I am doing a POC for one of my client. I have currently deployed CMS core and integrated it with the existing CUCM cluster. All configuration in CUCM and CMS are as per Cisco configuration guides. Integration between CUCM and CMS is only through SIP Trunk (for rendezvous calls) and CMS is not registered as conference bridge in CUCM. When calls are tried, audio is working but no video seen. CUCM version is 11.5 and CMS 2.2. Any known issue or am I missing any configuration. Thanks in advance.
