whether calls are transferred on the same address (regular transfer) or across addresses (direct transfer across lines). This feature is supported on all supported phones, including CTI port, SCCP devices and SIP devices.

If an observer is not added to either of the two addresses from which the direct transfer is being attempted from the JTAPI API, then Cisco Unified JTAPI throws PlatformException with this error: Transfer controller is not set and could not find a suitable TerminalConnection.

Usage Guidelines

The points below indicate how applications must use the Direct Transfer Across Lines feature:

  • Applications must add Call Observer on the both the lines across which they try a direct transfer.

  • Earlier, applications were recommended to check if both the calls have a common address and if that address is on the same Terminal. For Direct Transaction Across Lines, it is not required to check this, if the address is common between two calls across which direct transaction is invoked. It must be ensured that both the calls should each have an address which exists in a common terminal.

  • Cisco Unified JTAPI reports the same set of events, as it does currently, for transferring of a call on same address. Applications are not required do anything with these calls after invoking Transfer() until receiving CiscoTransferEndEv.

  • As transfer is done across addresses, applications do not get a common controller in CiscoTransferStartEv and should upgrade the application logic.

Note


There is no common address for controllers in final and consult call, but the controller TerminalName is same for both the controller Addreses. So, application should rely on CommonTerminalName to find out the connections, terminal connections and controllers.

Backward Compatibility

This feature is backward compatible. To provide backward compatibility for applications, a new permission to devices that allow connected transfer across lines has been added, along with a new standard role and a standard user group for this permission. Applications can control these devices only if this new role Standard Supports Connected Xfer/Conf is associated to the application user. Applications will be able to control these devices only if this new role "Standard CTI Allow Control of Phones supporting Connected Xfer/Conf" is associated to the application user. So, by default these devices are listed as restricted, assuming that the application uses JTAPI 7.1.2 or higher and only if application upgrades to handle this feature and associates the new permission can it control these devices. If the application uses an older JTAPI client the devices are not restricted but if the application tries to observe these devices (which supports this feature to be invoked manually), JTAPI throws an exception and marks these devices as restricted from there on.

However, the application can invoke DirectTransfer Across Lines from existing JTAPI transfer() API on any type of phone and there is no restriction on this behavior as applications are expected to issue this request only if they support this feature. Also, a FarEnd point performing a Direct/Connected Transfer Across Lines is uncontrolled and can cause problems to applications. This means that JTAPI always reports events for Direct Transfer Across Lines for all the phones.

Be aware that any old JTAPI application will not have any BWC issues if it is run in an environment where Direct Transfer Across Lines is not invoked (either on phones or through JTAPI API). However, applications changes are required if this this feature is used in such a setup.

Cisco assumes that two or more applications do not control or observe the same terminal or address simultaneously. If they do, all instances of this application make changes to support this feature or coordinate to avoid any problem. Otherwise, application behavior may be unforeseen. For example, if App1 and App2 are two applications controlling or observing the same terminal or address and App1 makes changes to support this feature then App2 is also expected make changes to support the feature. Else, invocation of this feature by App1 on common devices can break App2.

As, the feature is designed to provide an enhanced user experience, Cisco strongly recommends that all Cisco Unified JTAPI applications should evaluate and support this feature and upgrade if necessary with the code logic to handle both the old and new behavior.

Directed Call Park

This feature allows the user to park a call by transferring the call to a user-selected park code.

Examples

A calls B; B transfers the call to a parked DN. On completion of the transfer, the A to B call is parked at the specified parked DN. A will receive MOH (if configured). When C unparks the call (by dialing the prefix code and park code), A and C connect.

If A calls the parked DN directly, A connects to the parked DN, and the system marks this parked DN as busy. A stays connected to this parked DN until park reversion.

If C does not unpark the call at the parked DN, the call park reverses to the DN that parked the call (B), and A and B connect again. B can again try to d-Park to another parked DN. When park reversion occurs, Cisco Unified Communications Manager JTAPI passes a new reason code to the application.

CTI sends the parked number to Cisco Unified Communications Manager JTAPI in the form "Park Number: (<Prefix Code>)<DPark DN>". Cisco Unified Communications Manager JTAPI parses this and exposes both Prefix Code and DPark DN to applications.

When a call is unparked, the parked party and unparking party both receive a CPIC event with the reason given by CTI, and the parked party connects to the unparking party.

When party A calls a dPark DN and party B also calls the same dPark DN, the system can connect either A or B to the dPark DN, and the other party is disconnected.

Cisco Unified Communications Manager JTAPI Support

Cisco Unified Communications Manager JTAPI supports this feature. When the system transfers a call to a directed call park DN (dparked), the application sees a connection created for directed call park DN, and the call control connection state is CallControlConnection.QUEUED. The system delivers CiscoTransferstart and end events. An application can use the new interface on CiscoConnection to get the prefix code needed to unpark the call.

Performance and Scalability

This feature provides the same performance impact as the existing transfer feature.

Directory Change Notification

Applications require notification asynchronously of device additions or deletions from the user control list and device deletions from the Cisco Unified Communications Manager database. Applications also receive notification about line changes to a device. This notification gets sent to Cisco Unified JTAPI and propagates to applications with CiscoAddrCreatedEv, CiscoAddrRemovedEv, CiscoTermCreatedEv, and CiscoTermRemovedEv on the AddressObserver and TerminalObservers, respectively.


Note


Ensure that the device is registered for CTIPorts and CTIRoutePoints to receive the line change notification.


Do Not Disturb

Do-Not-Disturb (DND) gives phone users the ability to go into the DND state on the phone when they are away from their phones or do not want to answer the incoming calls. The DND softkey enables and disables this feature.

From the user windows, users can configure the following settings for DND:

  • DND Option-Ringer off

  • DND Incoming Call Alert-beep only/flash only/disable

  • DND Timer-value between 0-120 minutes. It specifies a "period in minutes to remind the user that DND is active".

  • DND status-on/off


Note


The Application can only enable or disable the DND status.


  • The Application can set the DND status by invoking a new interface on CiscoTerminal.

  • JTAPI will also query the application about any change in the DND status when DND status is set by phone, Cisco Unified Communications Manager Administration, or application.

  • The application must enable the filter in CiscoTermEvFilter to receive the preceding notification.

  • The application can also query for the DND status through a new interface on CiscoTerminal.

  • The application can also query for the DND option through a new interface on CiscoTerminal.


Note


This feature applies to phones and CTI ports. It does not apply to Route points.


In the case of emergency calls (made by a CER application) landing on an application that has DND enabled, the system overrides the DND settings and presents the call to the application. A new parameter, FeaturePriority, in the redirect() and selectRoute() APIs on CiscoCall, CiscoConnection, and CiscoRouteSession, respectively, makes this possible. The CER application that initiates the emergency call sets FeaturePriority as FeaturePriority_Emergency. The application sets the feature priority only for emergency calls. In the case of normal calls, applications either do not set the feature priority at all or set it to FeaturePriority_Normal. Applications do not set FeaturePriority_Emergency in case of normal calls. When initiating feature calls such as intercom, applications must specify FEATUREPRIORITY_URGENT.


Note


The connect() API on CiscoCall does not support the FeaturePriority parameter.


The application receives an exception if it tries to perform a getDNDStatus(), setDNDStatus(), or getDNDOption() before the device is in service.

A Post condition is added to DND to handle a DB update failure or device out-of-service situations if they occur after the setDNDStatus() request is sent. If a DB update failure or device out-of-service condition occurs after the setDNDStatus() request is sent, setDNDStatus() delivers a CiscoTermDNDStatusChangedEv to the application. If this event is not received, a post-condition time-out occurs, and the following exception is thrown: could not meet post conditions of setDNDStatus().

Backward Compatibility

This feature is backward compatible. Applications recognize new events if this feature is configured. You can filter the new events through the TerminalEventFilter interface (CiscoTermEvFilter). By default, this filter is disabled and the system does not deliver the new events.

For additional information, see the following topics:

Do Not Disturb-Reject

Do Not Disturb–Reject (DND–R) is an enhancement to the existing DND feature. Cisco Unified Communications Manager and JTAPI previously supported only the Ringer off DND. The user can reject calls with DND–Reject. You can set DND–R from the phone configuration window or the phone profile configuration window in Cisco Unified Communications Manager Administration.

When DND–R is enabled, the call is not presented to the terminal that has Call Reject enabled. There is no audible or visual indication of incoming calls on that end point. To enable DND–R, set the DND Status as true and the DND option to Call Reject.

FeaturePriority overrides DND. It can have any of the following values:

  • 1: Normal

  • 2: Urgent

  • 3: Emergency

This release introduces FeaturePriority in connect() API on CiscoCall. FeaturePriority in selectRoute() and redirect() API is already supported in prior releases. When feature priority as EMERGENCY is specified in connect() API, and the destination terminal has DND–R enabled, the call still rings at the destination terminal and overrides the DND–R settings.

When a terminal has DND–R enabled and receives an intercom call, DND–R settings are overridden and call presents. This is because feature priority is always 2 (URGENT) for intercom calls.

In non- shared line scenario where A calls B and Terminal B has DND–R enabled, CallCtlConnFailedEv with cause USER_BUSY is delivered on A. Users would see the same behavior if DND–R is enabled on all the terminals that have shared DNs.

In the case of shared lines when at least one of the terminal does not have DND–R enabled and a call is placed to the shared line, Cisco Unified JTAPI delivers TermConnPassiveEv and CallCtlTermConnInUseEv for the terminals that have DND–R enabled (assuming the call was made with NORMAL feature priority). TermConnPassiveEv and CallCtlTermConnBridgedEv is delivered if DND–R is disabled on the terminal during a call.

A new event CiscoTermDNDOptionChangedEv will be sent to the terminal observer whenever the DND option changes on the phone window or Common Phone Profile window in Cisco Unified Communications Manager Administration.

Default DND option is Ringer–off and Route points do not support DND.

Backward Compatibility

Drop Any Party

This feature provides the capability to drop any participants from a conference call. Cisco Unified JTAPI allows applications to drop participants from conference using the existing interface Connection.disconnect() even if the application is not observing the address for the connection. Previously, applications could only disconnect connections for which Address is an observed Address.

Feature behavior varies based on the settings for the Cisco Unified Communications Manager service parameter Advanced Ad Hoc Conference Enabled. If this service parameter is set to False, applications can drop connections for an unobserved address in a conference call only if the application observes the conference controller's address. If this parameter is set to True, applications can drop connections without any restriction.

Cisco Unified JTAPI provides an interface on CiscoConnection to get an array of CiscoPartyInfo objects for the connection. CiscoPartyInfo is used to disconnect participants from a conference using a new interface, disconnect(), provided on CiscoConnection. A normal line has only one CiscoPartyInfo on its connection, but a shared line has one CiscoPartyInfo for each line in the shared line. This enables applications to selectively disconnect a shared line participant if more than one shared line participants are in the conference call. Since shared line participants have only one connection, if the application uses the existing Connection.disconnect() API, it drops all the shared line participants.

Cisco Unified JTAPI provides an interface setDropAnyPartyEnabled() on CiscoJtapiProperties to enable or disable this feature and by default, it is enabled. Alternatively, applications can have the JTAPI ini parameter dropAnyPartyEnabled = 0 in jtapi.ini file to disable Drop Any Party feature and dropAnyPartyEnable = 1 to enable this feature. If dropAnyPartyEnable parameter is not present in jtapi.ini file, the feature is enabled by default.

Cisco Unified JTAPI also provides an interface, isConferenceCall(), on CiscoCall to determine if a call is a conference call. This simple method returns a Boolean.

Backward Compatibility

Dynamic CTI Port Registration

This feature lets applications provide an IP address (ipAddress) and port number (portNumber) for each call or whenever media is established. To use this feature, applications must register the media terminal by supplying media capabilities. When a call is answered at this media terminal, CiscoMediaOpenLogicalChannelEv is sent to applications. This event gets sent whenever media is established. Applications must react to this event and specify the IP address and port number where media gets established.

A CiscoMediaTerminal represents a special kind of CiscoTerminal that allows applications to terminate RTP media streams. Unlike a CiscoTerminal, a CiscoMediaTerminal does not represent a physical telephony endpoint, which is observable and controllable in a third-party manner. Instead, a CiscoMediaTerminal represents a logical telephony endpoint, which may be associated with any application that terminates media. Such applications include voice messaging systems, interactive voice response (IVR), and softphones.


Note


Only CTIPorts appear as CiscoMediaTerminals through Cisco Unified JTAPI.


Terminating media comprises a two-step process. To terminate media for a particular terminal, an application adds an observer that implements the CiscoTerminalObserver interface by using the Terminal.addObserver method. Finally, the application registers its IP address and port number to which the terminal incoming RTP streams get directed by using the CiscoMediaTerminal.register method.

To register the ipAddress and portNumber dynamically on a per-call basis, applications must register by only providing capabilities that they support. Applications must react to CiscoMediaOpenLogicalChannelEv that gets sent whenever media is established. If any features are performed before applications react to CiscoMediaOpenLogicalChannelEv, the features may fail.

If the applications do not respond to this event during the time that is specified in the Media Exchange Timer in the Cisco Unified Communications Manager Administration windows, the call may fail.

The following new or changed interfaces exist for Dynamic CTIPort Registration Per Call:

Interface CiscoMediaOpenLogicalChannelEv Extends CiscoTermEv

int

getpacketSize()

Returns the packet size of the far end in milliseconds.

int

getPayLoadType()

Returns the payload format of the far end, one of the following constants:

CiscoRTPHandle

getCiscoRTPHandle ()

Returns the CiscoTerminalConnection object on which applications must invoke the setRTPParams request.

Interface CiscoRTPHandle

int

getHandle()

Returns an integer representation of this object, currently the Cisco Unified Communications Manager CallLeg ID.

CiscoCall

getCall (CiscoRTPHandle rtpHandle)

Returns the call object with the rtpHandle that is associated with a specific terminal. If no callobserver gets added to the terminal at the time when the applications receive CiscoRTPHandle in CallOpenLogicalChannelEv, CiscoCall may be null.

E911 Teleworker

The main purpose of this feature was intended to provide Location awareness for teleworkers and off premise users so that they can make emergency calls from off premises. The API's can also be used by all applications in a generic way as described below.

