When server A’s SIP user called to another server B’s SIP user, they could talk and see each other’s video after clicking ‘Start Video’ on X-Lite.
However, when server B’s SIP user called to server A’s SIP user, they could talk but could not see the video even they had clicked the ‘Start Video’ on X-Lite.
The X-Lite was sending the video but no video was seen on each side.
The SIP debug message appeared normally and it could detect the audio and video format.
Note: server A is Asterisk 1.4.21.2 and server B is Asterisk 1.6.0.9
Could there be any version incompatibility problem?
Please advice us.
Thanks in advance.
