Video Endpoint Gets One-Way Video or No Video

Problem: A video endpoint gets no video or gets only one-way video.

Possible Cause: The video endpoint does not support escalation to video via H.323 Empty Terminal Capabilities Set (ECS) or SIP re-INVITE after the voice call is established. This can result in either partial or complete lack of video reception after connecting to a meeting.

Solution: Check with the endpoint vendor for a firmware update.

Solution: Use the video terminal in direct-to-meeting mode.

Call is Dropped When Entering a Meeting, Entering a Breakout Session, or Entering #31 to Dial Out

Problem: A call is dropped when:

  • Video endpoint is about to enter a meeting.
  • Video endpoint is about to enter a breakout session.
  • Video endpoint user enters #31 in the TUI to initiate a dial-out call.

Possible Cause: The video endpoint does not support media transfer via H.323 Empty Capabilities Set (ECS) or SIP re-INVITE.

Solution: Check with the endpoint vendor for a firmware update.

Solution: Use the video terminal in direct-to-meeting mode. See How to Configure Video Terminal Profiles. Also:

  • Do not attempt to move the video terminal into a breakout session.
  • Do not initiate dial-out calls from the video endpoint by entering #31.



Jumpy Video

Problem: The video display appears to be unstable.

Possible Cause: When the Cisco Unified MeetingPlace global video mode is set to standard rate, and and video terminals are using the H.264 codec, Cisco Unified MeetingPlace negotiates the video connection at 15 frames per second, which is consistent with the H.264 Level 1.2 specification. However, many video terminals ignore the frame rate limitation for H.264 Level 1.2 and send frames at a higher rate. This overloads the Cisco Unified MeetingPlace video blade and results in corrupted video output. Note that the effect may be observed on terminals other than the one causing the problem.

Solution: Identify suspect terminals and check with the endpoint vendor for a firmware update.

Solution: Set the Cisco Unified MeetingPlace global video mode to high rate, or configure the video terminals to use H.263 instead of H.264.