Primarily this feature adds two JTAPI API methods (selectRoute & redirect) that are overloaded to add an additional XML parmater to the list of their exisiting parameters. Any application can use these overloaded selectRoute() and redirect() methods to pass XML data to the call receiving side. The format of the XML data that can be passed is seen below:

<data>
     <item>
         <type>contact</type>
         <operation>append</operation>
         <protocol>SIP</protocol>
         <value>;+sip.instance = &quot;&lt;urn:uuid = *guid*&gt;&quot;</value>
     </item>
</data>

When an application sends XML data using one of the above API, CTI parses the data and extracts the text from the 'value' node in the XML and passes it on to CCM. CCM will then append this text to the outgoing SIP Invite message 'contact:' header. Once the end points like the SIP trunk or the SIP phone receives it, they can extract that data from the contact header and process it. Currently only SIP protocol's contact header field data is the only one supported but this can be expanded to include others headers fields and other protocols in future releases.

In the current release of CUCM only the following values for the XML nodes are supported: type: contact, operation: append, protocol: SIP. The value node in the above xml format is the one that carries the required application data to the end point.

The new parameter is a double byte array for overloaded selectRoute () Method to accommodate xml data for each selected routes and single byte array for the redirect () method. The parameter takes either a XML format String or a NULL value.

Enable or Disable Ringer

The CiscoAddress extension allows applications to set the status of the ringer for all lines on a device. No events generate when the ringer setting gets changed from the administration windows or anywhere else.

Encryption Enhancement

Unified Communications Manager Release 10.0(1) adds support for public key encryption which is more secure than the former symmetric key method. All JTAPI clients must be upgraded to the latest version bundled with Unified Communications Manager Release 10.0(1) to leverage this security enhancement. The JTAPI client is available under the “Applications-Plugins” menu from CCMAdministration.

The service parameter “Require Public key encryption” has been added. This parameter determines the encryption method required by Unified Communications Manager when authenticating CTI applications. When set to True, Unified Communications Manager requires CTI applications to authenticate using public key encryption; available in JTAPI client version 10 or later. When set to False (default), Unified Communications Manager allows CTI applications to authenticate by using either symmetric key or public key encryption. CTI applications must upgrade JTAPI/TSP client plugins to version 10.0(1) or later to authenticate when using public key encryption.

Although there are no interface changes for this enhancement, Cisco recommends that applications update CiscoJTAPI libraries to take advantage of this security enhancement.


Note


No changes are required in the application layer. Applications need to update the Cisco JTAPI to the 10.x version to leverage the new security enhancement.

Note


Cisco recommends that applications upgrade their Cisco JTAPI versions and set this service parameter to true. In future releases this service parameter will be deprecated.

Backward Compatibility

To maintain backward compatibility, a new CTI Manager service parameter is introduced:

End to End Call Tracing

This feature enables the application to track any call uniquely. JTAPI associates a uniqueID with every Connection object. The same ID is exposed to the application through a new API getUniqueID(Terminal term) on the interface CiscoConnection. This uniqueID is only available for connection of observed addresses.

When a connection is created, the application can receive the uniqueID and write it in the Call Details Record. For Shared Line scenarios, each shared line has a uniqueID, which can be retrieved by passing the corresponding Terminal to getUniqueID API. UniqueID may or may not be the same for different shared lines depending on the scenario. The application can query the uniqueID corresponding to each shared line on receiving TermConnActiveEv for that shared line Terminal.

Whenever the uniqueID changes, JTAPI delivers CiscoConnectionUniqueIDChangedEv to the call observer of the application.


Note


As of Release 8.0(1), there is no supporting use case where JTAPI delivers CiscoConnectionUniqueIDChangedEv event to the application.

EnergyWise Deep Sleep Mode

This feature allows the phone to participate in an EnergyWise enabled system. The phone reports its power usage to a EnergyWise compliant switch to allow the tracking and control of power within the customer premise. The phone provides alternate reduced power modes including an extremely low, off mode. The Cisco Unified Communications Manager administrator configures and exclusively manages the phones power state through vendor specific configuration on the Cisco Unified CM Admin pages.

When the phone turns off power after negotiation with an EnergyWise switch, it unregisters from Cisco Unified CM and enters Deep Sleep/PowerSavePlus mode. Phones automatically re-register back with the Cisco Unified CM once the Deep Sleep mode configured PowerON time is reached.

However, you can press the ‘select’ key on the Cisco Unified IP Phones Series 9900 and 6900 while in Deep Sleep/PowerSavePlus mode to wake up the phone, these phones automatically power on and re-register back with the Cisco Unified CM. However, for Cisco Unified IP Phones 7900 Series phones, you can neither power on nor re-register back with the Cisco Unified CM during Deep Sleep/PowerSavePlus mode unless the ‘PowerON’ time is reached. You can configure Deep Sleep mode on the Device page of the Cisco Unified CM. Configure Deep Sleep mode for the phones at least 10 minutes before the actual power off time to allow the information to synchronize between the switch and the phone.

The Power off idle timer enables only in the case when there is physical interaction on the phone. For example if there is a call on the EnergyWise configured phone during the deep sleep time and the user tries to disconnect the call from the application, then the power off idle timer defaults to 10 minutes but if the user disconnects the call manually from the phone, then the power off idle timer takes the value configured on the Cisco Unified CM device page.

When a terminal unregisters from Cisco Unified CM, JTAPI exposes CiscoProvTerminalUnRegisteredEV event to application with a new reason "CiscoProvterminal UnRegisteredEV.ENERGYWISE_POWER_SAVE_PLUS".

JTAPI sends CiscoTermOutOfServiceEv event to the application with the cause "CiscoOutOfServiceEv.CAUSE_ENERGYWISE_POWER_SAVE_PLUS" when a terminal goes out of service due to Deep Sleep mode configured.

JTAPI sends CiscoAddrOutOfServiceEv event to application with a new cause "CiscoOutOfServiceEv.CAUSE_ENERGYWISE_POWER_SAVE_PLUS" when an address goes out of service due to Deep Sleep mode configured.

Extension Mobility Cross Cluster

This feature allows users to log in to an IP phone registered to a cluster with user profiles configured with another cluster. The Extension Mobility feature allows a user to log in to an IP phone to appear as user's desk phone temporarily, subject to the administrative policy. After logging on to an IP phone, the user can receive incoming calls normally routed to the user's desk phone and retain the personalized configuration, such as speed dials, services links and other user-specific properties.

Currently, Extension Mobility service is limited to a single Cisco Unified Communications Manager (Cisco Unified Communications Manager) cluster. A user provisioned in one cluster today cannot log in to an IP phone of another cluster with the Extension Mobility feature, even though both clusters may belong to the same enterprise. This limitation is overcome with the introduction of this new feature, which allows the user provisioned in one cluster to log in to an IP phone of another cluster.

With the existing behavior, when a user logs in to a terminal with a user ID that matches the user ID used by Cisco Unified Communications Manager JTAPI application, the terminal is treated as part of the control list and application is able to add call observer on the terminal and/or address.

As part this feature support, Extension Mobility profiles can be added to the user's control list via the Cisco Unified Communications Manager Admin pages. When a user uses Extension Mobily to log into a device using a profile in the control list, JTAPI delivers CiscoAddrCreatedEv and CiscoTermCreatedEv, and application can add call observer to control the terminal or address.

JTAPI exposes getCiscoCause () API on all provider events. For provider events associated with non-Extension Mobility login or logout scenarios, the cause delivered will be CiscoProvEv.NORMAL. For provider events associated with Extension Mobility login or logout scenario, the cause may be any of the below depending on the type of Extension Mobility login or logout:

CiscoProvEv.CAUSE_EM_LOGIN                    CiscoProvEv.CAUSE_EM_LOGOUT        CiscoProvEv.CAUSE_EM_LOGIN_PROFILE_ADD CiscoProvEv.CAUSE_EM_LOGOUT_PROFILE_REMOVE 

Interface changes explain more about each of these causes.

The following is a complete set of provider events that have API getCiscoCause():

CiscoAddrActivatedEvCiscoAddrActivatedOnTerminalEv
CiscoProvFeatureEv
CiscoProvTerminalCapabilityChangedEv
CiscoAddrRestrictedEv
CiscoTermActivatedEv
CiscoTermRestrictedEv
CiscoAddrCreatedEv
CiscoTermCreatedEv
CiscoAddrRemovedEv
CiscoTermRemovedEv
CiscoAddrAddedToTerminalEv
CiscoAddrRemovedFromTerminalEv.

JTAPI exposes getLoginType () on CiscoTerminal to indicate if the terminal is part of the Home or Visiting cluster when a user does an Extension Mobility login or logout. Accordingly, return value will be CiscoTerminal.NO_LOGIN, CiscoTerminal.NATIVE_LOGIN or CiscoTerminal.VISITOR_LOGIN.

Home Cluster is the Cisco Unified Communications Manager cluster from which the traveling EMCC user starts. This is the user's home cluster where the user profile resides.

Visiting Cluster is the Cisco Unified Communications Manager cluster which the traveling EMCC user visits. This is also the cluster that owns the phone at which the user does Extension Mobility login.

External Call Control

External Call Control enables Cisco Unified Call Manager (Cisco Unified Communications Manager) to route calls based on enterprise policies and presence-based routing rules of individual users. When call intercept is enabled, Cisco Unified Communications Manager queries the designated web services hosting the enterprise policies or user rules and routes the calls following the routing decisions returned.

External Call Control

Backward Compatibility

This feature is backward compatable. Existing applications will not be impacted by the changes for this feature. There are, however, implications and limitations to applications regarding Wildcard Routepoints as they exist today, which are being addressed by adding a service parameter, described below. Applications that do not use Wildcard Route Points will be completely unaffected by this development.

The first is that an application controlling wildcard routepoints used to get three JTAPI connections on a call. One with the caller, the second with the dialed Directory Number and the third with the wildcard routepoint that JTAPI is observing. The third connection has been removed with this feature.

The second backward compatability issue is with the various called party fields during a Wildcard Routepoint scenario. Before implementation of this feature, CiscoCall.getCalledAddress() and CiscoCall.getCurrentCalledAddress() both returned the actual dialed Directory Number, and it was not possibl eto retrieve the Wildcard Directory Number. After this fix, both CiscoCall.getCalledAddress() and CiscoCall.getCurrentCalledAddress() return the Wildcard Directory Number, while CiscoCall.getModifiedCalledAddress() returns the actual dialed Directory Number. This is a fix for an issue that built an errorenous call model in JTAPI, but it may cause applications using this feature in this way to break.

Both these issues have been addressed by adding a new service parameter at the CTI layer, known as Use WildCard pattern in CTI Call Info. This service parameter is set to OFF by default and continues the existing behavior. If an application wants to take advantage of the new information provided to it regarding Wildcard Routepoints, the service parameter must be changed to ON. This service parameter applies only when wild card Route Point is the called party. You must note that there are use cases for this feature that provide details of the Wildcard Routepoint scenario with the service parameter set to both ON and OFF, but the use case where it is set to OFF is currently not supported, shows the call flow as it exists today.

End to End Session ID for Calls

Cisco Unified Communications Manager generates a unique session identifier for each leg in a call. This feature enables the application to track a call end to end uniquely with a Session ID.

Cisco JTAPI exposes the following new methods for applications to get unique session identifiers for each connection in a call:
  • CiscoConnection.getLocalUUID(TerminalConnection)
  • CiscoConnection.getPeerUUID(TerminalConnection)

The methods accept a TerminalConnection object associated to that connection as a parameter, and return a String representing the UUIDs of the local and peer participant in a given CiscoConnection respectively. If a null object is passed as a parameter, the methods will return the UUID of the active TerminalConnection in the CiscoConnection.

The SessionID is acquired by merging the localUUID and the peerUUID in the following format:
device=<localUUID>;remote=<peerUUID>;

The Session ID is generated within Cisco Unified Communication Manager for non-SIP devices. SIP devices generate their own Session IDs and publish them in the SIP INVITE message to Cisco Unified Communication Manager. This information is visible to the application through the respective interface.

The Local Universal Unique Identifer (localUUID) for a CiscoConnection in a CiscoCall is generated in the peerUUID on the other side in the CiscoCall and vice versa.

This relation is assured for a basic two party call and is retained through the following features:
  • Redirect

  • Call Forward

  • Transfer

  • Hold/Resume

If the Cisco call is shared between multiple devices, the CiscoConnection.getPeerUUID(null) on the calling side will return the UUID of any of the available terminals while the CiscoConnection on the called side is in CiscoConnection.ALERTING state. Once the call is answered CiscoConnection.getPeerUUID(null) on the calling side will return the uuid of the active TerminalConnection.

FIPS Compliance

This feature allows Unified Communications Manager to operate in Federal Information Processing Standard (FIPS) mode. FIPS specifies a minimum security level for cryptographic functions, limitations on how data is stored, and which algorithms are allowed to be used to encrypt sensitive information. These strictly defined requirements are important to government agencies, hospitals, and other customers who're interested in a higher level of security.

To enable FIPS Compliance, Unified Communications Manager applications must request this mode when they download certificates with JTAPI and open a provider. When operating in FIPS, Unified Communications Manager experiences minimal performance loss. You can only witness this loss during the certificate downloads and opening of a Cisco Unified Communications Manager JTAPI provider. FIPS does not affect anything when the application is running.

Starting from Release 8.6(1), JTAPI can be configured as FIPS-compliant.

Important Notes

In FIPS, there are two distinct "cryptographic entities": The JTAPI application and the Unified CM server (or cluster). The FIPS compliance of one does not, in any way, affect the other. Setting JTAPI to run in FIPS compliance encrypts the client-side certificates with a FIPS-compliant algorithm, and connect using only approved SSL/TLS algorithms. It will not make the Unified CM server or cluster secure or FIPS-compliant.

Likewise, having the Unified CM operate in FIPS mode will not make JTAPI store certificates with FIPS-compliant algorithms. They are distinct items, separated by a”cryptographic boundary.”

Also, even if JTAPI operates in FIPS-compliant mode, your application may not. Your applications must handle cryptographic information and other sensitive data with special attention to be FIPS-compliant.

As mentioned earlier, applications that need to use FIPS compliance must not only explicitly request it, but also download cryptographic libraries and modify their classpath variables to include them.

Until Unified Communications Manager Release 12.5(1), JTAPI used RSA libraries for FIPS-compliant operations. With Release 12.5(1) and later, JTAPI on Windows uses RSA libraries, while on Linux it uses CiscoJ libraries.

As of Unified Communications Manager Release 14SU2, JTAPI uses BCFIPS libraries for all security-related operations. If configured to operate in FIPs mode, JTAPI moves BCFIPS libraries to approved only mode to enforce FIPS compliance.

The libraries are detailed below:

The RSA libraries are:

"jcmFIPS.jar" "cryptojcommon.jar", " cryptojce.jar" and "sslj.jar", are FIPS-compliant libraries from RSA, Inc.

