    Step 4

    Select the appropriate user ID from the Owner User ID drop-down list.

    Note

     

    Only users for whom you enable mobility are available from the Owner User ID drop-down list.

    Unified Communications Manager populates the Device Name field with the user ID and a CTRID prefix, for example, CTRIDusername.

    Step 5

    Edit the default value in the Device Name field, if appropriate.

    Step 6

    Enter a meaningful description in the Description field.

    Note

     

    Cisco Jabber displays device descriptions to users. If Cisco Jabber users have multiple devices of the same model, the descriptions from Unified Communications Manager help users tell the difference between them.

    Step 7

    Ensure that you select an appropriate option from the Rerouting Calling Search Space drop-down list in the Protocol Specific Information section.

    The Rerouting Calling Search Space drop-down list defines the calling search space for rerouting and ensures that users can send and receive calls from the CTI remote device.

    Step 8

    Configure the remaining fields in the Phone Configuration window. For more information on the fields and their configuration options, see Online Help.

    Step 9

    Click Save.

    The fields to associate directory numbers and add remote destinations are displayed in the Phone Configuration window.


    Add Directory Number to a Device

    A directory number (DN) is a numerical address that is configured as a line on the CTI remote device. A DN typically represents the primary work number of a user (for example, 2000 or +1 408 200 2000).


    Note


    • The Calling Search Space (CSS) and partition of DN are mandatory on devices.

    • The CTI Remote Device should not block its own DN. The CSS is important for the CTIRD device to reach its own DN.


    Follow these steps to add a directory number to a CTI remote device.

    Procedure


    Step 1

    Locate the Association Information section in the Phone Configuration window.

    Step 2

    Add Remote Destination

    Use the following procedure to add a remote destination is a numerical address or directory URI that represents the other phones that the user owns (for example, a home office line or other PBX phone). A remote destination may be any off-cluster device. Unified Communications Manager automatically applies application dial rules to all remote destination numbers for CTI remote devices. By default, four remote destinations are supported per device. You can set the maximum number to 10 remote destinations per device in End User Configuration window.


    Note


    You can determine which remote destination the Jabber client has set as Active by opening the Phone Configuration window from the Cisco Unified Communications Manager Administration interface.



    Note


    Unified Communications Manager users can add remote destinations through the Cisco Jabber interface. For more information, see the Cisco Jabber for Windows Installation and Configuration Guide.

    • Unified Communications Manager automatically verifies whether it can route calls to remote destinations that Cisco Jabber users add through the client interface.

    • Unified Communications Manager does not verify whether it can route calls to remote destinations that you add through the Cisco Unified Communications Manager Administration interface.

    The End User Configuration window appears, and the associated device that you chose appears in the Controlled Devices pane.

    CTI Remote Device (CTIRD) Call Flows

    Unified Communications Manager supports the separate calling party number and billing number feature when users are added as CTI Remote Device. Each CTI Remote Device is configured with the user directory number (DN) (for example, 2000) and a remote destination that represents any off-cluster device (for example, a PBX phone with the number +1 408 111 1111).

    When a call is initiated from the PSTN network to a CTIRD line, Unified Communications Manager looks for FROM and PAID header information. The FROM header contains the external presentation name and number and PAID contains the identity of the user (that is a user’s DN or DDI).

    If FROM and PAID headers have different numbers and Enable External Presentation Name and Number check box is checked in its SIP profile and Display External Presentation Name and Number service parameter value set to True, then Unified Communications Manager displays the FROM header information on the called device. In the same way, if any one option is disabled,Unified Communications Manager displays PAID header information on the called device.

    Similarly, in the outgoing call scenario a user calls from Remote Destination (CTIRD line) configured with External Presentation Name and External Presentation Number on Directory Number configuration page to a PSTN network through a SIP trunk with Enable External Presentation Name and Number configured in its SIP profile. Then, Unified Communications Manager send the External Presentation Information configured on the Directory Number Configuration page in the FROM header of the outgoing SIP message to display on the called device.

    If Enable External Presentation Name and Number check box is unchecked, then Unified Communications Manager sends the directory number information in the FROM and PAID to display on the called device and configured External Presentation Information in the X-Cisco-Presentation header.

    If you check the Anonymous External Presentation check box, the configured External Presentation Name and Number are removed from the respective fields and external presentation displayed as anonymous on the called device.

    For more details on Configuring External Presentation Information, see the Configure Directory Number chapter in the System Configuration Guide for Cisco Unified Communications Manager.

    Extend and Connect Interactions

    Table 1. Extend and Connect Interactions

    Feature

    Interaction

    Directory URI Dialing

    Configure a Directory URI as the DN, remote destination, or both for the CTI remote device.

    Unified Mobility

    Extend and Support does not support moving active calls between a Cisco Unified IP Phone and a remote destination.

    If you want the capabilities of both Unified Mobility and Extend and Connect, you can configure the same remote destination on the Remote Device Profile and CTI Remote Device types when the Owner ID of both device types is the same. This configuration allows Cisco Mobility features to be used concurrently with Extend and Connect. The ability to configure the same remote destination on both device types is supported using Cisco Unified Communications Manager Release 10.0(1) or later.

    Do not configure remote destinations that are used with the Cisco Extend and Connect feature on Cisco Dual-mode for iPhone, Cisco Dual-mode for Android, and Carrier-integrated Mobile device types. Do not use prefixes to differentiate the same remote destination address. For example, 91-4085555555 and +1-4085555555 are treated as the same number.

    Hunt List

    The Extend and Connect feature allows users to receive hunt calls on remote destination phones under the following conditions:

    • The user has a Cisco Unified IP Phone.

    • The Cisco Unified IP Phone is available to answer hunt calls (logged-in/HLog).

    • Cisco Jabber is running in Extend and Connect mode.

    CallerID Information

    • The incoming caller ID information (name and number) is displayed on the Jabber client.

    • This information may also be displayed on the device, depending on your carrier and trunk configuration.

    • Outbound Dial Via Office calls to the remote destination display Voice Connect as the name and the trunk DID as the number.

    • Configure the trunk DID in the Unified CM Trunk Pattern, Route Pattern, or Cisco Gateway. This configuration may also be assigned by the carrier. The number field may display as blank if the trunk DID is not configured.

    • Outbound calls to the desired party display the CTI Remote Device Display Name and Directory Number (DN) as configured in Unified Communications Manager.

    • Remote destination numbers are never displayed to the called party.

    Extend and Connect Restrictions
