I have a small callmanager 8 setup with 9971 cam phones and 3rd party conference room VTC kit. Last week I set up mobility & SNR for my users. I've noticed since then that calls from the 3rd party VTC kit to the 9971s work perfectly with video, but calls from 9971 to 9971 fall back to audio only. This now impacts phones with DNs which SNR was not set up on.
I've searched everywhere but documentation on the Cisco Unified Camera seems to be restricted to the 9971 admin guide.
I've just noticed this in the SIP INVITES themselves in RTMT:
m=video 0 RTP/AVP 31 34 96 97
c=IN IP4 0.0.0.0
m=video 8422 RTP/AVP 97
c=IN IP4 10.10.12.125
Still no closer to the cause of this. Hopefully some kind soul could point me in the right direction to troubleshoot this.
have 9971 to 9971 video calls ever worked?
if your locations and regions are set up properly, and the profiles for 9971 has video enabled on the base phone, phone to phone will work fine. Also, make sure the usb port on the phone for the video camera is enabled in the base settings for the phone, or in the profile itself, whichever you're using.
