CallManager, 7985 and Radvision Scopia MCU

[olek]

Hi all,
I have a CallManager 4.1 with a configured trunk to a Radvision iView Suite Gatekeeper, there is a Route Group/List, Route Pattern and Translation Pattern configured on CCM. I can call from a Cisco ip phone to an Aethra endpoint registered with the GK. Calls from Aethra endpoint to ip phone also work. But calls between the ip phone and the mcu are made with no video (both initiated from the ip phone and the mcu).

Any suggestions?

Are you placing 64k bonded calls to the MCU or 56k voice calls?

Aethra codecs are pretty good about being able to auto downspeed as well as support bonding mode 2.

I use only H.323 (ip) calls. Audio-only conferences work well. On the Radvision MCU in conference control, connection statistics show that there are no packets sent containing video from the ip phone to the mcu and video codec info after few seconds since the connection is made changes from H.263 to Invalid. Also I see black screen on the ip phone. There is no welcome screen from the mcu on the ip phone either.