The CiscoJ libraries are:

The CiscoJ libraries are "CiscoJCEProvider.jar", "log4j-1.2.17.jar", "slf4j-api-1.7.24.jar", "slf4j-log4j12-1.7.24.jar", "slf4j-simple-1.7.24.jar", "bcpkix-jdk15on-154.jar", and "bcprov-jdk15on-154.jar".


Note


From Release 12.5(1)SU5 on this train and up to 14SU1, "bcpkix-jdk15on.jar" and "bcprov-jdk15on.jar" are used instead of "bcpkix-jdk15on-154.jar" and "bcprov-jdk15on-154.jar" respectively.



Note


From Release 14SU2 to 15SU1, the BCFIPS libraries are:

  • bc-fips.jar (version 1.0.2.3)

  • bctls-fips.jar (version 1.0.12.3)

  • bcpkix-fips.jar (version 1.0.5)



Note


From Release 15SU2 onwards, the BCFIPS libraries are:

  • bc-fips.jar (version 2.0.0)

  • bctls-fips.jar (version 2.0.19)

  • bcpkix-fips.jar (version 2.0.6)

  • bcutil-fips.jar (version 2.0.1)

If you're upgrading the BCFIPS jars in your runtime environment to the latest supported (2.x as aforementioned) and an application is using an older jtapi.jar (earlier than 15SU2), while setting up the application environment, you must explicitly set "org.bouncycastle.jsse.fips.allowRSAKeyExchange" to True as a runtime system property to ensure that CAPF operation succeeds.


These libraries contain special implementations of several key cryptographic functions that replace the older implementation in jtapi.jar.

If your application contains a lib folder where third-party libraries are stored, the classpath looks as follows:

  • For the JTAPI plugin using RSA libraries (refer above for library usage information as per the Unified Communications Manager release):

    ./libs/jcmFIPS.jar;./libs/cryptojcommon.jar;./libs/cryptojce.jar;./libs/sslj.jar;./libs/jtapi.jar

  • For the JTAPI plugin using CiscoJ libraries (refer above for library usage information as per the Unified Communications Manager release):

    ./libs/CiscoJCEProvider.jar;./libs/CiscoJUtils.jar;./libs/CiscoJCEJNI.so;./libs/libssl.so;

    ./libs/libssl.so.1.0.1;./libs/log4j-1.2.17.jar;./libs/libciscosafec.so;./libs/libciscosafec.so.4;

    ./libs/libciscosafec.so.4.0.1;./libs/libcrypto.so;./libs/libcrypto.so.1.0.1;

    ./libs/slf4j-api-1.7.24.jar;./libs/slf4j-log4j12-1.7.24.jar;./libs/slf4j-simple-1.7.24.jar;

    ./libs/bcpkix-jdk15on.jar;./libs/bcprov-jdk15on.jar;./libs/jtapi.jar

  • For the JTAPI plugin using BCFIPS libraries (refer above for library usage information as per the Unified Communications Manager release):

    ./libs/bc-fips.jar;./libs/bcpkix-fips.jar;./libs/bctls-fips.jar;./libs/jtapi.jar

Even with the classpath set this way, the JTAPI security code works the same way it does now unless the application specifically requests to run in FIPS mode.

To request that JTAPI run in a FIPS-compliant mode, applications must use some of the new methods that are introduced as part of this feature development and specify the new "fipsCompliant" parameter as True. For more information, see the following "Interface Changes" section.

Interface Changes

CiscoJtapiPeerImpl, CiscoProvider, and CiscoJtapiProperties

Message Sequences

No impact.

Backward Compatibility

This feature is backward compatible. JTAPI, including secure providers, runs exactly as they do today, if the application does not specify that they wish to run in FIPS-compliant mode. This choice is deliberate; applications unaffected by FIPS compliance do not interact with FIPS compliance. No changes are required on the applications’ part.

Applications that want to operate in a FIPS-compliant mode has to explicitly request it when downloading certificates with JTAPI, and when opening a provider. In addition, applications are required to download supplementary cryptographic libraries (jar files) from the Unified CM server, and modify their classpath accordingly to include them before the jtapi.jar library.

Forced Authorization and Client Matter Codes

Forced Authorization Codes (FACs) force the user to enter a valid authorization code prior to extending calls to specified classes of dialed numbers (DN), such as external, toll, or international calls. Authorization information is written to the Cisco Unified Communications Manager CDR database.

Client Matter Codes (CMCs) let the user enter a code before extending a call. Customers can use Client Matter Codes for assigning accounting or billing codes to calls that are placed, and Client Matter Code information is written to the Cisco Unified Communications Manager CDR database.

Supported Interfaces

Cisco Unified JTAPI supports FAC and CMC in the following interfaces:

  • Call.Connect()

  • Call.Consult()

  • Call.Transfer(String)

  • Connection.redirect()

  • RouteSession.selectRoute()

Call.Connect() and Call.Consult()

When an application initiates a call with one of these interfaces to a DN that requires an FAC, CMC, or both codes, CiscoToneChangedEv is delivered on a CallObserver that also contains which code or codes are required for the DN. The getCiscoCause() interface returns CiscoCallEV.CAUSE_FAC_CMC for this even if it is delivered because of FAC_CMC feature. The getTone() interface returns CiscoTone.ZIPZIP to indicate that a ZIPZIP tone played.

Upon receiving the CiscoToneChangedEv, applications need to enter the appropriate code or codes by using the connection.addToAddress interface with a # terminating string. Digits either can be entered one at a time within the interdigit timer value (T302 timer) for each digit including the # terminating character, or all the digits, including the # termination character, can be entered within the T302 timer value that is configured in Cisco Unified Communications Manager Administration.

When FAC and CMC Are Both Required

For a DN that requires both codes, the first event is always applies for the FAC, and the second code applies for the CMC, but the application can send both codes, separated by a pound sign (#), in the same request. The second event remains optional, based on what the application sends in the first request.

The application can send both codes at the same time, but both codes must end with #. as shown in the following example:

connection.addToAddress("1234#678#")

where 1234 represents the FAC and 678 specifies the CMC.

In this case, the application does not receive a second CiscoToneChanged.

The first CiscoToneChangesEv will have getWhichCodeRequired() = CiscoToneChanged.FAC_CMC_REQUIRED, and getCause() = CiscoCallEv.CAUSE_FAC_CMC.

In response, one of the following cases can occur:

  • The application sends FAC and CMC in the same connection.addToAddres(code1#code2#) request. In this case, no second CiscoToneChangedEv gets sent to the application.

  • The application sends only a FAC code in connection.addToAddress(code#1). In this case, the application receives a second CiscoToneChangedEv with getWhichCodeRequired() = CiscoToneChangedEv.CMC_REQUIRED.

  • The application sends only part of the first code or the complete first code and incomplete second code (if the code is not terminated with #, it remains is incomplete and the system waits for the T302 timer to expire and tries to validate the code). If the code is incomplete, a second CiscoToneChangedEv tone gets generated with getWhichCodeRequired() = CiscoToneChangedEv.CMC_REQUIRED and getCause() = CiscoCallEv.CAUSE_FAC_CMC.

PostCondition Timer

The PostCondition timer resets each time that the connection.addToAddress interface is invoked to send code. FAC and CMC must have the terminal # [for example, Connection.assToAddress("1234#"), where 1234 is the FAC]. The system waits for the T302 timer to expire, then extends the call if all codes have been entered. If all codes have not been entered, the system plays reorder tone. In this case, the application could receive PlatformException with postConditionTimeout even if the call is extended. To avoid this, the application needs to increase the postcondition timeout by using JTAPI Preferences.

If the application uses call.connect() or call.consult() to initiate a call, but the FAC or CMC (including #) is not entered from a Cisco Unified IP Phone within the postcondition timeout limit, the request could get a platformException with postCondition timeout, but the call may actually get extended. To avoid this, the application needs to increase the postcondition timeout by using JTAPI preferences.

Shared Lines

If the initiating party is a shared line, applications need to use setRequestController to set active terminalConnection before passing additional digits by using the connection.addToAddress interface.

Invalid or Missing Codes

If a code is invalid or no code is entered before the T302 timer expires, the call gets rejected with callCtlCause cause code as CiscoCallEv.CAUSE_FAC-CMC.

Call.transfer(String) and Connection.redirect()

Two additional string parameters (facCode, cmcCode) are added to these interfaces to support FAC and CMC. The default value for these codes represent null values.

No CiscoToneChangedEv gets delivered for these requests for DNs that require codes. A call that is conditionally redirected to a DN, a FAC, a CMC, or both, does not get rejected but remains connected if either code is incorrect.

RouteSession.selectRoute()

Two additional arrays of string parameters (facCode, cmcCode) support FAC and CMC. For each routeselect element, applications can specify the code for the DN. Applications need to specify null values for DNs that do not require any codes. The default values for the codes are null values.

If one routeselected element does not contain the correct code, the next element in the arrays gets tried. If all of them fail, reRouteEvent gets sent to the application.


Note


The system does not support forwarding to a DN that requires an FAC or CMC code. The application can set the forward number to these DNs by using the Address API, but calls forwarded to these numbers are rejected.


Forwarding on No Bandwidth and Unregistered DN

This feature enhances the forwarding logic to handle the No Bandwidth & Unregistered DN cases:

  • No Bandwidth: When a call cannot be delivered to a remote destination due to no bandwidth, the system reroutes the call to the AAR Destination Mask or voice mail. The user makes these configuration changes from the directory number window of the Cisco Unified Communications Manager GUI.

  • Unregistered DN: When a call is placed to an unregistered DN, the system delivers the call to a DN that is configured for Call Forward on No Answer (CFNA).

When a call is forwarded due to Call Forward No Bandwidth (CFNB) to another cluster destination over a trunk/gateway that is using QSIG, call history might get lost. For example, if Phone A calls Phone B, which is in a low bandwidth location, with CFNB set to forward calls to Phone C, which is in a different cluster, and the QSIG protocol is used for this intercluster forwarding, then the original called party and the last redirecting party might not get passed to the destination party.

GetCallID in RTP Events

GetCallID provides an interface on RTP events to access any call information, such as calling party or called party, so applications can link RTP events with the calls.

The callLegID that is received in the RTP events from CTIManager gets used to determine the ICCNCall on the client side. This call passes on to the JTAPI layer, and the CiscoCall gets determined, from which CiscoCallID is obtained. This information gets used to construct the RTP events that are delivered to the application.

The following interface gets added to CiscoRTPInputStoppedEv, CiscoRTPInputStartedEv, CiscoRTPOutputStoppedEv, and CiscoRTPOutputStartedEv:

{ public CiscoCallID getCallID();

}

GetCallInfo

GetCallInfo interface on address provides applications with the ability to query CallInfo on an address. A query returns the CiscoAddressCallInfo object, which contains information about the number of active or held calls, maximum number of active or held calls, and the call object for current calls on the address. This interface also specifies what calls are at a specific address at a specific time.

Use the following interface to get information about calls that are present at the terminal:

{ public CiscoAddressCallInfo getAddressCallInfo(Terminal iterminal);}

GetGlobalCallID

GetGlobalCallID provides an interface on the CiscoCallID to get the nodeID and the Global Call ID (GCID) of the call; this exposes the GCID information that is available in the internal call object.

The following methods get added to the CiscoCallID interface:

{    /**
     * returns the callmanager nodeID of the call
     */
public int getCallManagerID();

     /**
     * returns the GlobalCallID of the call
     */
public int getGlobalCallID ();
}

}

Hairpin Support

A hairpin call happens when the call leaves one cluster to some other device across the gateway, then comes back to a device in the same cluster. The GCID for the call coming back into the cluster would differ from the GCID that originally initiated the call, even though both are in the same cluster. In previous releases, if JTAPI controlled both parties, there were two connections: one for CiscoAddress.Internal and the other for CiscoAddress.External.

JTAPI supports hairpin calls when an application monitors both ends of the hairpin call. Previously, only one end of the hairpin call could be monitored because the address was represented only as a DN.

In the current release, if two addresses exist with the same DN but one is within the same cluster and the other is across the gateway, JTAPI creates a separate address object for the external DN, and only one connection is returned for an address, based on its type. This process avoids hairpin issues, as in previous releases when the address was represented only as a DN and when an application retrieved connections for the address it used to get two connections.

Since fixing these issues could have caused compatibility issues with previous releases, a generic solution for these issues was developed in this release. Calls that involve an external party with the same DN as the monitored local party are now properly supported; however, no new interface is added for this feature.

Backward Compatibility

This feature is not backward compatible.

Half-Duplex Media Support

Currently JTAPI media events CiscoRTPInputStarted, CiscoRTPOutputStarted, CiscoRTPInputStopped and CiscoRTPOutputStopped do not indicate whether media is half duplex (receive only / transmit only) or full duplex (both receive and transmit).

This enhancement adds the capability to provide this information in a JTAPI media event. JTAPI provides an interface on the above media events to query whether media is half duplex or full duplex.

The half duplex media support feature does not impact JTAPI backward compatibility.

A new interface getMediaConnectionMode() is added to Cisco Unified JTAPI RTP events. This interface will return the following values depending on the media:

  • CiscoMediaConnectionMode.NONE

  • CiscoMediaConnectionMode.RECEIVE_ONLY

  • CiscoMediaConnectionMode.TRANSMIT_ONLY

  • CiscoMediConnectionMode.TRANSMIT_AND_RECEIVE.

CiscoRTPInputStarted/StoppedEv should only return RECEIVE_ONLY and TRANSMIT_AND_RECEIVE. The interface should not return NONE or TRANSMIT_ONLY. Ifthat happens, applications should ignore the event or log an error.

CiscoRTPOutputStarted/StoppedEv should only return TRANSMIT_ONLY and TRANSMIT_AND_RECEIVE. The interface should not return values NONE or RECEIVE_ONLY. Ifthat happens, applications should ignore the event or log an error.

CiscoMediaOpenLogicalChannedEv should only return RECEIVE_ONLY and TRANSMIT_AND_RECEIVE. The interface should not return values NONE or TRANSMIT_ONLY. Ifthat happens, applications should ignore the event or log an error.

Hold Reversion

The Hold Reversion feature provides applications with a notification when Cisco Unified Communications Manager notifies an address about the presence of a held call, when the call has been ONHOLD for a certain amount of time. Applications receive this notification as the CiscoCallCtlTermConnHeldReversionEv call control terminal connection event on their call observers on the particular address that has put the call ONHOLD. This notification is provided only once for the applications for the held call.

