Adding a SIP signaling group

Last Updated : Sep 21, 2023 |

Procedure

  1. On the Communication Manager SAT interface, type add signaling-group next, and press Enter.

    The system displays the SIGNALING GROUP screen.

  2. Note the value of the Group Number field.
  3. In the Group Type field, type sip.
  4. In the IMS Enabled field, type one of the following:

    • Type y to configure Communication Manager as a feature server.

    • Type n to configure Communication Manager as an evolution server.

  5. In the Transport Method field, type one of the following:

    • Type tls if the calls are secure calls.

    • Type tcp if the calls are not secure calls.

  6. In the Peer Detection Enabled field, type y.
    Note:

    This setting results in Communication Manager and the connected SIP server exchanging messages. The value for Peer Server changes to SM when the SIP signaling group is activated.

  7. For the trunks connected to Session Manager, perform the following steps:
    1. Set the value of the Peer Detection field to n.
    2. Set the value of the Peer Server field to SM.
  8. In the Near-end Node Name field, type procr.
  9. In the Far-end Node Name field, type the name of the Session Manager security module.
  10. In the Far-end Network Region field, type the IP network region number used in the Administering an IP network region procedure.
  11. In the Near-end Listen Port field, type a port number other than the port number defined in the IMS signaling group.

    For example, 5070.

  12. In the Far-end Listen Port field, type the port number that you typed in the Far-end Listen Port field on the IP NETWORK REGION screen.
  13. In the Far-end Domain field, type the domain name associated with Session Manager.
  14. To enable incoming dialog loopbacks, in the Incoming Dialog Loopbacks field, type allow.
  15. In the Enable Layer 3 Test field, type y.

    The system displays the Enable Layer 3 Test field when you type a value in the Far-end Node Name field.

    Important:

    If the value of Enable Layer 3 Test field is n, Communication Manager does not monitor the links. This test is required for the trunks connected to Session Manager. If you disable this test, maintenance software removes the trunks out of service.

  16. In the Initial IP-IP Direct Media field, type y or n, depending on the requirement of the Direct Media feature.
  17. To configure Communication Manager as an evolution server, in the H.323 Station Outgoing Direct Media field, type y.
  18. Save the changes.
