Current Call

The Client Interface Library uses the concept of a Current Call. The CTI OS Toolkit uses the Current Call concept as a way for the controls and the application to communicate with each other regarding which call is currently selected and is the one to act on. For example, if an agent has a call and receives a new Ringing call, they might select the Talking call on the grid. At this click, CallAppearanceMgr control calls SetCurrentCall() to make this call the Current Call. When the agent clicks the Hold control, this control calls GetCurrentCall() to obtain a call pointer through which to call the Hold() method. The agent can then select the Ringing call, which again causes the CallAppearanceMgr control to call SetCurrentCall() to make this new call the current call. Then, when the agent clicks the Answer control, this control again calls GetCurrentCall() to obtain a call pointer through which to call the Answer() method.

If your application uses Cisco's out-of-the-box button controls (for more information, see CTI OS ActiveX Controls), but not the CallAppearanceMgr grid control, you need to use SetCurrentCall() and GetCurrentCall() for the button controls to enable and disable correctly when switching between multiple calls.

Note	The CurrentCall concept does not place any limitations on call control of non-current calls. All of the call behaviors implemented by method calls on the Call object work on any Call object that is available at the CIL, even if it is not the CurrentCall.

  Answer([reserved_args As IArguments]) As Long

  as follows:

  Answer()

• To ignore these parameters in COM you must send a NULL, as shown:

  Answer (NULL)

Alternate

The Alternate method combines the action of placing a talking call on hold and then retrieving a previously held call at the same device. If there are only two calls at the device, this method can be called via either the current or the held call.

Syntax

C++

int Alternate()
int Alternate(Arguments & reserved_args);

COM

HRESULT Alternate (/*[in,optional]*/ IArguments *reserved_args, (/*[out, retval]*/ int * errorcode );

VB

Alternate([reserved_args As IArguments]) As Long

Java

int Alternate(Arguments rArgs);

.NET

CilError Alternate(Arguments args)

Parameters

reserved_args

A valid Arguments object, which can be empty. Not currently used, reserved for future use.

errorcode

An output parameter (return parameter in VB) that contains an error code from Table 1.

Return Values

Default CTI OS return values. For more information, see CIL Coding Conventions.

Remarks

For switches that allow more than two calls at a device (for example G3), make this request only through the desired held call, because of the ambiguity caused by multiple held calls at the device.

You must make the Alternate request via a call whose status is either LCS_CONNECT or LCS_HELD or it fails.

The following events are received if this request is successful.

For the call making the Alternate request:

• OnAlternateCallConf event

For the originally current call:

• OnCallHeld event

For the originally held call:

• OnCallRetrieved event

The following events are received by the call making the Alternate request if this request fails:

• OnControlFailureConf event

Answer

The Answer method answers a call that is in the alerting or ringing state (i.e., call status of LCS_ALERTING).

Syntax

C++

int Answer()
int Answer(Arguments & reserved_args)

COM

HRESULT Answer (/*[in,optional]*/ IArguments *reserved_args, (/*[out, retval]*/ int * errorcode )

VB

Answer([reserved_args As IArguments]) As Long

Java

int Answer(Arguments rArgs)

.NET

CilError Answer(Arguments args)

Parameters

reserved_args

Not currently used, reserved for future use.

errorcode

An output parameter (return parameter in VB) that contains an error code from Table 1.

Return Value

Default CTI OS return values. For more information, see CIL Coding Conventions.

Remarks

You can answer a call after the OnCallDelivered event is received. You must make the Answer request via a call whose call status LCS_ALERTING or it fails.

The following events are received if this request is successful:

• OnAnswerCallConf event
• OnCallEstablished event

The following events are received if this request fails:

• OnControlFailureConf event

Clear

The Clear method clears the call and drops all parties to the call.

Syntax

C++

int Clear()int Clear(Arguments & reserved_args);

COM

HRESULT Clear (/*[in,optional]*/ IArguments *reserved_args, (/*[out, retval]*/ int * errorcode )

VB

Clear([reserved_args As IArguments]) As Long

Java

int Clear(Arguments rArgs);

.NET

CilError Clear(Arguments args);

Parameters

reserved_args

Not currently used, reserved for future use.

errorcode

An output parameter (return parameter in VB) that contains an error code from Table 1.