The event is sent only to the terminal connection of the terminal where the call was put on hold. If the address represents a shared line address, other terminal connections of the shared line address will not receive the event.

To receive this event, applications must add a call observer to the address. The cause for this event will be CAUSE_NORMAL. If the call observer is added after the hold reversion timer has expired and the notification has already been sent to the phone, applications will receive CiscoCallCtlTermConnHeldReversionEv with cause CAUSE_SNAPSHOT.

For more information, see CiscoCallCtlTermConnHeldReversionEv.

Hunt List

This feature enables the JTAPI application to observe addresses and terminals that are HuntList LineGroup members. Calls can arrive at these addresses either by another address calling it directly or through HuntPilot. When a call is made to HuntPilot, JTAPI creates a CiscoHuntConnection to represent HuntPilot and provides a Call Model that gives applications the information that the call is routed through HuntPilot. When a call is routed through HuntPilot and is connected to LineGroup Member, JTAPI call has three connections, two regular connections for calling and called addresses, and one CiscoConnection to HuntPilot through which that call was routed.

HuntPilot is not an observable address. The address representing Hunt Pilot is created when a call is made to a Hunt Pilot and is removed when the call is over. Applications cannot receive the Hunt Pilot address from the provider by using the getAddress() method.

In normal Hunt List calls, there are three connections, Calling, Hunt Pilot, and Hunt Member. When a call is made to the Hunt Pilot Directory Number, the call is offered to one of its members depending on the algorithm. The initial state of the call is Offering at the member. If members are not observed, the connection to Hunt Pilot goes through the normal states as CallCtrlConnection or Connection. If members are observed, connection to member goes to Offering state and the connection to Hunt Pilot goes to Established state. Applications must use the states of the observed party to track the state of the call.

call.getCurrentCalledParty() for a call to Hunt Pilot returns an address of type CiscoAddress.HUNT_PILOT. If the Hunt List member is the called address and is not observed by the application, connection to the member is created only when the call is answered.

CiscoHuntConnection extends CallControlConnection and can get into states that a call control connection could transition to expect for the network states.

Hunt pilots are represented by CiscoAddress objects and getType () would return CiscoAddress.HUNT_PILOT.

Only addresses returned for Cisocall.getCurrentCalledAddres () and CiscoCall.getCurrentCallingAddress () will have CiscoAddress.HUNT_PILOT type.

When calls to hunt pilot are involved in transfer or conference operations CiscoTransferStartEv, CiscoTransferEndEv, CiscoConferenceStartEv and CicsoConferenceEndEv are not delivered. Applications should use CiscoCallChangedEv to identify surviving call.

If consult calls or final call have CiscoHuntConnection, the application should not expect Transfer or Conference start and end events.

When configured in broadcast mode, all Hunt List members ring simulatenously. In JTAPI, call connections and terminal connections for Hunt List members are created only for members observed by the application.

Applications must enable this feature using the setHuntListFeatureEnabled (boolean) on CiscoJtapiProperties. This feature is disabled by default and applications are encouraged to adapt to the above call model and enable the feature using setHuntListFeatureEnabled () API. Observing a hunt list member without enabling the feature using setHuntListFeatureEnabled () is not a supported configuration and if observed, results in inconsistent call model and events. setHuntListFeatureEnabled() is introduced to enable applications that are currently using unsupported call scenarios with Hunt List to migrate to a supported model without breaking the existing functionality.

Applications can also enable this feature by adding, HuntListEnabled = 1, to jtapi.ini file and restarting the application.

Hunt List Connected Number

In Cisco Unified CM 9.0, the support for hunt pilots is enhanced to expose the connected number as the modifiedCalledAddress in a call involving a hunt pilot.

With this enhancement, when a user calls a hunt pilot and the call is answered by the hunt member L1, call.getModifiedAddress() returns the address of the member L1, whereas call.getCurrentCalledAddress() returns the address of hunt pilot. Before the call is answered, both these values will return the address of hunt pilot.

Backward Compatibility

This feature is backward compatible. To enable this feature, a new Hunt Pilot configuration, "Display Line Group Member DN as Connected Party" is introduced. Application may choose to enable or disable feature based on their requirements. By default, this feature is disabled.

Hunt Log Status

With this feature, the Cisco JTAPI interface includes the ability of a terminal to sign in and sign out of the hunt group through CTI applications. Previously, this functionality was only available from Cisco Unified CM Administration interface.

Once a terminal is logged into a hunt group, it is able to receive calls which are offered on the line group where the line of terminal is associated.

Cisco Terminal is enhanced with two new methods:
  • CiscoTerminal.getHuntLogStatus()

  • CiscoTerminal.setHuntLogStatus()

These two new methods are used to get and set the value of huntLogStatus and the three new constants CiscoTerminal.DEVICE_HUNT_LOGGED_IN, CiscoTerminal. DEVICE_HUNT_LOGGED_OUT and CiscoTerminal. DEVICE_HUNT_NOT_APPLICABLE. The value is CiscoTerminal.DEVICE_HUNT_LOGGED_IN by default for any terminal that has the ability to log in to the hunt group.

A new interface, CiscoTermHuntLogStatusChangedEv, is introduced for applications to be notified with the event CiscoTermHuntLogStatusChangedEv when the value of hunt log status is changed and the filter is set.

CiscoTermEvFilter is enhanced with two new methods: CiscoTermEvFilter. setHuntLogStatusChangedEvFilter(boolean filterValue) and CiscoTermEvFilter.getHuntLogStatusChangedEvFilter() to set and get the value of filter, if the application wants to be notified by the event CiscoTermHuntLogStatusChangedEv the filter should be set to true. The value of filter is false by default.


Note


The above methods are invoked only on devices which have observers added on it and the terminal object is in service.

Intercom

The Intercom feature allows one user to call another user and have the call answered automatically with one-way media from the caller to the called party, regardless of whether the called party is busy or idle. The called user can press the talk back softkey (unmarked key) on their phone display, or the called user can invoke the join() JTAPI API, that is provided on TerminalConnection, to start talking to the caller. Only a specially configured intercom address on the phone can initiate an intercom call. Cisco Unified JTAPI creates a new type of address object named CiscoIntercomAddress for intercom addresses that are configured on the phone. The application can get all the CiscoIntercomAddresses that are present in the provider domain by calling the interface getIntercomAddresses () on CiscoProvider.

An intercom call can be initiated from the Cisco Unified JTAPI interface by calling the CiscoIntercomAddress.ConnectIntercom () interface. The application provides an intercom target DN for this interface. If the intercom target DN is preconfigured or preset by the application, the application can get the target DN by calling the CiscoIntercomAddress.getTargetDN() interface; otherwise, the application must provide a valid intercom target for the call to be successful.

An intercom call is autoanswered at the intercom target; Cisco Unified JTAPI will move TerminalConnection/CallCtlTerminalConnection at the intercom target to the Passive/Bridged state. The application can invoke a join () interface on the TerminalConnection of the intercom target to initiate talk back. If join () is successful, the TerminalConnection/CallCtlTerminalConnection of the intercom target will move to an Active/Talking state. For an intercom call, Cisco Unified JTAPI only supports the following interfaces:

  • Call.drop ()

  • Connection.disconnect ()

  • CallCtlTerminalConnection.join ()

The application cannot perform any feature operations on an intercom call. Cisco Unified JTAPI will throw an exception if the application invokes redirect, consult, transfer, conference, or park for a Connection on a CiscoIntercomAddress. The application will also receive an exception if it tries to invoke setForwarding (), getForwarding (), cancelForwarding (), unPark (), setRingerStatus (), setMessageWaiting (), getMessageWaiting (), setAutoAcceptStatus (), or getAutoAcceptStatus () on CiscoIntercomAddress.

Applications can get the value of a configured intercom target DN and the label on a CiscoIntercomAddress from the provided API. Cisco Unified JTAPI provides two types of APIs: one to return the default and another to return the current value set for the intercom target. The default value is the intercom target DN and label that are preconfigured through Cisco Unified Communications Manager Administration. The current value is the interim target DN and label that the application sets. If the application has not set any value, the current value remains the same as the default value. Applications can invoke the API setIntercomTarget () on CiscoIntercomAddress to set the intercom target DN, label, and unicode label. Only one application can set the intercom target, label, and unicode label for an intercom address. If two applications try to set the value, the first succeeds, and the second receives an exception. When a intercom target DN and label changes, Cisco Unified JTAPI provides a CiscoAddressIntercomInfoChangedEv to the AddressObserver that is added to CiscoIntercomAddress. If the application has set an intercom target DN and label, and a JTAPI or CTI failover or failback occurs, JTAPI or CTI will restore the previously set value of the intercom target DN, label, and unicode label. If the JTAPI or CTI cannot restore the intercom target DN, label, or unicode label, Cisco Unified JTAPI provides a CiscoAddrIntercomInfoRestorationFailedEv to the AddressObserver on CiscoIntercomAddress. In the case of an application failure, or if for any reason the application goes down, the target DN, label, and unicode label will reset to the default. JTAPI provides the interface resetIntercomTarget () on the CiscoIntercomAddress to reset the intercom target.

Auto-answer always stays enabled for CiscoIntercomAddress. The application can invoke the method getAutoAnswerEnabled () on CiscoAddress to get the auto-answer capability of an address.

For an intercom target that is connected with one-way media to the Intercom initiator, the device state would be set to CiscoTermDeviceStateWhisper. This is a new device state for the terminal object. In this state, the terminal can initiate a new call or receive a new incoming call. If the application enables a filter to receive this device state, the application receives CiscoTermDeviceStateWhisperEv. The application can enable a filter by calling setDeviceStateWhisperEvFilter() on CiscoTermEvFilter. The DeviceStates DEVICESTATE_ACTIVE, DEVICESTATE_HELD, and DEVICESTATE_ALERTING all override DEVICESTATE_WHISPER; if one call exists in active, held, or alerting state, and another in whisper, the DeviceState will be DEVICESTATE_ACTIVE, DEVICESTATE_HELD, or DEVICESTATE_ALERTING, respectively.


Note


The Cisco Unified JTAPI implements the javax.telephony.TerminalConnection interface join() to let the intercom target talk back to the initiator. The system implements this interface for CiscoIntercomAddresses only. If applications invoke this interface for regular shared lines in a passive or bridged state, JTAPI throws a MethodNotImplimented exception.



Tip


This feature is backward compatible if the application-controlled devices (terminals) do not have intercom lines configured on them. Applications can disable the intercom feature by not having an intercom line configured on the application-controlled devices (terminals).


For detailed information about these interface changes, see the following topics:

Intercom Support for Extension Mobility

In Release 6.0(1) of Cisco Unified Communication Manager, support for intercom feature was added. Intercom feature requires destination to be auto-answered with one-way audio; therefore, no shared addresses can be configured for intercom. When user logs in by using Extension Mobility (EM) profile, it is possible to end up with shared address for intercom; so, currently extension mobility is not supported with intercom. Due to the wide use of extension mobility, this CIA is addressing the need to support intercom for extension mobility while still maintaining the single destination nonsharable nature of intercom addresses.

This feature requires intercom addresses to be configured with default terminal, and allows configuring of intercom address on EM profile. When EM user logs in to a terminal with EM profile that is configured with an intercom address, intercom address is available only if default terminal of intercom address is same as terminal where user has logged in. If an intercom address is configured on terminal but default terminal for intercom address is not that terminal, intercom address does not appear on terminal. If this terminal is configured in the control list of Cisco Unified JTAPI application, JTAPI does not create intercom address in the provider domain. From Cisco Unified JTAPI point of view, there is no new interface or changes to support this feature. However, this feature introduces some transitional scenarios where intercom functionality may not work on intercom addresses. See the use cases.

Backward Compatibility

This feature is backward compatible.

IPv6 Support

This feature provides support for IPv6 addresses and CiscoUnified JTAPI is enhanced to support IPv6 connectivity to CTIManager. It enables Cisco Unified JTAPI applications to see the IPv6 address as the calling party address if the IPv6 support feature is enabled and if the Calling Party is using an IPv6-enabled phone. This feature support the following functions:

  • Cisco Unified JTAPI exposes new API canSupportIPv6() on the CiscoProviderCapabilities Interface to indicate whether Cisco Unified Communications Manager configuration is supporting IPv6.

  • Cisco Unified JTAPI closes the media or route terminal if there is mismatch between what has been previously registered and what is currently configured. CiscoTermRegistrationFailedEv and the new reason code IP_ADDRESSING_MODE_MISMATCH are then sent as per this scenario.

  • The IP Address capability of the Terminal is exposed by API getIPAddressingMode() on the CiscoTerminal Interface. The IP Address capability is available on CiscoTerminal/CiscoMediaTerminal and CiscoRouteTerminal.

  • The IPv6 calling party IP address is provided through the Cisco extensions of CallCtlConnOfferedEv and RouteEvent in an InetAddress object as well as the IPv4 address for IPv4-enabled devices.

The RTP Address in CiscoRTPOutputStartedEv and CiscoRTPInputStartedEv also has an IPv6 address in case the observed device is an IPv6 device. That is, the API getLocalAddress() on CiscoRTPInputProperties and the API getRemoteAddress() on CiscoRTPOutputProperties can now return an IPv6 format IP Address. The API returns an InetAddress object, and applications can verify that it is an instance of Inet4Address or Inet6Address to determine if it is an IPv4 or IPv6 format IP Address.

Applications must reset the devices after their IP Addressing Mode is changed, otherwise there might be ambiguity in the expected results.

From Release 7.1, Cisco Unified JTAPI provides getIPAddressingMode() API on CiscoTerminal. The getIPAddressingMode() API for CTI Ports and Route Points are also supported from this release.

Cisco Unified JTAPI extends the same API on CiscoTerminal and it returns the configured IP addressing mode of the IP phone on the Cisco Unified Communications Manager Admin pages. If the user modifies the IP Addressing mode from the Cisco Unified Communications Manager Admin pages after the device is registered, the device must be reset. The updated value from Cisco Unified JTAPI is exposed only after the IP phone is reset. If the configured IP Addressing mode supports both IPv4 and IPv6 addresses, the phone may be registered with either of these addresses or with both. This depends on conditions such as network type and Cisco Unified Communications Manager support for IPv6. So, if the IP Addressing mode mode supports both IPv4 and IPv6 addresses, getIPAddressingMode() on CiscoTerminal returns CiscoTerminal.IP_ADDRESSING_MODE_IPV4_V6.

iSac Codec

This enhancement provides support for iSac codec and enables the application to register CiscoMediaTerminal or CiscoRouteTerminal with iSac codec capability. For this codec, frame size and bit rate are variable and determined dynamically. Applications do not set these values.

