Administering Communication Manager

Last Updated : Jun 20, 2013 |

Before you begin

Communication Manager must connect with Session Manager in a non-IP Multimedia Subsystem (IMS) signaling group for Call Center functionality.

Ensure that the field option in the IMS Enabled field on the SIP Signaling Group screen is n to prevent Feature Invocation Failure when an agent logs in to the system.

Verify the field settings and values in the following fields on the System-Parameters Customer-Options screen:

  • ISDN-PRI

  • IP Trunk

  • Expert Agent Selection (EAS)

  • Maximum Administered SIP Trunks

  • Maximum Off-PBX Telephones-OPS

Ensure that the field option in the DID/Tie/ISDN/SIP Intercept Treatment field is attd and the Trunk-to-Trunk Transfer field is restricted.

About this task

You can use SIP agents when you administer Communication Manager as an evolution server.

As an evolution server, Communication Manager uses the full-call model. In the full-call model, call processing is a single step procedure, that is, Communication Manager processes the origination and termination parts of the call without a break.

For information about IMS signaling flow and full-call model, see Implementing End-to-End SIP.

Procedure

  1. Change the dialplan analysis.
  2. Change the Feature Access Codes (FAC) for Automatic Alternate Routing (AAR) and Automatic Route Selection (ARS).
  3. Add a SIP domain in each network region, and administer an IP node name for the IP address of the Session Manager Security Module.
  4. Add a SIP signaling group for each Session Manager Security Module. For message interchange between Communication Manager and the SIP server, select y in the Peer Detection Enabled field on the Signaling Group screen.
  5. Add a trunk group of type SIP for call routing from Communication Manager to Session Manager.
  6. Administer the route pattern, and add the route pattern number as a proxy route.
  7. Administer private numbering plan.
  8. Administer the uniform dial plan.
  9. Administer AAR and ARS.
  10. Save translations.
