I have a CCMEv8 and a CUCMv8 connected via VPN site to site, the voice call are working, from the Cisco phones registered in the CCME to phones registered in the CUCM and vice versa. Now I am trying a video call, but the call is established only via audio, the video session is not established.
The CCME is added in the CUCM as H.323 Gateway, and the CCME has configured a dial-peer to CUCM. All traffic is permitted in the tunnel VPN.
How I can resolve this problem ?