The bit rate and packetSize that are exposed on interface CiscoRTPInputProperties and CiscoRTPOutputProperties will not be a constant for this codec, so application logic should not rely on these values if codec (payloadType) is iSac.

Java Socket Connect Timeout

The Java Socket Connect Timeout enhancement enables the configuration of a timeout in seconds by using the Cisco Unified JTAPI specification and prevents connection delays to the CTIManager when the primary CTI Manager. The default is 15 seconds.

If the default of 15 seconds is unacceptable to the application, the default JAVA API of zero (0) sets the behavior to the normal JAVA Socket Connect API.

The values range from 5 through 180 seconds. Zero defaults to Java behavior of the socket connect without any time-out for connection.

Join Across Lines

In this version, this feature allows applications to conference two calls that are on different addresses of the same terminal. It will also let applications add participants to a conference using a noncontroller. Join across lines is not supported on CTI-supported phones that run SIP.

You can disable join across lines feature by turning off Join Across Lines Policy service parameter, while you can disable Conference Chaining and feature to allow noncontroller adding participant to conference by disabling the "Advanced Ad Hoc Conference Enabled" and "Non-linear Ad Hoc Conference Linking Enabled" service parameters.


Note


Join Across Lines is supported only on phones that run SCCP.


Interface Changes

There are no interface changes for this feature. Applications can use the current conference interfaces to conference calls on different addresses on the same terminal.

Backward Compatibility

This feature is backward compatible.

Join Across Lines (Only SCCP)

The Join Across Lines feature allows support for conference across lines. It allows two or more calls on different addresses of the same terminal to be joined though the join softkey on the phone or conference() API that JTAPI provides. The behavior to JTAPI applications change, as applications do not perceive a common controller in final and consult calls.

There is no change in the API and the same events are delivered whether calls are conferenced on the same address (regular conference) or across addresses (Join across lines). When join across lines feature is performed CiscoConferenceStartEv/EndEv will be provided to all addresses on the controller terminal that have consult or final calls that are being joined together into one conference.

In CiscoConferenceStartEv, the conferenceControllerAddress will always be the primary controller address. Application can now set the controller via the setConferenceController() API. If application does not specify this, then JTAPI itself would find a suitable controller for the conference. Cisco recommends that applications set the controller address when Join Across Lines feature is invoked.

If observer is not added on the controller address, applications may see null values for either the talking or held terminal connection values in the CiscoConferenceStartEv. Before this release, when application tried a conference across lines, the request failed at the JTAPI layer itself. With this release, the conference() API implementation enhances all requests to pass through after finding suitable terminal connections of the final and consult calls. JTAPI relies on the common terminal of the addresses involved in the call to find suitable terminal connections. Multiple conference across address is also supported when more than two calls need to be joined. SIP devices in 5.1.2 release do not support this feature. JTAPI throws exception (ILLEGAL_HANDLE) if this feature is requested on a SIP device.

There are no interface changes for this feature. Behavior changes with respect to events provided to applications.

Backward Compatibility

This feature is backward compatible, as there are no changes in the behavior of conference when this feature is not enabled. You can enable or disable this feature on a per-device basis. If the Join Across Lines setting on the device is set to Default, the system-wide CallManager service parameter Join Across Lines Policy setting is used. If this feature is enabled and application does a join across lines, there is a difference in behavior as stated.

JTAPI applications written for Release 5.1 should be backward compatible with JTAPI that was released with Release 5.1.2. Consider a JTAPI client upgrade only if new features are used.

Join Across Lines or Connected Conference Across Lines

User experience is enhanced in this release by introducing Cisco Unified IP Phone models that fall outside the purview of existing Join Across Lines service parameter. For these phones this feature is always enabled, without any service parameter to turn it off. For a detailed feature description, information about interface changes, and use cases, see Join Across Lines with Conference Enhancements (SCCP and SIP).

Usage Guidelines

The points below indicate how applications must use the Direct Transfer Across Lines feature:

  • Applications must add Call Observer on the both the lines across which they try join across lines or connected conference.

  • Earlier, applications were recommended to check if both the calls have a common address and if that common address is on the same Terminal. For Join Across Lines, it is not required to check if the address is comoomon between two calls across which direct conference is invoked. It must be ensured that both the calls should each have an address that exists in common terminal.

  • Cisco Unified JTAPI reports the same set of events, as it does currently, for conferencing of calls on the same address. Applications are not required do anything with these calls after invoking Conference() until receiving CiscoConferenceEndEv.

  • As conference is done across addresses, applications do not get a common controller in CiscoConferenceStartEv and should upgrade the application logic. See Event Flow Comparison and Sample Code for details.

Note

 

Application logic is based on common transferControllerAddress and works fine in this case, because commonAddr is present in both final and consult call

Note

 

There is no common address for controllers in final and consult call, but the controller TerminalName is same for both the controller addresses. So, application should rely on CommonTerminalName to find out the connections, terminal connections and controllers.


Note


In connected Conference Across Lines scenario, apart from the events mentioned, applications can see another temporary call GC3 going active(CallActiveEv) and GC3 goes idle (CallInvalidEv) immediately after the conference is completed.

Backward Compatibility

This feature is backward compatible.

This feature cannot be turned off for certain devices and Cisco Unified JTAPI always reports events for Join Across Lines for these phones. However, to provide backward compatibility for applications, a new permission to allow controlling these devices and to allow connected conference across lines has been added. A new standard role Standard CTI Allow Control of Phones supporting Connected Xfer and conf and a standard user group are also added. Applications can control these devices only if this new role is associated to the application user, assuming that application is using JTAPI client 7.1.2 or higher. So, by default these devices are listed as Restricted. The application must upgrade to handle this feature and associate the new permission to control these devices. If the application uses an older JTAPI client the devices are not restricted but if the application tries to observe these devices (which supports this feature to be invoked manually), JTAPI throws an exception and marks these devices as restricted from there on.

Cisco assumes that two or more applications do not control or observe the same terminal or address simultaneously. If they do, all instances of this application make changes to support this feature or coordinate to avoid any problem. Otherwise, application behavior may be unforeseen. For example, if App1 and App2 are two applications controlling or observing the same terminal or address and App1 makes changes to support this feature then App2 is also expected make changes to support the feature. Else, invocation of this feature by App1 on common devices can break App2.

As, the feature is designed to provide an enhanced user experience, Cisco strongly recommends that all Cisco Unified JTAPI applications should evaluate and support this feature and upgrade if necessary with the code logic to handle both the old and new behavior.

Join Across Lines with Conference Enhancements (SCCP and SIP)

Join Across Lines feature supports on CTI-supported SIP phones and SCCP phones. The enhancements are:

  • Applications can conference two calls in which each conference is on a different address but on the same terminal.

  • Add participants to a conference using a non-controller.


Note


You can disable Join Across Lines by turning off the Join Across Lines Policy service parameter. Conference Chaining and the feature that allows Non-Controller adding participant to conference can be disabled by disabling the Advanced Ad Hoc Conference Enabled and Non-linear Ad Hoc Conference Linking Enabled service parameters.


The following behavior occurs when an application issues a conference request, but selected and active calls are not part of the conference request. It also applies for user-selected calls that are not part of the conference request, but become part of the resulting conference:

  • The Active Call on a Terminal is always added to the resulting conference when conference is invoked on a call on any address on that terminal. Consider that B1 and B2 addresses exist on the same terminal, then:

    • A --> B1- GC1

    • C --> B1- GC2

    • D --> B2- GC3 (active call)

    The application invokes GC1.conference (GC2) and results in A-B1-C-D in a conference with GC1, although the call with D was not part of the conference request.

    An active conference call on a terminal is added to the resulting conference when conference is invoked on a call on any line on that terminal. In this case, the active conference call becomes the surviving final call (provided the application-specified primary call is not a conference call).

    In this example, the application specified primary call is cleared after the conference operation. It is possible that the application-specified primary call may not join the resulting conference and in that case the call is not cleared after the conference is complete.

  • Consider that the B1 and B2 addresses on the same terminal and conf1 is a conference call with A-B1-C in conference with B1 as the controller, then:

    • B1 --> D – GC1 (on hold)

    • conf1 – GC2 (active call)

    • B2 --> E – GC3 (on hold)

    Application invokes GC1.conference(GC2, GC3). This results in A-B1-C-D-E in conference with GC2 as the surviving call. Although application had specified GC1 to be the primary call, GC1 does not survive after the conference.

The behavior also applies to regular conferencing with a common controller. Consider A, B, C, and D are lines on different terminals, then:

  • A --> B - GC1

  • C --> - GC2

  • D --> - GC3 (active call)

The application requests GC1.conference (GC2). This results in A-B-C-D in conference with GC1. Although a direct call with Dwas not part of the conference request, D joins the conference.

Backward Compatibility

This feature is backward compatible.

JRE 1.2 and JRE 1.3 Support Removal

This release of the CiscoJTAPIClient supports only JRE 1.4. There are no interface changes; however, the JRE 1.2 and 1.3 versions are no longer supported. This change is to support QoS, which is available only in the JDK1.4 version (and above). Inaddition, jtapi.jar contains Cisco encryption files that depend on the JRE 1.3 version (and above). This provides a stronger password encryption algorithm when it is sent over TCP to CTIManager. As part of this feature, JTAPI invokes the API provided by IMS (Identity Management System, a Cisco Unified Communications Manager component) to encrypt a password before sending it.

JRE 1.4 also enables Cisco Unified JTAPI to use additional JDK 1.4 APIs. Applications that use previous versions of JRE must install JDK 1.4 to use Cisco Unified JTAPI.


Note


There are no interface changes to JTAPI Applications, however JTAPI.jar contains RSA jsafe.jar (3.3) and Apache log4j-1.2.8.jar files. If Applications are using any jar files that are not compatible with these versions of jsafe.jar (Version 3.3) and log4j-1.2.8.jar, then JTAPI or the Application may not work, depending on which one is in the classpath first


As part of this migration, JTAPIPreferences and sample applications dependency on MS-JVM was also removed. Two new configuration parameters were provided on the Advanced tab in the JTAPI Preferences dialog box:

  • JTAPI Post Condition Timeout

  • Use Progress As Disconnected

    Backward compatibility

This feature is not backward compatible.

JTAPI Version Information

In order to connect to Release 5.0 of Cisco Unified Communications Manager Administration, JTAPI clients have to upgrade to the new version of JTAPI bundled with the Cisco Unified Communications Manager Administration Release 5.0. JTAPI version is in the form of 3.0(X.Y), where X and Y depend on the sub-release. Applications cannot connect with prior release of JTAPI.

Locale Infrastructure Development

This feature removes currently supported languages for Cisco Unified JTAPI client install. Cisco Unified JTAPI client install is only supported in English. It also adds the capability to dynamically update the locale in JTAPI Preference application from the Cisco Unified Communications Manager server. JTAPI Preference application will continue to support all the languages that are supported in prior releases. Support for adding new languages and updating locale files is also added.

Before this release, the Cisco Unified JTAPI client install and JTAPI Preferences application were localized during builds and did not add support for new languages or update locales for existing languages. The JTAPI client locale updates were performed in Cisco Unified Communications Manager maintenance releases. This feature adds capability to dynamically update locale file for JTAPI Preferences application, and JTAPI Client install is installable only in English languages.

The JTAPI Client install needs the Cisco Unified Communications Manager TFTP server IPaddress. The TFTP IP address is used for downloading locale files for the preferences application. If the TFTP IP address is not entered or an incorrect IP address is entered, the preference application displays only in English language. Further on, whenever new locale updates are available, JTAPI Preferences application will notify user about available updates and update locale files.

Backward Compatibility

Media Termination at Route Point

This feature enables multiple active calls at the route point, and applications can terminate media for all active calls by specifying the IP address and port number for each call or whenever media is established.

To use this feature, applications must register the route point by supplying media capabilities. When a call gets answered at this route point, CiscoMediaOpenLogicalChannelEv gets sent to the applications. This event gets sent whenever media is established. Applications must react to this event and specify the IP address and port number where they want to terminate media.

A CiscoRouteTerminal represents a special kind of CiscoTerminal that allows applications to terminate RTP media streams. Unlike a CiscoTerminal, a CiscoRouteTerminal does not represent a physical telephony endpoint, which is observable and controllable in a third-party manner. Instead, a CiscoRouteTerminal represents a logical telephony endpoint, which may get associated with any application that intends to route calls and also terminate media. Unlike CiscoMediaTerminal, CiscoRouteTerminal can have multiple active calls at the same time. Typically, CiscoRouteTerminals get used to place calls in queue until an agent is available to service the caller.


Note


Only RoutePoint Terminals appear as CiscoRouteTerminal through JTAPI.


Terminating media comprises a three-step process.

  1. The application registers its media capabilities with this terminal by using the CiscoRouteTerminal.register method.

  2. An application adds an observer that implements CiscoTerminalObserver interface by using the Terminal.addObserver method.

  3. The application must add addCallObserver on CiscoRouteTerminal or on CiscoRouteAddress to receive CiscoCall object from the provider by using CiscoRTPHandle.

Applications receive CiscoMediaOpenLogicalChannelEv for each call and must supply the IP address and port number by using the setRTPParams method on CiscoRouteTerminal.

You must modify applications that are written for the CiscoJtapiClient 1.4(x) release or earlier to register with CiscoRouteTerminal. NO_MEDIA_TERMINATION if the applications are not interested in media termination.

Multiple applications can register with the same route point as long as they are registered with the same media capabilities and registrationType. All applications, if they have registered with CiscoRouteTerminal.DYNAMIC_MEDIA_REGISTRATION and then add a terminal observer, receive CiscoMediaOpenLogicalChannelEv, but only one application can invoke setRTPParams.


Note


Applications that terminate media must use the CallControl package for answering and redirecting calls. Applications that only route calls can use a routing package.



Note


Applications should be aware that, if any features are performed before reacting to CiscoMediaOpenLogicalChannelEv, the features may fail. If applications do not respond to these events in the time that is specified in the Media Exchange Timeout parameter in the Cisco Unified Communications Manager Administration windows, the call may fail.


