[asterisk-users] Dropped Call Problem -- Looking for ideas and a consultant.

[Mark Engelhardt]

Hello Everyone.

We have:

Asterisk 1.4.21.2
zaptel-1.4.11
libpri-1.4.5
Sangoma A101D Connected to a PRI
Cicso 7960G phones (About 30 of them)

We have a problem with dropped calls that has going on for a long  
time.  We get up to 5 dropped calls on a bad day. They all seem to be  
incoming calls.

I have a recording of what my users report a dropped call sounds like  
right before it drops

Please have a listen to the recording and tell me what you think it  
means

I am looking for any ideas as to what I should do to track this down.  
I would love a lead on a good consultant who can help fix this.

Mark