Return Value

Default CTI OS return values. For more information, see CIL Coding Conventions.

Remarks

In the case of a multi-party Conference call, calling Clear() results in all of the parties to the call being hung up. (If this is not the desired behavior, see the ClearConnection method.) Under certain switches the Clear request is made via a call whose status is LCS_CONNECT or LCS_INITIATE or it fails. Many other switches allow the Clear method to be called via a call whose status is LCS_ALERTING or LCS_HOLD. It can never be made via a call whose status is LCS_NULL indicating that it is already cleared.

The following events are received if this request is successful:

• OnClearCallConf event
• OnCallCleared event

The following events are received if this request fails:

• OnControlFailureConf event

Note	The Clear method is not supported on Unified CCE. Use of the Clear method with Unified CCE results in loss of third-party call control. To avoid this error, applications should use the ClearConnection method instead of Clear to hang up a call.

ClearConnection

If there are only two parties to the call, ClearConnection clears the call. However, for a multi-party conference call, only one connection is dropped, which is its own connection.

Syntax

C++

int ClearConnection()
int ClearConnection(Arguments & reserved_args);

COM

HRESULT ClearConnection (/*[in,optional]*/ IArguments *reserved_args, (/*[out, retval]*/ int * errorcode)

VB

ClearConnection([reserved_args As IArguments]) As Long

Java

int ClearConnection(Arguments rArgs);

.NET

CilError ClearConnection(Arguments args);

Parameters

reserved_args

Not currently used, reserved for future use.

errorcode

An output parameter (return parameter in VB) that contains an error code from Table 1.

Return Value

Default CTI OS return values. For more information, see CIL Coding Conventions.

Remarks

As with the Clear method, under certain switches you must make the ClearConnection request via a call whose status is LCS_CONNECT or LCS_INITIATE or it fails. Many other switches allow the Clear method to be called via a call whose status is LCS_ALERTING or LCS_HOLD. It can never be made via a call whose status is LCS_NULL indicating that it is already cleared.

The following events are received if this request is successful:

• OnClearConnectionConf event
• OnCallConnectionlCleared event

If this is a two party call, these events are followed by:

• OnCallCleared event

The following events are received if this request fails:

• OnControlFailureConf event

Conference

The Conference method either begins a new conference call or adds an additional call to an existing conference call. When it begins a new conference call, it combines an original two-party call with a two-party consult call (where the two calls have a common party) into a single three party call. Only the common party (which is called the "Conference Controller") can call this method to make the new conference call. You can call this method on either of the Conference Controller's calls.

Syntax

C++

int Conference();
int Conference(Arguments& optional_args)

COM

HRESULT Conference ( /*[in, optional]*/ IArguments *optional_args, (/*[out, retval]*/ int * errorcode )

VB

Conference([optional_args As IArguments]) As Long

Java

int Conference(Arguments optional_args)

.NET

CilError Conference(Arguments optional_args)

Parameters

optional_args

An optional input parameter, which is a pointer or reference to an Arguments array that contains a member with the string value that is the UniqueObjectID of the call to which this call is conferenced. If this argument is used, add it to the Arguments parameter with the keyword of "CallReferenceObjectID". This is only necessary in an environment where there are multiple held calls and the request is made through the talking call. If the request is made through a specific held call in this scenario, or if there are only two calls at the device, this parameter is unnecessary.

errorcode

An output parameter (return parameter in VB) that contains an error code from Table 1.

Return Value

Default CTI OS return values. For more information, see CIL Coding Conventions.

Remarks

Before making this request, the original call must be in the held state and the consult call in the talking state or the request fails. Therefore, if the calls are alternated (see Alternate), they must be alternated again to return the two calls to their appropriate states.

If there are only two calls at the device, you can call this method using either the current or held call. For switches which allow more than two calls at a device (for example G3), make this request through the desired held call to avoid the ambiguity caused by multiple held calls at the device. Otherwise, indicate the desired held call using the optional parameter.

You must make the Conference request via a call whose call status is LCS_CONNECT or LCS_HELD or it fails.

