Audio Problems
The following sections describe how to resolve audio problems.
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.
Choppy Speech
Problem
A user complains of choppy speech on a call.
Cause
There may be a mismatch in the jitter configuration.

Check the AvgJtr and the MaxJtr statistics. A large variance between these statistics might indicate a problem
with jitter on the network or periodic high rates of network activity.