The following new or changed interfaces exists for Media Termination at Route Point:

Interface CiscoRouteTerminal Extends CiscoTerminal

boolean

isRegistered()

If the CiscoMediaTerminal gets registered, this method returns true. Otherwise, it specifies false.

boolean

isRegisteredByThisApp()

If the application issues a successful registration request, this method returns true and remains true until the application unregisters the device. This remains valid even if the device is out of service because of CTIManager failure.

void

register (CiscoMediaCapability[] capabilities, intregistrationType)

The CiscoRouteTerminal must exist in the CiscoTerminal.UNREGISTERED state, and the provider must exist in the Provider.IN_SERVICE state.

void

setRTPParams (CiscoRTPHandle rtphandle, CiscoRTPParams rtpParams)

Applications set the ipAddress and the RTP port number to dynamically stream media for a call.

void

Unregister()

Ensure the CiscoRouteTerminal is registered, and the provider is in the Provider.IN_SERVICE state.

Interface CiscoMediaOpenLogicalChannelEv Extends CiscoTermEv

int

getpacketSize ()

Returns the packet size of the far end in milliseconds.

int

getPayLoadType ()

Returns the payload format of the far end, one of the following constants:

CiscoRTPHandle

getCiscoRTPHandle ()

Returns the CiscoTerminalConnection object on which applications must invoke the setRTPParams request.

Interface CiscoRTPHandle

int

getHandle()

Returns an integer representation of this object, currently the Cisco Unified Communications Manager CallLeg ID.

CiscoProvider

CiscoCall

getCall (CiscoRTPHandle rtpHandle)

Returns the call object with the rtpHandle that is associated with a specific terminal. If no callobserver gets added to the terminal at the time when the applications receive CiscoRTPHandle in CallOpenLogicalChannelEv, CiscoCall may register null.

For details on these interfaces, see Cisco Unified JTAPI Extensions To view the message flow for media termination at route point, see Message Sequence Charts

Media Termination Extensions

The media termination feature allows applications to transmit and capture the bearer of a call, for example, audio or video. This action sometimes gets referred to as "rendering and recording" or "sourcing and sinking" media. It remains distinct from call control because media termination concerns the data that flows between endpoints in a call, not the details of setting up or tearing down calls. For example, an automatic call distributor (ACD) uses call control to route calls among available agents but does not terminate media. An interactive voice response (IVR) application, on the other hand, uses call control to answer and disconnect calls and uses media termination to play sound files to callers.

Although no telephony applications are solely interested in media termination, this feature always gets used in combination with call control. JTAPI 1.2 primarily represents a call control specification and offers very limited support for applications that require media termination. Because the Cisco Unified Communications Solutions platform supports media termination to a much greater degree than JTAPI standard, the Cisco Unified JTAPI implementation extends JTAPI to add full support for this feature.

In Cisco Unified JTAPI, software-based media termination occurs by using Computer Telephony Integration (CTI) ports. They include one or more lines (dialable numbers) that can be used to originate or receive calls. They however need a controlling application to provide the source and sink of the media. An application registers its interest in the media termination port with the Cisco Unified Communications Manager. The Cisco Unified Communications Manager then delivers all the events that relate this virtual device to the application. InCisco Unified JTAPI, CTI ports get referred to as CiscoMediaTerminals. The following figure shows the CTI port configuration. For details about administering and configuring a CTI port, refer to the Cisco Unified Communications Manager Administration information.

Figure 5. CTI Port Diagram


To implement a softphone application (where the PC acts as the telephone set, for example), the Cisco Unified JTAPI application would manage a CTI port.

Message Waiting Indicator Enhancement

The Enhanced Message Waiting Indicator (MWI) feature enables applications to provide the following message counts to be displayed on phones that support the enhanced message waiting counts:

  • Total number of new voice messages (includes normal and high priority messages)

  • Total number of old voice messages (includes normal and high priority messages)

  • Number of new high priority voice messages

  • Number of old high priority voice messages

  • Total number of new fax messages (includes normal and high priority messages)

  • Total number of old fax messages (includes normal and high priority messages)

  • Number of new high priority fax messages

  • Number of old high priority fax messages

Two new APIs are added as CiscoAddress JTAPI extensions to provide the enhanced MWI message summary information. Similar to the existing setMessageWaiting APIs, one of the APIs allows summary information to be set up for the observed address. The other API allows message summary information to be set up on any address that is reachable on the observed address, as defined by the configured calling search space of the observed address.

These new APIs can also be used on phone types that do not support the enhanced message counts. If used on non-supported phones, these APIs behave similar to the existing setMessageWaiting method, that is, only the messaging waiting indicator lamp is turned on or off and counts are not displayed.

Interface Changes

See Related Documentation

Message Sequences

See Enhanced MWI Use Cases

Backward Compatibility

This feature is backward compatible. The existing setMessageWaiting APIs will not be modified. Applications that do not want to use the new enhanced MWI feature can continue to use these APIs for setting the MWI lamp.

Modifying Calling Number

This feature enables applications to modify the calling party DN in the select route API from the route point. Applications may pass an array of modifying calling numbers in the selectRoute API and an array length of modifying calling numbers may equal the length of the route that is selected. If no modifying calling number element is present for a corresponding routeSelected index or if the element is null, then no modifying calling number gets set for that route selected element.

Two new interfaces getModifiedCallingAddress () and getModifiedCalledAddress () are exposed on the call object, which returns modified calling or called number. If no modification occurs, these interfaces may return the same values as getCurrentCallingAddress () and getCurrentCalledAddress () interfaces. If an application is only controlling the route point and modifies the calling number by using selectRoute API, it may not get modified calling address in the getModifiedCallingAddress interface. If an application is controlling any calling or called parties, it may get correct values after it receives call control events after the calling number is modified.

A new interface, getRouteSelectedIndex (), gets exposed on the new class CiscoRouteUsedEvent, an extension of RouteUsedEvent, which gives the index of the selected route. Applications need to cast the RouteUsedEvent to the CiscoRouteUsedEvent to get access to this method.

Example


routeSelected[0]  =  133555 
routeSelected[1]  =  144911 
routeSelected[2]  =  143911 
routeSelected[3]  =  5005  

modifiedCallingNumber[0]  = null
modifiedCallingNumber[1]  = 9721234567
modifiedCallingNumber[2]  = 9721234568
modifiedCallingNumber[3]  = null

If routeSelected[0] or routeSelected[3] is selected for routing, the modifying calling number may not get applied.

You can only use this feature after an administrator enables the modifying calling number check box in the Cisco Unified Communications Manager Administration for a particular user, which by default is False. If it is not configured, a RerouteEvent with the cause of RouteSession.CAUSE_PARAMETER_NOT_SUPPORTED gets sent to the applications. The application that is modifying the calling number needs to be aware that display name on the called party is affected, and subsequent feature interactions of the calling or called party may result in inconsistent behavior.

The following new or changed interfaces exist for Modifying Calling Number:

CiscoRouteSession

void

selectRoute (java.lang.String[] routeSelected, intcallingSearchSpace, String[] modifiedCallingNumber)

This interface allows applications to modify the calling party number to the routeSelected address. If no modifiedCallingNumber element exists for the corresponding routeSelected element, the calling number does not get modified if a call gets routed to that particular routeSelected element.

CiscoCall

javax.telephony.Address

getModifiedCalledAddress ()

This interface returns a modified called address for the call if an application modifies the calling party by using the selectRoute API; however, this information may not be accurate if an application is only controlling the route point that modifies the calling number. If no modified calling number gets performed, this acts similar to the getCurrentCalledAddress interface. Typically, this gets varied from getCurrentCalledAddress when a feature gets invoked after modified calling number modifications.

javax.telephony.Address

getModifiedCallingAddress ()

This interface returns a modified calling address for the call if an application modifies the calling party by using the selectRoute API; however, this information may not be accurate if an application is only controlling the route point that modifies the calling number. If no modified calling number gets performed, this interface acts similar to the getCurrentCallingAddress interface.

CiscoRouteUsedEvent

int

getRouteSelectedIndex()

This method returns an array index of the route to where the call gets routed.

Multi-fork Recording using CUBE Media Proxy Server

Prior to Cisco Unified Communications Manager, Release 12.5(1), the Unified Communications Manager supported only single recorder for a call. With the Cisco Unified Communications Manager, Release 12.5(1), the Unified Communications Manager supports Multi-forking for Call Recording feature.

The Unified Communications Manager is connected to CUBE Media Proxy server which is connected to multiple recorders. The JTAPI interface is enhanced to get the details of multiple recorders in case of Multi-Forking recording through CUBE Media Proxy server.

Backward Compatibility

This feature is backward compatible. JTAPI supports the current APIs.

Multilevel Precedence and Preemption Support

Cisco Unified Communications Manager enables the use of supplementary services by phones that are configured for Multilevel Precedence and Preemption (MLPP). Cisco Unified Communications Manager does this by maintaining the precedence level for calls.


Note


JTAPI does not provide the precedence level of applications.


Multiple Calls Per DN

Multiple calls per DN represent the ability to support multiple calls on a line (DN) and the features operation on these calls. Prior to Cisco Unified Communications ManagerRelease4.0(1), the system supported a maximum of only two calls. Cisco JTAPI now supports multiple calls per line, which allows multiple calls on the same line and feature operation on that line.

No interface or message flow changes occurred for Multiple Calls Per DN.

Native Queuing

It is very common in a Cisco Unified CM deployment that a hunt pilot has more calls distributed through the call distribution feature than its hunt members can handle at any given time. Native Queuing feature holds the calls in a queue until they are answered. When a hunt member is available, the call is removed from the queue and offerred to the hunt member.

To enable this feature, the Cisco Unified CM administrator needs to enable the check box Queue Calls in Queuing section of the Hunt Pilot configuration page. Following settings are available under Native Queuing feature configuration:

  • Maximum Number of Callers Allowed in Queue (1–100): This is the queue depth configuration and reflects the maximum number calls that can be in the queue at any point of time.

    • Destination When Queue is Full: User Configurable Destination number to which the calls are forwarded when the Maximum Number of callers allowed in queue limit is reached.

    • Disconnect: This option results in the call getting rejected and dropped when the Maximum Number of callers allowed in queue limit is reached.

  • Maximum Wait Time in Queue (10–3600 seconds): User configurable Maximum wait time a call can be in the queue.

    • Destination When Maximum Wait Time is met: User Configurable destination DN to which the call is forwarded when the maximum wait time in queue is reached.

    • Disconnect: This option results in the call getting rejected and dropped when the the maximum wait time in queue is reached.

  • When There Are No Hunt Members Logged In or Registered: User configurable destination DN to which the queue feature forwards the calls when none of the hunt members in the HuntPilot are registered or logged in.

    • Disconnect: This option results in the call getting rejected and dropped when there are no hunt members available for the dialed hunt pilot.

    • Destination: User Configurable destination DN to which the call is forwarded when no hunt members available for the dialed hunt pilot.

If a caller calls a hunt pilot with all its members busy, a CiscoHuntConnection will be created temporarily. Then, when this feature is enabled, the hunt connection will drop and a new connection will be created which will have the address name same as that of the hunt pilot and the address type will be CiscoAddress.INTERNAL. This new connection will be moved to CallControlConnection.QUEUED state and it will remain in this state until the call gets dequeued or dropped.

Cisco JTAPI exposes the following new reasons:

  • CiscoFeatureReason.REASON_QUEUING

  • CiscoFeatureReason.REASON_DEQUEUING

  • CiscoFeatureReason.REASON_DEQUEUING_TIMER_EXPIRED

  • CiscoFeatureReason.REASON_DEQUEUING_AGENTS_BUSY

  • CiscoFeatureReason.REASON_DEQUEUING_AGENTS_UNAVAILABLE

The above reasons indicate when a call gets enqueued and dequeued respectively because of the various configurations on the Hunt Pilot.


Note


The behavior is different when conferencing a queued calls. If a caller which is in a queue conferences the call with another party, then the queued connection is dropped and a new connection is created with the address of the hunt pilot number and the address type is CiscoAddress.UNKNOWN, and it will be moved to CallControlConnection.ESTABLISHED state.

If a call is removed from the queue, for example when an agent becomes free, the agent will be added to the conference and a connection will be created for it. For the Hunt Pilot, JTAPI creates a normal connection instead of a CiscoHuntConnection. This is a limitation of JTAPI in handling a conference with Hunt Pilot.

In a case where only the Hunt member is observed, there will be no issues and JTAPI will be able to handle it.

Backward Compatibility

This feature is backward compatible. Check the Queue Calls checkbox in the Hunt Pilot Configuration window to enable this feature. By default this feature is disabled.

Network Alerting

In earlier releases of CiscoJTAPI (CiscoJTAPI versions 1.4(x.y)), when a call was made to an address outside of the cluster, CallCtlConnNetworkReachedEv and CallCtlConnNetworkAlertingEv events were delivered to the farend address.

In later versions of Cisco Unified Communications Manager (4.0 and above) and Cisco Unified JTAPI (2.0), these events were not delivered. In these versions CallCtlConnection for the farend address went to the ESTABLISHED state from the OFFERED state. The previous versions of Cisco Unified JTAPI delivered CallCtlConnOfferedEv, CallCtlConnEstablishedEv for the farend address when a call was made across a gateway with "overlap sending" turned off. CallCtlConnNetworkReachedEv and CallCtlConnNetworkAlertingEv events were not delivered to the application.

In Cisco Unified Communications Manager4.0 and 4.1, the "Allow overlap sending" flag on the route pattern configured for the gateway or the "AllowNetworkEventsAfterOffered" parameter in jtapi.ini needed to be turned on to receive network events.

In Cisco Unified Communications ManagerRelease 5.0, if the "Allow overlap sending" flag is enabled, an application sees ConnCreatedEv, CallCtlConnNetworkReachedEv, CallCtlConnNetworkAlertingEv, and CallCtlConnEstablishedEv for the farend address for calls across a gateway.

If the "Allow overlap sending" flag is not enabled, an application sees ConnCreatedEv, CallCtlConnOfferedEv, CallCtlConnNetworkReachedEv, CallCtlConnNetworkAlertingEv, and CallCtlConnEstablishedEv for the farend address for calls across a gateway.


Note


AllowNetworkEventsAfterOffered is not available in Cisco Unified Communications Manager Release5.0. The above events are delivered regardless of the jtapi.ini parameter setting.


Backward Compatibility

This feature is not backward compatible.

Network Events

In previous releases of Cisco Unified JTAPI, when a call is made to an address outside the cluster, CallCtlConnNetworkReachedEv and CallCtlConnNetworkAlertingEv events are delivered for the far-end address.

In Cisco Unified Communications Manager 4.0 and later, these events do not get delivered. In these versions CallCtlConnection for the far-end address goes to the ESTABLISHED state from OFFERED state. The application will receive CallCtlConnOfferedEv, CallCtlConnEstablishedEv for the far-end address. The CallCtlConnNetworkReachedEv and CallCtlConnNetworkAlertingEv events do not get delivered to the application. To receive network events, the "Allow overlap sending" flag on the route pattern that is configured for the gateway must be turned on.

