We are facing an issue. We have two SIP trunks, one from local provider another from international (only for international calls). And we have two different types of the phone registered with CME, 7945 and 8845. SIP Trunk also terminated on the same CME. The international calls are failing when the video is enabled on 8845 (getting reorder tone, cause code=3). The call is successful when the video is disabled. 7945 has no issues for local or international calls.
I have used the following to disable the video codecs in the SIP invite. The call is going through but only one-way audio.
voice class sip-profiles 1
request ANY sdp-header Video-Attribute remove
request ANY sdp-header Video-Media modify "m=video(.*)" ""
request ANY sdp-header Video-Bandwidth-Info remove
Any help is greatly appreciated.
