Cause
The frame rate of the received video is low.
Solution
Check the rate by navigating to Administrator Settings > Status > CallStatistics > Video > Video Statistics
and checking the Rcvr Frame Rate field. Frame rates of fewer than 15 fps result in slow-moving video.
Audio/Video Is Not Synchronized
Problem
Audio/Video synchronization is poor.
Solution
To resolve synchronization issues:
•
Check whether RTCP is enabled in Cisco Unified Communications Manager.
•
Check for a degraded network connection by navigating to Administrator Settings > Status > Call
Statistics > Video > Video Statistics and checking the Avg Jitter and Max Jitter values.
•
Place the call on hold and then resume the call to restore audio/video synchronization.
No Audio
Problem
The recipient endpoint only sees a mute image.
Solution
If Auto Transmit Video is set to Off, the camera automatically transmits the mute image. The illuminated red
LED on the top of the camera indicates that the video is muted. Set the Auto Transmit Video setting to On
to restore video on the other side.
No Speech Path
Problem
One or more people on a call do not hear any audio.
Solution
When at least one person in a call does not receive audio, IP connectivity between phones is not established.
Check the configuration of routers and switches to ensure that IP connectivity is properly configured.
