Hi,

I use a simple scheme:


SIP video phone A (h264/Asterisk 1.8.11) <---IAX2 trunk----> SIP video phone B (h264/Asterisk 11.7.0)


When calls from A to B and vice versa drop on pickup.


On B side:

I have also tested with the following setup and video is displayed correctly (the only difference is the asterisk version of B)


SIP video phone A (h264/Asterisk 1.8.11) <---IAX2 trunk----> SIP video phone B (h264/Asterisk 1.8.20)



Any pointers to help me debug further please? Does had a similar problem? The videophones used A:Grandstream GXV-3000/3140 B:Grandstream GXV-3275


Thanks
