Hi,

if you are getting a black screen on the phone then you may be running into the following issue, as described in the release notes for this firmware

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cuipph/9971_9951_8961/firmware/9_4_1/english/release_notes/P567_BK_84CD4C2B_00_8961_9951_71-release-notes-9_4_1.pdf

"Cisco Unified IP Phones 9951 and 9971 One-Way Video Calls:

Because of limitations in the H.264 video signaling standards, Cisco Unified IP Phones 9951 and 9971 may not correctly display video that is received from devices supporting resolutions greater than 640 x 480. In this case, the user sees a black video screen. To ensure that video from such devices displays properly on the IP phone, configure high definition phones and Cisco Unified IP Phones 8961, 9951, and 9971 into different call regions and limit the video bandwidth to 384 kb/s when calling between regions."

I am facing the same problem, with the same scenario. Can you tell me if you got any solution?

You can try unchecking Media Termination Point Required on the phone and then check. Also please make sure there is no bandwidth restriction there for the video calls.
