Displaying Statistics for a Participant
You can view statistics about the video and audio streams between individual participants (endpoints) and the MCU
by choosing this option:
by choosing this option:
1.
Go to Conferences.
2.
Click a Conference name and then click on a participant's name.
3.
Click the Statistics tab.
If the participant is participating in the conference using audio only, the values for the video settings are not
populated.

When examining media statistics for a conference's

so a different, more limited, set of information is displayed. In this case, the MCU shows how many streams of each
outgoing audio and video format are being transmitted.

Received jitter
The apparent variation in arrival time

The jitter buffer shows the current playout
delay added to the media to accommodate the
packet arrival jitter. Large jitter values indicate
a longer buffer.
