Direct SIP integration between CUCM and OCS 2007 R2
We have integrated OCS and CUCM through CUPS 7.x which is working fine, RCC from MOC, simultaneous ring on Cisco IP Phone and MOC client all this works fine.
What we want to do next is
Direct SIP integration between CUCM 7 and OCS 2007 R2 without CUPS and Mediation Server
Is this possible? I got information from Microsoft that CUCM is qualified for direct SIP integration with CUCM without CUPS or Mediation Server.
Ideally we want same extension number for IP Phone and MOC, simultaneous ring, RCC.