On certain switches (notably Unified CCE), only the Conference Controller (the party that first initiated the conference call) can add additional parties to an existing conference call.

The following events are received if this request is successful:

• OnConferenceCallConf event
• OnCallConferenced event

The following events are received if this request fails:

• OnControlFailureConf event

GetCallContext

The GetCallContext method returns an Arguments array containing the values for call properties other than CallVariables and ECC Variables, such as ANI, DNIS, and the other properties listed in the following table.

Syntax

C++

int GetCallContext(Arguments& args)

Remarks

This is a convenience method to call and get all of a call's non-CallVariable data at one time. If only certain data members are desired, call the appropriate GetValue method for each instead.

GetCallData

The GetCallData method returns the values ofCallVariable1 through CallVariable10 and all of the ECC (Extended CallContext) variables.

Syntax

C++

int GetCallData(Arguments& args)

COM

HRESULT GetCallData (/*[out,retval]*/ IArguments ** args)

Java

Arguments GetCallData()

.NET

Arguments GetCallData()

Parameters

args

C++, COM, and VB: An output parameter containing a reference or a pointer to an Arguments array containing the call data, as described under Remarks.

Return Value

C++, COM, and VB: Default HRESULT return values. For more information, see CIL Coding Conventions.

Java/.NET: A reference to an Arguments array that, on return, holds parameters described under Remarks.

Remarks

This is a convenience method to call and get all of a call's CallVariables (1 through 10) and ECC Call Variables at one time. If only certain call variables are desired, call the appropriate GetValue method for each instead.

Access the data in the following way:

• To access the values for individual CallVariables from the arguments parameter, use GetValueString with either the keywords of "CallVariable1" through "CallVariable10".

To access ECC call data, use the following procedure:

• First, get the ECC variables as a whole from the arguments parameter, using GetValueArray with the keyword "ECC". This returns another Arguments array that is nested in the Arguments array returned from GetCallData.
• To access an individual ECC scalar variable from this Arguments array, use the appropriate GetValueString, GetValueInt, etc. depending on the variable's type, using the string keyword "user.VariableName".
• To access an individual ECC array variable from this Arguments array, use the appropriate GetValueString, GetValueInt, etc. depending on the variable's type, using the string keyword "user.ArrayName[n]", where n is a zero based integer that notes the offset in the array.

Hold

The Hold method holds a current call.

• OnCallHeld event

The following events are received if this request fails:

• OnControlFailureConf event

MakeConsultCall

The MakeConsultCall method initiates the combined action of placing the associated current call on hold and then making a new call. By default, the call context data (including call variables) of the current call is used to initialize the context data of the new consultation call. The application can override some or all of the original call context in the consultation call by providing the desired values in this request.

The simplest form of the request only requires a dialed number and a consult type. The request can also include optional parameters, as listed in the following table.

Syntax

C++

int MakeConsultCall (Arguments& args))

SetCallData

The SetCallData method sets any or all of a call's CallVariables (1 through 10) and ECC data at one time.

Note

When writing a custom application, in any language, call variables are not blanked out if it they are set to a NULL value. While the application attempts to clear any call variable using a NULL value, the CTI OS server application ignores the NULL value call variables and does not pass them to the CTI Server application. As a result, the call variables set to NULL are not reset. To clear the value of a call variable, set its value to a blank character. Setting the call variable to a single space character places a space in the call variable's values for the duration of the call. This space is considered a NULL value by the application.

Syntax

C++

int SetCallData(Arguments& args)

COM

HRESULT SetCallData (/*[in]*/ args *arguments, /*[out]*/ int * errorcode)

The following events are sent if this request succeeds:

• OnSetCallDataConf
• OnCallDataUpdate

The OnControlFailureConf event is sent if this request fails.

SingleStepConference

The SingleStepConference method initiates a one-step conference without the intermediate consultative call so that when the called party answers, they are joined in the current call. This method requires a DialedNumber argument. This method is not supported under all switches.

It fails if there is no recording server available to CTIServer.

• The OnStopRecordConf event is received if this request is successful.
• The OnControlFailureConf event is received if this request fails.

