NRS configuration

The Server IP running the MCM application (generally an Office Communications Server 2007 Proxy) must be configured on the NRS as a dynamic SIP endpoint, or gateway, and not as a collaboration server.

An Office Communications Server Service Domain must be created for the Signaling Server and MCM. The Signaling Server and MCM register to the Office Communications Server Service Domain on the NRS. The Service Domain between the NRS and the Office Communication Server may or may not match the domain name of the Office Communications Server.

The MCM is configured to register with End_Point_Name@Service_Do- main_Name, where the ‘Service Domain Name’ matches the Service Domain configured on the NRS

Office Communications Server Service Domain

In Office Communications Server Service Domain, the NRS is configured with the matching Service Domain of ocs2007a.corp.nortel.com.

The L1 and L0 Domains must also be configured and match what the CS 1000 is configured under SIP URI Map. Dynamic Gateway endpoints must be configured for the CS 1000 and the MCM with appropriate dialing plan entries.