A new jtapi.ini parameter, AllowNetworkEventsAfterOffered, that is introduced allow the application to control the delivery of these events. Applications that need the network events but cannot turn on this flag can use this new jtapi.ini parameter to receive network events for outgoing calls.

To turn on the parameter, complete the following steps:

Procedure


Step 1

Run jtprefs and select the required options. This creates jtapi.ini file in c:\winnt\java\lib, if Cisco Unified JTAPI is installed in the default directory. If the jtapi.ini file already exists, you can update the file directly without running jtprefs.

Step 2

Add AllowNetworkEventsAfterOffered = 1 to the end of the file and save it.

Step 3

Repeat the preceding step every time Cisco Unified JTAPI is reinstalled.

When the AllowNetworkEventsAfterOffered flag is enabled, the application will receive CallCtlConnOfferedEv, CallCtlConnNetworkReachedEv or CallCtlConnNetworkAlertingEv and CallCtlConnEstablishedEv for the far-end address.


New Error Code in CiscoTermRegistrationFailedEv

This event is sent to application when TerminalRegistration fails for some reason. The return value of getErrorCode() interface indicates the type of failure. On receiving this event, application should try to reregister the Terminal. In this version a new return value is added to this interface. CiscoTermRegistraionFailedEv.UNKNOWN is introduced in this version to handle unknown failures.

Backward Compatibility

This feature is backward compatible.

Noncontroller Adding of Parties to Conferences

Any party in a conference can now add participants into the conference. In previous releases, only the conference controller could add participants.

  • CiscoConferenceStartEv contains an identifier for the requestor party.

  • The method getConferenceControllerAddress returns the terminal connection of the requestor.

  • The new method getOriginalConferenceControllerAddress() for CiscoConferenceStartEv returns the terminal connection of the original controller.

Park DN Monitor

Cisco Unified JTAPI applications can register to receive events when calls are parked and unparked. CiscoProvCallParkEv events will be delivered to provider observer when the application registers for this feature. To successfully register for this feature, ensure that the "call park retrieval allowed" flag for the user is turned on. You can access this flag with the user configuration on Cisco Unified Communications Manager Administration. After registering for this feature, the application will receive CiscoProvCallParkEv events whenever a call is parked or unparked from any device in the cluster.

The following new interfaces allow applications to register and unregister for this feature:

public interface CiscoProvider {
public void registerFeature ( int featureID ) throws 
     InvalidStateException,  PrivilegeViolationException;
public void unregisterFeature ( int featureID ) throws 
     InvalidStateException;
}

The featureID is CiscoProvFeatureID.MONITOR_CALLPARK_DN.

Park Monitoring and Assisted DPark Support

This feature provides a new park reversion behavior to applications invoking park request. Currently, when the park reversion timer expires, the call is reverted to the address of the parker. With the new behavior, the call remains parked at the park DN, even as the Park Monitoring reversion timer expires.

This feature also enables status monitoring of the parked call at the address of the parker. After a call is parked using the existing CiscoConnection.park() JTAPI API on newer phones or directly from the phone itself, Cisco Unified JTAPI delivers a new event CiscoAddrParkStatusEv, which includes the current status of the parked call. The application must then add AddressObserver on the address of the parker, and enable a filter to receive this event. If application adds an observer after the call is parked, then the events are delivered with CAUSE_SNAPSHOT. The park status in the new event can be one of the following:

  • Parked—Indicates a call was parked by the user of the application.

  • Reminder—Indicates the park monitoring reversion timer for the parked call has expired.

  • Retrieved—Indicates a previously parked call was retrieved.

  • Abandoned—Indicates a previously parked call is disconnected while waiting to be retrieved.

  • Forwarded: indicates the parked call has been forwarded to the configured Park Monitoring Forwarded No Retrieve destination, as the Park Monitoring Forward-No-retrieve timer has expired.

When the cause is CAUSE_SNAPSHOT the park status can be either Parked or Reminder state only.

On the phone, these notifications are targeted, that is, only the device parking the call can see these notifications (devices sharing line with the parker's device does not receive similar notifications). In Cisco Unified JTAPI, getTerminal() interface on CiscoAddrParkStatusEv has been added tomanage this. This returns the terminal on whose address, these notifications were received and this is the terminal that parked the call.

Cisco Unified JTAPI also provides the CiscoCallID to applications in this new event. Applications may use this to retrieve the call object. However CiscoCallID.getCall() may return null value if the call does not exist in the provider's domain at the time this event is received.

Cisco Unified JTAPI provides a new interface CiscoAddrEvFilter to control or filter the new event notifications to applications. Applications may get or set the filter value through the APIs getCiscoAddrParkStatusEvFilter() and setCiscoAddrParkStatusEvFilter() on the CiscoAddrEvFilter interface. Two new methods, getFilter() and setFilter(), have also been provided in the CiscoAddress to get and set the values of the filters in the CiscoAddrEvFilter interface. Applications receive the new event notification CiscoAddrParkStatusEv only if the filter is enabled and the setFilter() is invoked on CiscoAddress. By default, the filter value for CiscoAddrParkStatusEvFilter is false to maintain backward compatibility.

When a call is parked, the Park monitoring reversion timer starts and then expires. After this, Park Monitoring Forward No Retrieve timer starts. When this timer expires, and the Forward No Retrieve destination is configured, the call is forwarded to this destination. A new CiscoFeatureReason FORWARD_NO_RETRIEVE is delivered in the connection events, when connections are created at the forwarded destination. If the Forward No Retrieve destination is not configured, call is forwarded back to the parker's DN, with the same reason as when park reversion occurs (CiscoFeatureReason.PARKREMINDER).

When application invokes CiscoAddress.getAddressCallInfo(Terminal term), the CiscAddressCallInfo which is returned is now enhanced to include number of parked calls. This returns the number of parked calls. Cisco Unified IP Phone 7900 Series with SIP/SCCP returns zero value even if there are calls parked by this address.

This feature is applicable only when newer phones park the call. If Cisco Unified IP Phone 7900 Series with SIP/ SCCP, parks the call, user continues to see the existing behavior. So, if a Cisco Unified IP Phone parks the call and is sharing a line with a Cisco Unified IP Phone 7900 Series with SIP, the new Park Monitoring enhancements can be seen. However, if the Cisco Unified IP Phone 7900 Series with SIP or SCCP invoked park, the old Park behavior would be seen on all the phones, if application is monitoring any of these lines.

Users can set the Park Monitoring Reversion Timer to zero and set the Park Monitoring Forward No Retrieve Destination to the existing Park Reversion Duration timer to get the old behavior on the Cisco Unified IP Phone (provided the Forward No Retrieve destination is not configured) if the user so desires. However, the event notification cannot be controlled.

On Cisco Unified Communications Manager Service Parameter pages, the timers mentioned above can be configured. These would apply only for SIP versions of future models of Cisco Unified IP Phone .

Park Monitoring Reversion timer: This timer is started as soon as the call is parked. This is the amount of time that a call remains parked before the user is reminded that there is a parked call. The range is 0-1200 seconds, with default value of 60 seconds.

Park Monitoring Periodic reversion timer: The frequency in which the user is reminded about the parked call. The range is 0-1200 seconds, with default value of 30 seconds.

Park Monitoring Forward No Retrieve timer: This timer is started when the park monitoring reversion timer expires. This is how long, in seconds, the park reminder notification plays before the parkee is redirected to the parker's Park Monitoring Forward No Retrieve (FNR) destination. The range is 30-1200 seconds, with default value of 300 seconds.

Park Monitoring Forward No Retrieve Destination is configurable on the line page in Cisco Unified Communications Manager Line page settings.

Assisted DPark provides an alternative one step way to perform DPark operation on phones. When user performs Assisted DPark from newer phones and application is monitoring the parked party, Cisco Unified JTAPI provides reason CiscoFeatureReason.REASON_REFER in the connection events (ConnCreatedEv, ConnInProgressEv and CallCtlConnQueuedEv) for DPark DN. Currently when DPark is done, application gets connection events with CiscoFeatureReason.REASON_TRANSFER.

Backward Compatibility

Park Monitoring enhancements and Assisted DPark support are backward compatible.

The new park reversion behavior improves the user experience to allow the parked call to be retrievable for as long as possible. It also improves the usability of the park feature by allowing the user to monitor the status of a parked call through the new event being delivered.

Applications can conditionally enable/disable filter to receive event via setCiscoAddrParkStatusEvFilter() API on CiscoAddeEvFilter. By default this filter is disabled and therefore maintains backward compatibility.

If the application uses a JTAPI client older than 7.1.2, the devices are not restricted but if the application tries to observe these devices (which supports this feature to be invoked manually), JTAPI throws an exception and marks these devices as restricted from there on.

Park Reminder

When a parked call is not retrieved for a specified time, a reminder call returns to the address that parked the call, and Park Number connection moves to the Disconnected state. The call reconnects and moves to the Established state. A terminal connection in Talking state gets created for the address that parked the call.

Park Retrieval

When a call is parked from an IP phone, the park number displays on the phone. Any terminal can unpark the call by dialing the park number. When a call is unparked, a new call gets created with connections to unparked address. The CallControlConnection for the park number in the original call, which is in the Queued state, moves to the Disconnected state.

Partition Support

Prior to Cisco Unified Communications Manager Release 5.0, JTAPI did not support partitions. JTAPI considered addresses with the same DN, but different partitions, as same address. It created only one Address object for such cases because addresses are identified only by their DN and not by their partition information.

Beginning with Release 5.0, JTAPI supports addresses that have the same DN but belong to different partitions and treats them as different addresses. Partition information of the addresses is exposed to applications through the methods specified below. Applications that want to make use of this partition support feature must use the API provided to them through JTAPI interfaces and use the address objects accordingly.

This feature is backward compatible. JTAPI supports the current APIs that are used to open and access address objects.

In Cisco Unified Communications Manager Release 5.0, JTAPI is partition aware, and the following configurations are supported.

  • Addresses with the same DN, in the same partition, and in different devices get treated as shared lines.

  • The system does not allow addresses with the same DN, in the same partition and in the same device.

  • Addresses with the same DN, in different partitions, and in the same device get treated as different addresses. Two address objects get created for this scenario, and the application can distinguish between the two by calling the getPartition() API on the address objects.

  • Addresses with the same DN, in different partitions, and in different devices get treated as different addresses. Two address objects get created for this scenario and the application can distinguish between the two by calling the getPartition() API on the address objects.

Partition support changes in JTAPI are confined to the address objects and do not affect any other functions or classes of JTAPI. The following sections specify the interface changes.

CiscoAddress Interface

A new method is provided in this class with the following signature.

string getPartition ()

Returns the partition string of the address object. Applications need to use this method to get the partition information. JTAPI uses this partition information to distinguish between addresses that have the same DN but belong to different partitions and sends the partition information to open the specific addresses.

For example, a provider open returns two addresses, A(1000, P1) and B (1000, P2), where A and B denote the address objects, 1000 denotes the DN of the address objects, and P1, P2 indicate the partitions to which the addresses belong.

Figure 6. Provider Open Returns Two Addresses


When the user invokes A.getPartition (), P1 gets returned while B.getPartition () returns P2.

The provider.getAddresses() method returns multiple addresses in which the Address objects have the same DN but different partition information. An Application can use this method to distinguish between two Address objects that have the same DN but belong to different partitions.

CiscoProvider Interface

The CiscoProvider interface provides the following methods:

Address[]

getAddress(String number)

Returns an array of Address objects that corresponds to the number and different partitions.

Address

getAddress(String number, String partition)

Returns the Address object that has the same DN as the number parameter and belongs to the same partition as specified by the partition parameter.

If two addresses A(1000, P1) and B(1000, P2) exist, where A and B denote the address objects, 1000 denotes the DN of the address objects, and P1, P2 indicate the partitions to which the addresses belong, when an application calls provider.getAddress("1000"), it gets two address objects, A and B.

Figure 7. provider.GetAddress() Returns Two Address Objects


When the application calls A.getPartition(), it returns P1, B.getPartition() returns P2, and so on. An Application can distinguish between the two address objects that are using the getPartition method.

Consider the case where the application calls provider.getAddress(1000, P1). In this case, the application specifically looks for the address object whose DN is 1000 and partition is P1. In this case, "A" gets returned by the provider object.

Figure 8. Provider Calls a Specific Address and Partition


CiscoProvCallParkEv Event

CiscoProvCallParkEv provides the following methods in this interface.

string getParkingPartyPartition()

Returns the partition string of the parking party.

string getParkedPartyPartition()

Returns the partition string of the parked party.

string getParkPartyPartition()

Returns the partition string of the park DN.

For details on the interface changes, see Cisco Unified JTAPI Extensions To view the message sequences for partitions support, see Message Sequence Charts

Password Expiry

The administrator can use the CUCM Admin Panel to configure options for login credentials. The password expiry configuration allows the administrator to specify the following two parameters:

  1. The time before the password expires (in days) and

  2. The number of days before the end of the password expiry to alert the user to change the password.

If a password is expired, JTAPI delivers an exception to the application. In a situation where a password is going to expire soon, JTAPI delivers a new event to the application. JTAPI does not allow applications to modify any of these values, it only reports the information.

Backward Compatibility

This feature is backward compatible.

Persistent Connection

Persistent Connection is an extension Cisco Extend and Connect feature that was implemented in Unified Communications Manager Release 9.1. A persistent call refers to a call between the Unified Communications manager (CTI Remote Device) and a remote destination that stays up even after calls to it are dropped. JTAPI APIs and error codes were added.

JTAPI supports a new API, CiscoAddress.createPersistentCall(), which allows applications to create persistent calls. At least one remote destination must be configured and the active remote destination must be set. There can be only one persistent call per remote device. Persistent calls cannot be created if there is already a call on the remote device; otherwise, the application receives CiscoJtapiException.OPERATION_NOT_AVAILABLE_IN_CURRENT_STATE. Furthermore, no feature invocations are allowed on or involving persistent calls (park, hold, conference, and transfer).

Two new JTAPI APIs return information about the persistent call. The CiscoAddress.getPersistentConnection() API returns the connection object that is associated to the persistent call. It returns null if no persistent call exists. This API also allows you to check if an address has a persistent connection created on it and from there you can get the call object. The other newly added API is CiscoCallisPersistentCall(), which returns true if the call is a persistent call and false if the call is a normal call.

