• Three different modes: Proxy All, Redirect, and Proxy SIP Gateway
Calls

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
Figure 60
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.
