I need to configure a call, in an UC500, between two IP comunicator with cisco Video advantage .
Voice calls between both IP communicators are Ok , but video advantage shows the same image in local and remote window. I seems like the ip comm or the UC 500 don't detect video advantage software.
Here is the intergration considerations
Cisco IP Communicator and Cisco Unified Video Advantage are supported only with H.323 Trunks and not supported with SIP Trunks
