[Asterisk-video] SIP call to a Radvision 3G Gateway

[aster vdo]

Hi,

i am trying to place a SIP call to Radvision 3G gateway.

The call setup is as follows.

asterisk <---------- SIP call over IP ---------> Radvison 3G
Gateway<----------------  3G Network -----------> End User on 3G


i was able to place a call successfully but the problem is that only audio
is getting played and the video does not appear.

Is there any extra setting i need to do on asterisk.

regards,
aster.
