Hi Craig,
Yes, this is phone is supported with CME.
The bandwidth for video is dependent upon how much movement is in the frame.
When I was testing this if there wasn't much movement it would drop to about 50 kbsec but could hit up to 500 kbsec or so with the codec we were using (h.264 I believe).
The configuration couldn't be easier either:
telephony-service
video
ephone 1
video
ephone 2
video
Done.
hope it helps.
