Video Does Not Work

Problem: Video does not work, but audio does.

Solution: Try pressing the hold button and then the resume button on the phone. This can sometimes clear up transient problems related to video.

Possible Cause: The meeting scheduler cannot host video meetings, so video is not enabled for the meeting.

Solution: Check the video usage setting in the user profile of the meeting scheduler.

Possible Cause: In Cisco Unified Communications Manager, the DTMF signaling method for the SIP trunk to Cisco Unified MeetingPlace is configured to use RFC 2833.

Solution: Set the DTMF signaling method field to No Preference.

Problem: A video conference the call drops after 20 seconds. There is no Video or Audio on during that time. SIP B2BUA log from Infocap shows that CUCM send TIAS with negative value, [.INFO] [..MESSAGE] b=TIAS:-1000, and this is due to "Video Call Bandwidth" was set to NONE in Region setting.

Solution: Set the correct value for "Video Call Bandwidth" in Region setting in CUCM.

Poor Video Quality

Problem: The video has a pixelated image or poor quality.

Possible Cause: Network issues are causing packet loss between the endpoint and Cisco Unified MeetingPlace.

Solution: Check the network for and correct any packet loss or excessive bandwidth utilization along the path between the video endpoint and Cisco Unified MeetingPlace.

Possible Cause: (CSCso95109) The input stream is from the Cisco Unified IP Phone 7985. This potentially affects all video calls with Cisco Unified MeetingPlace when the Cisco Unified MeetingPlace global video mode is set to "standard rate" (384kb).

Solution: In the Administration Center, set the global video mode field to High rate.

Solution: For full compatibility with Cisco Unified MeetingPlace, upgrade the Cisco Unified IP Phone 7985 to application load 4.1(7) or later.
