With Lync Server 2010, the called party’s phone number (that is, the phone number called) can be translated from E.164 format to the local dialing format that is required by the trunk peer (that is, the associated gateway, private branch exchange (PBX), or SIP trunk). To do this, you must define one or more translation rules to translate the Request URI before routing it to the trunk peer.

Lync Server 2013 introduces the option to also translate the calling party’s phone number (that is, the phone number that the caller is calling from) from E.164 format to the local dialing format that is required by the trunk peer. For example, you can write a translation rule to remove +44 from the beginning of a dial string and replace it with 0144.

To configure Caller ID by using Lync Server Control Panel

  1. Log on to the computer as a member of the RTCUniversalServerAdmins group, or as a member of the CsVoiceAdministrator, CsServerAdministrator, or CsAdministrator role. For details, see Delegate Setup Permissions.

  2. Open a browser window, and then enter the Admin URL to open the Lync Server Control Panel. For details about the different methods you can use to start Lync Server Control Panel, see Open Lync Server Administrative Tools.

  3. In the left navigation bar, click Voice Routing, and then click Trunk Configuration.

  4. On the Trunk Configuration page, double-click an existing trunk (for example, the Global trunk) to display the Edit Trunk Configuration dialog box.

  5. To configure caller ID presentation:

    • To choose one or more rules from a list of all translation rules available in your Enterprise Voice deployment, click Select. In Calling number translation rules, click the rules that you want to associate with the trunk, and then click OK.

    • To define a new translation rule and associate it with the trunk, click New. For details about defining a new rule, see Defining Translation Rules in the Deployment documentation.

    • To edit a translation rule that is already associated with the trunk, click the rule name, and then click Show details. For details, see Defining Translation Rules in the Deployment documentation.

    • To copy an existing translation rule to use as a starting point for defining a new rule, click the rule name and click Copy, and then click Paste. For details, see Defining Translation Rules.

    • To remove a translation rule from the trunk, highlight the rule name and click Remove.

    Warning:
    Do not associate translation rules with a trunk if you have configured translation rules on the associated trunk peer, because the two rules might conflict.
