Video Calls between 2 callmanager express through Gatekeeper

Hello everybody.

I have a lab with 2 callmanager expresses both registered to Gatekeeper. I can make a video call inside each callmanager express but I'm not able to make video calls when I call from callmanager express A to B and viceversa, I just get audio in the calls.

What do I need to configure inside the Gatekeeper to send the video between callmanagers?

Any Ideas.

Regards

Walter Flores

CME to H323 to CME is a supported video call flow:

http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmevideo.html

A couple of things to check:

a. Enable H323 slow start under Voice Service VoIP or Voice Class

voice service voip

supplementary-service h450.12 advertise-only

h323

call start slow

b. Make sure there is enough bandwidth for a video call both in configuration and WAN bandwidth availability

Hope this helps.

Regards,

Michael

Call Manager Express does not support video services and I am not aware of any plans to introduce video into Call Manager Express.

Video is supported in Call Manager
