Troubleshooting the Cisco Unified Videoconferencing 3500 MCU
Resolving Quality Issues in Cascaded Conferences
This section describes what to do if a cascaded conference suffers long delays or bad lip synchronization.
Possible Causes
Unsuitable topology used (for example, chain
topology used unnecessarily).
Resolving Endpoint Disconnection Issues
This section describes what to do if endpoints unexpectedly drop out of the MCU conference.
Possible Causes
Unreliable network link.
Resolving Unexpected Conference Termination
This section describes what to do if a conference on the MCU unexpectedly terminates.
Possible Causes
The Ad hoc conferences terminate when option in

Troubleshooting Guide for Cisco Unified Videoconferencing 3500 MCU Release 5.1
Resolving Quality Issues in Cascaded Conferences
Verification Steps
•
One single central MCU should invite all
other cascaded MCUs.
We recommend that you do not have more
•
than one level of cascaded MCUs.
Use a star topology, where the central MCU is
•
in the center of the star, and other cascaded
MCU modules are on the arms of the star.
Verification Steps
Check network link quality (round trip time
should be less than 300 msec).
Verification Steps
Set the Ad hoc conferences terminate when option
in MCU > Settings > Advanced to Last participant
leaves.
Check network link quality (round trip time
should be less than 300 msec).
