Cisco Unified Camera on 9971 - Intra-region calls falling back to audio, inter-region works

[nbourke2000]

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'm wondering if any kind soul could point me in the right direction to troubleshoot this.

I've just noticed this in the SIP INVITES themselves in RTMT:

Doesn't work:

m=video 0 RTP/AVP 31 34 96 97

c=IN IP4 0.0.0.0

Works:

m=video 8422 RTP/AVP 97

c=IN IP4 10.10.12.125

Still no closer to the cause of this.

Apologies. Posted prior to noticing that Video over IP would be a more appropriate place.
