Adding a dial plan

Last Updated : Sep 18, 2026 |
Prolog information
Configure a dial plan for a certain call type and office location. You can also add SIP servers that the contact center uses for call routing. If you add a SIP server for a Public, Private, Emergency, Local, or Custom call type, you must specify agent profiles to which the configuration applies.
If you configure a dial plan for the reserved call type, you cannot add endpoints with extensions that match the specified dial plan parameters.
The minimum and maximum length of a dialed number or agent ID depends on the call type. The first character for the external-prefix call type can be an asterisk (*) or a pound sign (#). You can type the plus sign (+) as the first digit in the string for all call types. For example, for the deny call type, you can type +1900. The minimum and maximum length values of a dialed number or an agent ID include special characters.
  1. On the Configuration Server web portal, go to AdministrationSystemDial Plan Analysis.
  2. At the top-right corner of the Dial Plan Analysis page, click the the Add icon icon.
    STEP RESULT:
    Configuration Server displays the dial plan configuration fields.
  3. At the top half of the page, in the Dialed String Prefix field, type the digits that the contact center uses to identify dialed numbers or agent login IDs.
  4. In the Call Type drop-down list, select one of the call types to associate with this dial plan.
    ADDITIONAL INFORMATION:
    You can select one of the predetermined call types or configure your call type on the Dial Plan Call Types page.
  5. In the Min Length field, type the minimum length of the dialed number or agent login ID.
    ADDITIONAL INFORMATION:
    For custom call types, you can type a value from 1 to the value entered in the Max Length field.
    For more information about the minimum length value range for predetermined call types, see the dial plan configuration section in Administering Avaya Contact Center – Extended Capacity.
  6. In the Max Length field, type the maximum length of the dialed number or agent login ID.
    ADDITIONAL INFORMATION:
    For custom call types, you can type a value in the range from the value entered in the Min Length field to 24. For the external-prefix call type, the maximum length must match the Min Length value.
    For more information about the maximum length value range for predetermined call types, see the dial plan configuration section in Administering Avaya Contact Center – Extended Capacity.
  7. Do one of the following:
    • To apply the dial plan configuration to all agent profiles, select All Agent Profiles.
    • To apply the dial plan configuration to certain agent profiles, in Agent Profile(s), select one or several agent profiles.
    ADDITIONAL INFORMATION:
    You can configure agent profiles on the Agent Profiles page.

  9. In the Routing Mode drop-down list, select one of the following:
    • Priority Based: To distribute contact center calls equally between SIP servers in circular order.
    • Round Robin: To route contact center calls to SIP servers based on the server priority. If the first SIP server in the Destination SIP Server(s) section fails, the contact center starts routing calls to the next SIP server in the list.
  10. In the Destination SIP Server(s) section, in the SIP Server drop-down list, select a SIP server that the contact center uses for call routing.

    STEP RESULT:
    Configuration Server saves the dial plan configuration and redirects you to the Dial Plan Analysis page.
    For the Public, Private, and Emergency call types, if you do not set any SIP servers, Configuration Server displays a warning. Click OK to continue without configuring a SIP server.