Transfer

The Transfer method transfers a call to a third party. You can call this method on either the held original call or the current consult call. If the device has only these two calls, the optional parameter is not necessary. At the end of a successful transfer, both of these calls are gone from the device. For more information, see the Conference method.

Syntax

C++

int Transfer();
int Transfer(Arguments& optional_args)

COM

HRESULT Transfer ( [in, optional] IArguments *optional_args, (/*[out, retval]*/ int * errorcode )

VB

Transfer([optional_args As IArguments]) As Long

Java

int Transfer(Arguments rArgs)

.NET

CilError Transfer(Arguments args)

Parameters

optional_args

An optional input parameter containing a member with a string value that is the UniqueObjectID of the call that is participating in the transfer. If this argument is used, add it to the Arguments parameter with the keyword of "CallReferenceObjectID". This is only necessary in an environment where there are multiple held calls and the request is made through the current call. If the request is made through a specific held call in this scenario, or if there are only two calls at the device, this parameter is unnecessary.

errorcode

An output parameter (return parameter in VB) that contains an error code from Table 1.

Return Values

Default CTI OS return values. For more information, see CIL Coding Conventions.

Remarks

Before making this request, the original call must be in the held state and the consult call in the talking state or the request fails. Therefore, if the calls are alternated (for more information, see Alternate), they must be alternated again to return the two calls into their appropriate states.

If there are only two calls at the device, call this method using either the current or held call. For switches that allow more than two calls at a device (for example G3), make this request only through the desired held call to avoid the ambiguity caused by multiple held calls at the device. Otherwise, indicate the desired held call by using the optional parameter.

You must make the Transfer request via a call whose call status is LCS_CONNECT or LCS_HELD or it fails.

The following events are received by the transfer initiator if this request is successful:

• OnCallTransferred event
• OnCallEnd event
• OnCallEnd event
• OnAgentStateChange event
• OnTransferCallConf event

The OnControlFailureConf event is received if this request fails.

Call Object

---

The Call object provides developers using the CTI OS Client Interface Library with an interface to Call behavior and control. The Call object enables you to perform all call behaviors, such as answering, hanging up, or transferring a call. The Call object represents one call connection of a call. For a call between two parties there are two call connections, and thus there are two distinct CIL Call objects.

The object stores specific call information as properties, including the ICMEnterpriseUniqueID, ANI, DNIS, Call variables, and ExpandedCallContext variables. The Call object is created in response to call events received at the CIL. The Call object properties and state are updated throughout the lifetime of the call connection.

For more information about accessing Call and ECC variables via the GetValue mechanism, see CIL Coding Conventions.

• Current Call
• ECC Variables
• Passing Call Variables
• ECC Variable Value Retrieval
• ECC Values
• Properties
• Methods

Current Call

The Client Interface Library uses the concept of a Current Call. The CTI OS Toolkit uses the Current Call concept as a way for the controls and the application to communicate with each other regarding which call is currently selected and is the one to act on. For example, if an agent has a call and receives a new Ringing call, they might select the Talking call on the grid. At this click, CallAppearanceMgr control calls SetCurrentCall() to make this call the Current Call. When the agent clicks the Hold control, this control calls GetCurrentCall() to obtain a call pointer through which to call the Hold() method. The agent can then select the Ringing call, which again causes the CallAppearanceMgr control to call SetCurrentCall() to make this new call the current call. Then, when the agent clicks the Answer control, this control again calls GetCurrentCall() to obtain a call pointer through which to call the Answer() method.

If your application uses Cisco's out-of-the-box button controls (for more information, see CTI OS ActiveX Controls), but not the CallAppearanceMgr grid control, you need to use SetCurrentCall() and GetCurrentCall() for the button controls to enable and disable correctly when switching between multiple calls.

Note	The CurrentCall concept does not place any limitations on call control of non-current calls. All of the call behaviors implemented by method calls on the Call object work on any Call object that is available at the CIL, even if it is not the CurrentCall.

ECC Variables

The Unified ICM provides a customer-defined data layout for sending call context data with a call. This mechanism is called Expanded Call Context, or ECC. ECC variables are defined in the Unified ICM Configuration Manager and are sent between Unified ICM servers as a key-value structure. The mechanism for accessing ECC variables from CTI OS is similar to accessing all other call variables.

