Modify a Dial Plan

 

Topic Last Modified: 2010-12-12

To modify an existing dial plan, perform the steps in the following procedure. If you want to create a new dial plan, see Create a Dial Plan.

  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 Dial Plan.

  4. On the Dial Plan page, double-click a dial plan name.

    noteNote:
    The dial plan scope and name were set when the dial plan was created. They cannot be changed.
  5. (Optional) In Edit Dial Plan, edit the Simple name field, which is prepopulated with the same name that appears in the Name field to specify a more descriptive name that reflects the site, service, or user to which the dial plan applies.

    importantImportant:
    The Simple name must be unique among all dial plans within the Lync Server deployment. It cannot exceed 256 Unicode characters, each of which can be an alphabetic or numeric character, a hyphen (-), a period (.), a plus sign (+), or an underscore (_).
    Spaces are not allowed in the Simple name field.
  6. (Optional) In the Description field, type descriptive information about the dial plan.

  7. (Optional) If you want to use this dial plan as a region for dial-in access numbers, specify a Dial-in conferencing region. If you do not want to use this dial plan for dial-in access numbers, leave this field empty.

    noteNote:
    Dial-in conferencing regions are required to associate dial-in conferencing access numbers with one or more dial plans.
  8. (Optional) In the External access prefix field, specify a value only if users need to dial one or more additional leading digits to get an external line (for example, 9). You can type in a prefix value of up to four characters (that is, #, *, and 0-9).

    noteNote:
    If you specify an external access prefix, you do not need to create a new normalization rule to accommodate the prefix.
  9. Associate and configure normalization rules for the dial plan:

    • To choose one or more rules from a list of all normalization rules available in your Enterprise Voice deployment, click Select. In the Select Normalization Rules dialog box, highlight the rules that you want to associate with the dial plan and then click OK.
    • To define a new normalization rule and associate it with the dial plan, click New. For details about defining a new rule, see Defining Normalization Rules.
    • To edit a normalization rule that is already associated with the dial plan, highlight the rule name and click Show details. For details about editing the rule, see Defining Normalization Rules.
    • To copy an existing normalization rule to use as a starting point for defining a new rule, highlight the rule name and click Copy, and then click Paste. For details about editing the copy, see Defining Normalization Rules.
    • To remove a normalization rule from the dial plan, highlight the rule name and click Remove.
    noteNote:
    Each dial plan must have at least one associated normalization rule. For details about how to determine all of the normalization rules a dial plan requires, see Dial Plans and Normalization Rules in the Planning documentation.
  10. Verify that the dial plan’s normalization rules are arranged in the correct order. To change a rule’s position in the list, highlight the rule name and then click the up or down arrow.

    importantImportant:
    Lync Server traverses the normalization rule list from the top down and uses the first rule that matches the dialed number. If you configure a dial plan so that a dialed number can match more than one normalization rule, make sure the more restrictive rules are sorted above the less restrictive ones.
    The default Prefix All normalization rule ^(\d{11})$ matches any 11-digit number. If, for example, you add a normalization rule that matches 11-digit numbers that start with 1425, make sure that Prefix All is sorted below the more restrictive ^(1425\d{7})$ rule.
  11. (Optional) Enter a number to test the dial plan and then click Go. The test results are displayed under Enter a number to test.

    noteNote:
    You can save a dial plan that does not yet pass the test and then reconfigure it later. For details, see Test Voice Routing.
  12. Click OK.

  13. On the Dial Plan page, click Commit, and then click Commit all.

    noteNote:
    Any time you create or modify a dial plan, you must run the Commit all command to publish the configuration change. For details, see Publish Pending Changes to the Voice Routing Configuration in the Operations documentation.
