We are experiencing an issue with our Cisco 9971 and 8945 phones where
H264 video calls are connecting at 176x144 resolution instead of
640x480. Soft clients can connect at higher resolutions and the 9971
can even receive video at a higher resolution (although it still sends
176x144).
I contacted one of the developers and he suggested the passthrough of
SDP attributes is not working correctly. Has anyone else experienced
this problem? We're running Asterisk 11.8.1.
Below are the video parts of the sip debug for one of the phones during
a video call. Should I be seeing the "a=imageattr" in the SIP OK message?
It looks as though the passthrough for "fmtp" is indeed working but as
the "imageattr" attribute is currently unsupported/not used/not passed
through it is probably causing your resolution problem.
