We just finished testing the Cisco 8945 IP phone with CME using SCCP and it worked great.  Point to point video works flawlessly.  A few things to note in setting up these phones:

1. Make sure you add the “video” command under telephony-service as well as under the ephone.
2. We found that we could not call out our PRI with these phones once video was enabled.  We had to add  “bearer-cap Speech” under the voice-port to force speech only out the PRI.  (The phones were trying to advertise video capabilities out the PRI and our service provider didn’t like that!)
3. Although the phones are capable of sending and receiving 640×480 (VGA) video we were noticing that the max we were getting was 325×288 (CIF) resolution.  We found that VT Advantage (which is what CME uses) maxes out at CIF resolution per this document.
   
4. Bluetooth works great, setup was very easy!
5. You can’t change the background on this phone — dissapointing!
