[cisco-voip] Call terminated while leaving voicemail

[Kevin Thorngren]

Hi Mike,

This may be a one way audio issue.  You can try using the AudioStat 
tool that is in the Tools Depot to log the calls.  It may provide you 
with a quick reference to find the calls that did not record.  Of 
course a packet capture of the Unity server when the problem happens 
will provide a great deal of information.  This will help you to see if 
the audio is making it to the server to determine if the problem is in 
the network or with the server itself.

My question about "perceived disconnect" is to get a better 
understanding of the issue.  Sometimes the users say the call was 
disconnected but in reality the call is still up but due to what the 
user experiences the feel the call was disconnected.  This is good to 
know but is hard to define.

Kevin
