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

<br>
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.<br>
