Video Over VPN between CCM and CCME using Trunk

Unanswered Question


I have 2 sites one with CCM 6.1 and another CCME 4.3

Between the two sites, VPN tunnel is established over the Internet.

Both way calls are working successfully.

Customer wanted to explore whether video will work in this scenario with Cisco Video advantage at both location.

Service Parametersare fine tuned:


•Media Exchange Interface Capability Timer

•Media Exchange Timer

to 25 but still the video doesnt work.

Any one else has configured like this over a VPN tunnel. Anything else to check ?

By default all IP traffic is permitted through a VPN tunnel except broadcast and multicast traffic. It basically is a matter of how the video software you are using works. If it is a multicast application then it will not work through an ipsec tunnel, if it is a unicast application then it should be able to work.

Also if this video is on the Internet tries to enable split tunnel on the VPN endpoint. Now if the issue is with a video that is on the PC, this might be because a software corruption of the OS, so try reinstalling the VPN Client software