To simplify the organization of properties on the Call object, the ECC variables are stored in their own Arguments structure which is nested in the Call object Arguments structure.

Passing Call Variables

• A consultative transfer is one in which the transferring or forwarding party either connects the caller to a ringing phone or speaks with the third party before connecting the caller to the third party. In a consultative transfer on the same peripheral gateway, if a variable is updated with data during the primary call, and the same variable is then updated with data during the transferred call, the call data from the initial call takes precedence and replaces the call data from the transferred call.
• For calls that are transferred between peripheral gateways, update call variables on the primary call before transferring the call. Only call variable information from the primary call is included in the route request to the other peripheral gateway. Any call variable information that you change after the call is transferred is lost because the call variable information was not included in the route request when the call was transferred.
• The Unified ICM call control variable map is a string that describes the mappings of a peripheral's call control variables to Unified ICM call control variables. You can edit this string to identify the call variables that an agent can change.

ECC Variable Value Retrieval

To retrieve an ECC variable from the Call object, first retrieve the ECC (Arguments) structure from the Call object using GetValueArray with keyword ECC. Then, retrieve the specific ECC variable required by using its name as the keyword to GetValueInt, GetValueArray, or GetValueString, depending on its type. The following is some sample code for C++ without COM:

Arguments * pECCData = NULL;string sMyECCVariable;
int nMyECCArrayVariable;

if (pCall->IsValid(CTIOS_ECC))
{
pCall->GetValueArray(CTIOS_ECC, &pECCData);

if (pECCData)
{
if (pECCData->IsValid("user.MyECC"))
pECCData->GetValueString->("user.MyECC", &sMyECCVariable);

if(pECCData->IsValid("user.MyArray[2]"))
pECCData->GetValueInt("user.MyArray[2]", &nMyECCArrayVariable);

pECCData->Release();
pECCData = NULL;
}
}

Sample code for VB without COM:

Dim MyECCData As CTIOSARGUMENTSLib.Arguments    Dim MyECCVariable As String
Dim MyECCArrayVariable As Integer

If MyCall.IsValid(CTIOS_ECC) = True Then
Set MyECCData = MyCall.GetValueArray(CTIOS_ECC)
    
If MyECCData.IsValid("user.MyECC") Then
MyECCVariable = MyECCData.GetValueString("user.MyECC")
End If
    
If MyECCData.IsValid("user.MyArray[2]") Then
MyECCArrayVariable = MyECCData.GetValueInt("user.MyArray[2]")
End If
End If

The same thing in Java is as follows:

if(Call != null){
Arguments rArgEcc = new Arguments();
rArgEcc =  Call.GetValueArray(CTIOS_ECC);
if(null != rArgEcc)
{
rArgEcc.NumElements();
Integer intVal = 
rArgEcc.GetValueIntObj("user.MyECC");
String strVal =
rArgEcc.GetValueString("userMyArray[2]");
}
}

ECC Values

If you want to add ECC values to a call without deleting ones that are already set in the call, retrieve the ECC variables and then add the new ones as shown in C++ without COM:

Arguments & RequestArgs = Arguments::CreateInstance();
Arguments * pECCData = NULL;

// presumes that we have a Call object pointer in pCall
if (pCall->IsValid (CTIOS_ECC))
pCall->GetValueArray(CTIOS_ECC, &pECCData);

else
Arguments::CreateInstance(&pECCData);


pECCData->AddItem("user.MyECC", "FirstECCVariable");
pECCData->AddItem("user.MyArray[2]", 2222);

RequestArgs.AddItem(CTIOS_ECC, *pECCData);
pCall->SetCallData(RequestArgs);

RequestArgs.Release();
pECCData->Release();

The same thing in VB is as follows:

Dim MyRequestArgs As New CTIOSARGUMENTSLib.Arguments
Dim MyECCData As CTIOSARGUMENTSLib.Arguments

If MyCall.IsValid(CTIOS_ECC) Then
Set MyECCData = MyCall.GetValueArray(CTIOS_ECC)