Existing JTAPI APIs such as Provider.getCalls(), Address.getConnections(), and Terminal.getTerminalConnections() return only the information for normal calls and do not return anything for the persistent call. Provider.getCalls() returns all the calls that are associated with the provider, excluding the persistent calls. Address.getConnections() returns all the connection objects that are associated with this address, excluding the connection for the persistent call. Terminal.getTerminalConnections() returns all the terminal connection objects that are associated with this device, excluding the terminal connection for the persistent call. This functionality helps with backward compatibility so applications do not need to make any changes to their current implementations.

No new APIs are added to disconnect the persistent calls. Existing Call.drop() and Connection.disconnect() JTAPI APIs can be used to disconnect or drop the persistent calls. Persistent calls cannot be dropped if there is an active call to the remote device. Persistent calls can also be dropped in any of the following scenarios:

  • The call is dropped by the remote destination (the remote destination hangs up).

  • The remote destination is no longer active. If there is an active call, as soon as that call is over, the persistent call will drop.

After they are created, persistent calls remain connected until the maximum call duration timer expires in which case the call will be cleared.

Some of the new JTAPI Error Codes introduced as part of this feature include the following:

  • CiscoJtapiException.CTIERR_CREATE_PERSISTENT_CALL_FAILED: Indicates that there is an issue with creating a persistent call.
  • CiscoJtapiException.CTIERR_PERSISTENT_CALL_EXISTS: Indicates that a persistent call already exists.
  • CiscoJtapiException.CTIERR_OPERATION_NOT_ALLOWED_ON_PERSISTENT_CALL: Indicates that the specified operation is not allowed on a persistent call.
  • CiscoJtapiException.CTIERR_DISCONNECT_PERSISTENT_CALL_FAILED_CALL_ACTIVE: Indicates that the request to disconnect the persistent call failed because there is an active customer call. Only when there are no active calls can the persistent call be disconnected.
  • CiscoJtapiException.CTIERR_PERSISTENT_CALL_BEING_SETUP: Indicates that the request failed because a persistent call is already being set up.

Backward Compatibility

This feature is backward compatible and existing applications are not affected by this feature.

Interface CiscoAddress Changes

CiscoAddress is enhanced with the addition of new APIs to create a persistent call and to retrieve the connection object that is associated to the persistent call.

CiscoCall

createPersistentCall (Terminal terminal, String callerIDNumber, String callerIDName)

This interface creates a persistent call for this address and will return the call object for the newly created call. Note that CiscoProvider and the address must be in IN_SERVICE state, otherwise InvalidStateException will be thrown. This API cannot be invoked on external addresses. Doing so will result in MethodNotSupportedException to be thrown. If while trying to allocate a globalCallId for the persistent call and an error occurs, ResourceUnavailableException will be thrown. All other errors encountered will result in PlatformException to be thrown.

Connection

getPersistentConnection (Terminal terminal)

This interface will return the connection object that is associated with the persistent call. It returns null if there is no persistent call. This API cannot be invoked on external addresses. Doing so will result in MethodNotSupportedException to be thrown.

Interface CiscoCall Changes

CiscoCall represents a call in the JTAPI model. This interface is enhanced with the addition of a new API.

boolean

isPersistentCall ()

This interface returns true if the call is a persistent call and false otherwise (if it is a normal call).

Interface CiscoJtapiException Changes

CiscoJtapiException contains all of the error codes that can be delivered by JTAPI to applications. This interface is enhanced with the addition of new error codes.

public static final int

  • CTIERR_CREATE_PERSISTENT_CALL_FAILED = "Failed to create Persistent Call." (0x8CCC0132)
  • CTIERR_PERSISTENT_CALL_EXISTS = "Persistent Call exists." (0x8CCC0133)
  • CTIERR_OPERATION_NOT_ALLOWED_ON_PERSISTENT_CALL = "Operation is not allowed on a Persistent Call." (0x8CCC0134)
  • CTIERR_DISCONNECT_PERSISTENT_CALL_FAILED_CALL_ACTIVE = "Disconnect persistent call failing, there are active calls." (0x8CCC0136)
  • CTIERR_PERSISTENT_CALL_BEING_SETUP = "Persistent Call is being set up." (0x8CCC0139)

Play Zip Tone

The Play Zip Tone feature allows Cisco JTAPI application to play zip tones on active calls. The application specifies the type and the direction of the tone.

Zip tones are played at local or remote end of the call. They are audible and played only for IP phones. These tones are not played if the remote side is a trunk, conference or Cisco Media Terminal or Route Terminal.

The following tones can be played:

  • CiscoTone.ZIPZIP

  • CiscoTone.ZIP

  • CiscoTone.CALLWAITINGTONE

Sample Code

Void playTone(TerminalConnection termConn,  int tone,  int direction){
      If ( termConn  ! =  null ){
try {
((CiscoTerminalConnection)termConn).playTone(tone,  direction);
} catch (Exception e){
System.out.println("Exception for playtone request " + e);
}

Backward Compatibility

Presentation Indicator for Calls

The presentation indicator (PI) on a call provides the application with the ability to hide or reveal Calling/Called/CurrentCalling/CurrentCalled/LastRedirecting parties name and number to the end user. JTAPI provides functions on CiscoCall to get PI value for the party. Use this PI info to present the parties information to the end user. These functions return a value of true or false. A value of "True" indicates that presentation in "Allowed, " and a value of "False" indicates the presentation is "Restricted."

For a conference call, the interfaces on CiscoCall do not return a correct value. Applications must iterate through all the connections in the call to get the PI value that is associated with the address for which the connection gets created. The interface that is provided on CiscoConnection is getAddressPI().

The following new interfaces exist on CiscoCall retrieve PI values.

CiscoCall

boolean

getCalledAddressPI()

Returns the PI that is associated with getCalledAddressPI. If it returns true, the application displays the address name. If it returns false, the application must not display the address name.

boolean

getCallingAddressPI()

Returns the PI that is associated with getCallingAddressPI. If it returns true, the application displays the address name. If it returns false, the application must not display the address name.

boolean

getCurrentCalledAddressPI()

Returns the PI that is associated with CurrentCalledAddressPI. If it returns true, the application displays the address name. If it returns false, the application must not display the address name.

boolean

getCurrentCalledDisplayNamePI()

Returns the PI that is associated with CurrentCalledDisplayNamePI. If it returns true, the application displays the address name. If it returns false, the application must not display the address name.

boolean

getCurrentCallingAddressPI()

Returns the PI that is associated with getCurrentCallingAddressPI. If it returns true, the application displays the address name. If it returns false, the application must not display the address name.

boolean

getCurrentCallingDisplayNamePI()

Returns the PI that is associated with getCurrentCallingDisplayNamePI. If it returns true, the application displays the address name. If it returns false, the application must not display the address name.

boolean

getLastRedirectingAddressPI()

Returns the PI that is associated with getLastRedirectingAddressPI. If it returns true, the application displays the address name. If it returns false, the application must not display the address name.

The following interface on CiscoConnection retrieves the PI value for the address that is associated with the connection:

CiscoConnection

boolean

getAddressPI()

Returns the PI that is associated with the address on which the connection gets created. If it returns true, the application displays the address name. If it returns false, the application must not display the address name.

No change exist in the message flow.

Privacy On Hold

This feature enhances the privacy of private held calls. When privacy is enabled, only the phone that placed a call on hold can retrieve that call, and the calling name and number are not displayed.

The feature provides the ability for a shared address to determine whether other shared addresses may barge into a call. When privacy is enabled, other shared address cannot barge into the call. Privacy is a terminals property. On IP phones, a Privacy feature button allows the users to enable and disable the privacy feature. Privacy can be dynamically enabled and disabled for the active calls on the terminal. When Privacy is on for a call, the TerminalConnection state available to other shared addresses is set to In Use. If Privacy status is changed during the CallProgress, CiscoTermConnPrivacyChangedEvent is delivered to the application.

In prior releases, if Privacy is enabled and the call is put on hold, all TerminalConnections were in TermConnHeld state and any other shared Address terminalConnection could unhold the call. In Cisco Unified Communications Manager 4.2, if the Enforce Privacy on Held Calls service parameter is enabled, and if Privacy is enabled for a call, putting the call on hold does not change the terminalConnections of other shared addresses and they remain in the In Use state.

Performance and Scalability

There is no performance impact with this feature because there is no additional traffic generated between Cisco Unified JTAPI, applications, and Cisco Unified Communications Manager.

Progress State Converted to Disconnect State

If an outbound call is initiated through the API to an unallocated directory number across the European PSTN, the application will perceive the ConnFailedEv event with the cause as CiscoCallEv.CAUSE_UNALLOCATEDNUMBER. For the US PSTN, the application may not see any event.

To make the behavior consistent across the European and American PSTNs and also to address backward compatibility issues, a new service parameter UseProgressAsDisconnectedDuringErrorEnabled was added to the jtapi.ini file starting with JTAPI Version 1.4(3.21), which, when enabled (1 = enable; 0 = disable; the default is disable), causes applications to perceive ConnFailedEv in both cases.

Q.Signaling (QSIG) Path Replacement

QSIG Path Replacement, a network feature, optimizes the real-time protocol (RTP) path when calls are transferred or forwarded to other PBXs that are connected through QSIG trunks. When path replacement is in progress, a small window of time exists when the feature requests from applications would be ignored and JTAPI would throw an exception to the application.

The Global Call ID or the call is changed when the RTP path is optimized with a direct path between the starting terminating PBXs. JTAPI provides new interfaces to monitor the call.

QoS Support

QoS support is enhanced in this release to enable QoS (DSCP marking) in both directions of the application <--> CTIManager connectivity. In previous releases it was enabled in only one direction: CTIManager --> application.

The DSCP (QoS) values for both directions of the link are set by the "DSCP IP CTIManager to Application" value in the CTIManager service parameters. The default value is CS3(precedence 3) DSCP (011000).

The "DSCP value for Audio calls" service parameter is the recommended QoS value for audio calls. Thisvalue is exposed to JTAPI applications.

You must perform one of the following setup procedures on the client machine for JTAPI QoS to work on Windows platforms.

Procedure


Step 1

If you are running Windows 2000, follow the steps in QoS Setup on Windows 2000.

Step 2

If you are running Windows XP or Windows Server 2003, follow the steps in QoS Setup on Windows XP Server 2003.


What to do next

For more information on using the Registry Editor to set the Internet Protocol Type of Service bits, see the topic "Setsockopt is unable to mark the Internet Protocol type of service bits in Internet Protocol packet header" on the Microsoft technical support website.

These JTAPI interfaces support QoS:

Provider Interface

int

getAppDSCPValue()

Returns the "DSCP IP for CTI applications" service parameter. This value specifies the DSCP value that JTAPI sets on its link to CTI. Applications can get this value by querying the provider object by using this API every time that they get a ProviderInServiceEvent.

private int

precedenceValue = 0x00

Stores the DSCP value that CTI provides.

For details on these interfaces, see Cisco Unified JTAPI Extensions To view the message flow for QoS, see Message Sequence Charts.

QoS Setup on Windows 2000

If you are running Windows 2000, follow these steps.

Procedure


Step 1

Start the Registry Editor (Regedt32.exe).

Step 2

Go to key: HKEY_LOCAL_MACHINE on Local Machine\System\CurrentControlSet\Services\Tcpip\Parameters\

Step 3

On the Edit menu, click Add Value.

Step 4

In the Value name box, enter DisableUserTOSSetting.

Step 5

In the Data Type list, click REG_DWORD and then click OK.

Step 6

In the Data box, enter a value of 0 (zero) and then click OK.

Step 7

Quit Registry Editor and then restart the computer.


QoS Setup on Windows XP Server 2003

If you are running Windows XP or Windows Server 2003, follow these steps.

Procedure


Step 1

Start Registry Editor (Regedt32.exe).

Step 2

Go to key: HKEY_LOCAL_MACHINE on Local Machine\System\CurrentControlSet\Services\Tcpip\Parameters\

Step 3

On the Edit menu, point to New, and then click DWORD Value.

Step 4

Enter DisableUserTOSSetting as the entry name, and then press ENTER.

When you add this entry, the value gets set to 0 (zero). Do not change the value.

Step 5

Quit Registry Editor and then restart the computer.


Quiet Clear

QuietClear occurs at the other end when two parties are on a call, and one address goes out of service because of a network outage, the Cisco Unified Communications Manager goes down, the application controlling CTIPort goes down, or CTIManager goes down. At this stage, the other end of the call can only drop the call or disconnect the connection. It cannot perform any other callControl operations.

For the party that went out of service, applications will perceive ConnDisconnectedEv and/or TermConnDroppedEv, and the other end of the call receives ConnFailedEv with CiscoCause of CiscoCallEv.CAUSE_TEMPORARYFAILURE.

If applications try to invoke the following features during QuietClear mode, PlatformException with error code of CiscoJtapiException.CTIERR_OPERATION_FAILER_QUIETCLEAR gets thrown:

  • Consult transfer

  • Consult conference

  • Blind transfer

  • Hold

  • Unhold


Note


Applications may only drop the call in this mode.


Receiving and Responding to Media Flow Events

Whenever a media stream must be created between two endpoints, Cisco Unified Communications Manager issues start transmission and start reception events to both endpoints. In JTAPI, the CiscoRTPOutputStartedEv and CiscoRTPInputStartedEv events represent the start transmission and start reception events. The CiscoRTPOutputStartedEv.getRTPOutputProperties() method returns a CiscoRTPOutputProperties object, from which the application can determine the destination address of its peer endpoint in the call, as well as the other RTP properties for the stream such as payload type and packet size. Similarly, the CiscoRTPInputStartedEv.getRTPInputProperties() method returns a CiscoRTPInputProperties object that informs the application of the RTP characteristics for the inbound stream.

At any time while media is flowing, the current CiscoRTPOutputProperties and CiscoRTPInputProperties also remain available from the CiscoMediaTerminal.getRTPOutputProperties() and CiscoMediaTerminal.getRTPInputProperties() methods as well. These methods throw an exception if the CiscoMediaTerminal is not currently supposed to transmit or receive media.

When Cisco Unified Communications Manager wants the application to stop sending or receiving media as the result of a call disconnecting or being put on hold, for example, it sends the CiscoRTPOutputStoppedEv and CiscoRTPInputStoppedEv events. These events mean that the current RTP media stream that exists between the two endpoints should be torn down.

Inbound Call Media Flow Event Diagram

The following table illustrates the dialogue between Cisco Unified Communications Manager and a JTAPI application when a call is presented to an application-controlled endpoint. The events in the left column represent JTAPI events that are sent to the CallObserver of the application, and the requests in the right column represent methods that the application invokes.
