Branch SIP Trunk administration for PSTN connectivity

Last Updated : Jun 30, 2017 |

About this task

The following are the high level administration steps for administering branch SIP trunks with SIP Service Provider.

You must first administer the service providers interface as the new SIP entity. You must also create SIP entity links between:

  1. The associated Branch Session Manager and one or more core Session Manager instances.

  2. The service provider SIP entity and the associated Branch Session Manager.

Note:

You can administer direct SIP Entity Links between Branch Session Manager and other types of SIP Entities – similar to Session Manager. For instance, you can directly connect Messaging Service to Branch Session Manager in Branch.

Procedure

  1. Add a new SIP Entity with type Service Provider. Use the IP address of the service provider equipment.
  2. Modify the Adaptation as needed.
  3. Add a SIP Entity link between the Service Provider and the Branch Session Manager.
  4. Add Entity Links between the Branch Session Manager and the core Session Manager instances.
    Note:

    Links must be available between the Branch Session Manager and any core Session Manager instances that are controllers for users on the branch. For call routing, at least one link must be available between the Branch Session Manager and a core Session Manager to make calls to the core.

  5. Administer SIP Monitoring for all Branch SIP Trunks.