Else
Set MyECCData = New CTIOSARGUMENTSLib.Arguments
End If

MyECCData.AddItem("user.MyECC", "FirstECCVariable")
MyECCData.AddItem("user.MyArray[2]", 2222)

MyRequestArgs.AddItem("ECC", MyECCData)

MyCall.SetCallData(MyRequestArgs)

The same thing in Java is as follows:

Arguments rRequestArgs = new Arguments();
if(Call != null)
{
   Arguments rArgEcc = Call.GetValueArray(CTIOS_ECC);
   if(null == rArgEcc)
   {
      rArgEcc = new Arguments();
   }
   rArgEcc.SetValue("user.MyEcc", 22222);
   rArgEcc.SetValue("user.MyArray[3]", "new data");

   rRequestArgs.SetValue(CTIOS_ECC, rArgEcc);

   Call.SetCallData(rRequestArgs);
}

Default CTI OS return values. For more information, see CIL Coding Conventions.

Remarks

You can answer a call after the OnCallDelivered event is received. You must make the Answer request via a call whose call status LCS_ALERTING or it fails.

The following events are received if this request is successful:

• OnAnswerCallConf event
• OnCallEstablished event

The following events are received if this request fails:

• OnControlFailureConf event

Clear

The Clear method clears the call and drops all parties to the call.

Syntax

C++

int Clear()int Clear(Arguments & reserved_args);

COM

HRESULT Clear (/*[in,optional]*/ IArguments *reserved_args, (/*[out, retval]*/ int * errorcode )

VB

Clear([reserved_args As IArguments]) As Long

Java

int Clear(Arguments rArgs);

.NET

CilError Clear(Arguments args);

Parameters

reserved_args

Not currently used, reserved for future use.

errorcode

An output parameter (return parameter in VB) that contains an error code from Table 1.

Return Value

Default CTI OS return values. For more information, see CIL Coding Conventions.

Remarks

In the case of a multi-party Conference call, calling Clear() results in all of the parties to the call being hung up. (If this is not the desired behavior, see the ClearConnection method.) Under certain switches the Clear request is made via a call whose status is LCS_CONNECT or LCS_INITIATE or it fails. Many other switches allow the Clear method to be called via a call whose status is LCS_ALERTING or LCS_HOLD. It can never be made via a call whose status is LCS_NULL indicating that it is already cleared.

The following events are received if this request is successful:

• OnClearCallConf event
• OnCallCleared event

The following events are received if this request fails:

• OnControlFailureConf event

Note	The Clear method is not supported on Unified CCE. Use of the Clear method with Unified CCE results in loss of third-party call control. To avoid this error, applications should use the ClearConnection method instead of Clear to hang up a call.

ClearConnection

If there are only two parties to the call, ClearConnection clears the call. However, for a multi-party conference call, only one connection is dropped, which is its own connection.

Syntax

C++

int ClearConnection()
int ClearConnection(Arguments & reserved_args);

COM

HRESULT ClearConnection (/*[in,optional]*/ IArguments *reserved_args, (/*[out, retval]*/ int * errorcode)

VB

ClearConnection([reserved_args As IArguments]) As Long

Java

int ClearConnection(Arguments rArgs);

.NET

CilError ClearConnection(Arguments args);

Parameters

reserved_args

Not currently used, reserved for future use.

errorcode

An output parameter (return parameter in VB) that contains an error code from Table 1.

Return Value

Default CTI OS return values. For more information, see CIL Coding Conventions.

Remarks

As with the Clear method, under certain switches you must make the ClearConnection request via a call whose status is LCS_CONNECT or LCS_INITIATE or it fails. Many other switches allow the Clear method to be called via a call whose status is LCS_ALERTING or LCS_HOLD. It can never be made via a call whose status is LCS_NULL indicating that it is already cleared.

The following events are received if this request is successful:

• OnClearConnectionConf event
• OnCallConnectionlCleared event

If this is a two party call, these events are followed by:

• OnCallCleared event

The following events are received if this request fails:

• OnControlFailureConf event

Conference

The Conference method either begins a new conference call or adds an additional call to an existing conference call. When it begins a new conference call, it combines an original two-party call with a two-party consult call (where the two calls have a common party) into a single three party call. Only the common party (which is called the "Conference Controller") can call this method to make the new conference call. You can call this method on either of the Conference Controller's calls.

