I seem to be in the same boat as Darren.

Asterisk 11.3 and 9971 cisco sip9971.9-2-4-19. Also tried sip9971.9-3-2SR1-1. (I have access to older firmware if needed)

Video and Presence don't seem to work together - If i set cisco_usecallmanager=yes then video doesn't work, else the presence features don't work. Also have the same problem of low video quality on the phones. I have tested by calling between two 9971 phones, with other Video enabled SIP phones, the Bria app for iPhone and Android...

When the video does work, it works only by me setting the phone on mute and back. I get the same functionality on another 11.3 instance that has not been patched.

Another thing that doesn't work as i expected is the DND key on the phones. Pressing that key as configured by FeatureID 130 puts the device in DND mode but doesn't signal change device or presence status on asterisk and as a result doesn't end up notifying other listeners on the network. Setting DND using the *76 feature code or the 760 dialplan as prescribed above sets the appropriate state on asterisk and all listeners, however that doesn't reflect on the device in any way - no DND animation and no BLF lights representing the DND status on the device that made the DND request.

Will keep looking for clues to what i may be missing and will post back if i find a way forward.

> Cisco phones appear to be unable to parse the existing PIDF XML being generated by Asterisk for presence notification.  I've attached a patch which produces well-formed (but incomplete) XML which will satisfy a Cisco phone.  The patch as supplied will successfully render a "busy" subscription, but does not send a subsequent "available" notification, so presence detection only half works currently.
> I suspect the next step might be to watch some CallManager SIP traffic to identify precisely what XML tags the phone is expecting in order to properly parse an available subscription, but I'm not in a position to do that.  I'll continue to work with this, though, and perhaps may be able to stumble upon the precise data the Cisco phone is looking for.
> {{****** ADDITIONAL INFORMATION ******}}
> I believe that this requires the Cisco phones be configured to use SIP TCP when connecting to Asterisk.