Syntax

C++

int Conference();
int Conference(Arguments& optional_args)

COM

HRESULT Conference ( /*[in, optional]*/ IArguments *optional_args, (/*[out, retval]*/ int * errorcode )

VB

Conference([optional_args As IArguments]) As Long

Java

int Conference(Arguments optional_args)

.NET

CilError Conference(Arguments optional_args)

Parameters

optional_args

An optional input parameter, which is a pointer or reference to an Arguments array that contains a member with the string value that is the UniqueObjectID of the call to which this call is conferenced. If this argument is used, add it to the Arguments parameter with the keyword of "CallReferenceObjectID". This is only necessary in an environment where there are multiple held calls and the request is made through the talking call. If the request is made through a specific held call in this scenario, or if there are only two calls at the device, this parameter is unnecessary.

errorcode

An output parameter (return parameter in VB) that contains an error code from Table 1.

Return Value

Default CTI OS return values. For more information, see CIL Coding Conventions.

Remarks

Before making this request, the original call must be in the held state and the consult call in the talking state or the request fails. Therefore, if the calls are alternated (see Alternate), they must be alternated again to return the two calls to their appropriate states.

If there are only two calls at the device, you can call this method using either the current or held call. For switches which allow more than two calls at a device (for example G3), make this request through the desired held call to avoid the ambiguity caused by multiple held calls at the device. Otherwise, indicate the desired held call using the optional parameter.

You must make the Conference request via a call whose call status is LCS_CONNECT or LCS_HELD or it fails.

On certain switches (notably Unified CCE), only the Conference Controller (the party that first initiated the conference call) can add additional parties to an existing conference call.

The following events are received if this request is successful:

• OnConferenceCallConf event
• OnCallConferenced event

The following events are received if this request fails:

• OnControlFailureConf event

GetCallContext

Parameters

args

C++, COM, and VB: An output parameter containing a reference or a pointer to an Arguments array containing the call data, as described under Remarks.

Return Value

C++, COM, and VB: Default HRESULT return values. For more information, see CIL Coding Conventions.

Java/.NET: A reference to an Arguments array that, on return, holds parameters described under Remarks.

Remarks

This is a convenience method to call and get all of a call's CallVariables (1 through 10) and ECC Call Variables at one time. If only certain call variables are desired, call the appropriate GetValue method for each instead.

Access the data in the following way:

• To access the values for individual CallVariables from the arguments parameter, use GetValueString with either the keywords of "CallVariable1" through "CallVariable10".

To access ECC call data, use the following procedure:

• First, get the ECC variables as a whole from the arguments parameter, using GetValueArray with the keyword "ECC". This returns another Arguments array that is nested in the Arguments array returned from GetCallData.
• To access an individual ECC scalar variable from this Arguments array, use the appropriate GetValueString, GetValueInt, etc. depending on the variable's type, using the string keyword "user.VariableName".
• To access an individual ECC array variable from this Arguments array, use the appropriate GetValueString, GetValueInt, etc. depending on the variable's type, using the string keyword "user.ArrayName[n]", where n is a zero based integer that notes the offset in the array.

Hold

The Hold method holds a current call.

Syntax

C++

int Hold()
int Hold(Arguments & reserved_args);

COM

HRESULT Hold (/*[in,optional]*/ IArguments *reserved_args, (/*[out, retval]*/ int * errorcode )

• OnCallHeld event

The following events are received if this request fails:

• OnControlFailureConf event

MakeConsultCall

The MakeConsultCall method initiates the combined action of placing the associated current call on hold and then making a new call. By default, the call context data (including call variables) of the current call is used to initialize the context data of the new consultation call. The application can override some or all of the original call context in the consultation call by providing the desired values in this request.

The simplest form of the request only requires a dialed number and a consult type. The request can also include optional parameters, as listed in the following table.

Syntax

C++

int MakeConsultCall (Arguments& args))

SetCallData

The SetCallData method sets any or all of a call's CallVariables (1 through 10) and ECC data at one time.

Note

When writing a custom application, in any language, call variables are not blanked out if it they are set to a NULL value. While the application attempts to clear any call variable using a NULL value, the CTI OS server application ignores the NULL value call variables and does not pass them to the CTI Server application. As a result, the call variables set to NULL are not reset. To clear the value of a call variable, set its value to a blank character. Setting the call variable to a single space character places a space in the call variable's values for the duration of the call. This space is considered a NULL value by the application.

Syntax

C++

int SetCallData(Arguments& args)

COM

HRESULT SetCallData (/*[in]*/ args *arguments, /*[out]*/ int * errorcode)

VB

SetCallData (args As CTIOSCLIENTLib.IArguments, errorcode As Long)

Java

int SetCallData(Arguments rArgs)

.NET

CilError SetCallData(Arguments args)

Parameters

args

An input parameter of either a reference or a pointer to an Arguments array containing parameters described under Remarks for GetCallData.

errorcode

An output parameter (return parameter in VB) that contains an error code from Table 1.

Return Values

Default CTI OS return values. For more information, see CIL Coding Conventions.

Remarks

You must specify the data for all elements in the Arguments array, not just those elements that you want to change. Failure to do so causes the unchanged elements to disappear.

The following events are sent if this request succeeds:

• OnSetCallDataConf
• OnCallDataUpdate

The OnControlFailureConf event is sent if this request fails.

SingleStepConference

The SingleStepConference method initiates a one-step conference without the intermediate consultative call so that when the called party answers, they are joined in the current call. This method requires a DialedNumber argument. This method is not supported under all switches.

Calling this method causes the CTIServer to forward the request to the server application with the SessionID received in the OnStartRecordingConf event if non-zero, or if that SessionID is zero, to one or more server applications that have registered the "Cisco:CallRecording" service as described in the CTI Server Message Reference Guide (Protocol Version 14) for Cisco Unified ICM/Contact Center Enterprise & Hosted. It fails if there is no recording server available to CTIServer.

• The OnStopRecordConf event is received if this request is successful.
• The OnControlFailureConf event is received if this request fails.

Transfer

The Transfer method transfers a call to a third party. You can call this method on either the held original call or the current consult call. If the device has only these two calls, the optional parameter is not necessary. At the end of a successful transfer, both of these calls are gone from the device. For more information, see the Conference method.

Syntax

C++

int Transfer();
int Transfer(Arguments& optional_args)

COM

HRESULT Transfer ( [in, optional] IArguments *optional_args, (/*[out, retval]*/ int * errorcode )

VB

Transfer([optional_args As IArguments]) As Long

Java

int Transfer(Arguments rArgs)

.NET

CilError Transfer(Arguments args)

Parameters

optional_args

An optional input parameter containing a member with a string value that is the UniqueObjectID of the call that is participating in the transfer. If this argument is used, add it to the Arguments parameter with the keyword of "CallReferenceObjectID". This is only necessary in an environment where there are multiple held calls and the request is made through the current call. If the request is made through a specific held call in this scenario, or if there are only two calls at the device, this parameter is unnecessary.

errorcode

An output parameter (return parameter in VB) that contains an error code from Table 1.

Return Values

Default CTI OS return values. For more information, see CIL Coding Conventions.

Remarks

Before making this request, the original call must be in the held state and the consult call in the talking state or the request fails. Therefore, if the calls are alternated (for more information, see Alternate), they must be alternated again to return the two calls into their appropriate states.

If there are only two calls at the device, call this method using either the current or held call. For switches that allow more than two calls at a device (for example G3), make this request only through the desired held call to avoid the ambiguity caused by multiple held calls at the device. Otherwise, indicate the desired held call by using the optional parameter.

You must make the Transfer request via a call whose call status is LCS_CONNECT or LCS_HELD or it fails.

The following events are received by the transfer initiator if this request is successful:

• OnCallTransferred event
• OnCallEnd event
• OnCallEnd event
• OnAgentStateChange event
• OnTransferCallConf event

The OnControlFailureConf event is received if this request fails.
