We are having random no-way audio problems with some of the phones (7960's mostly, no reports of other models) on our CM4.1 system. The problem creeps up every 5-7 days, and only appears to affect some of the phones.
Yesterday morning, I had two different buildings complain of the same problem- Incoming calls ring, but nobody is there and outgoing calls not ringing out. (When they called my cell, it rang, but they never heard the ringback tones.)
Yesterdays problem was only reported by two of nine buildings.
Resetting a phone doesn't change anything. If I reset the VG200, the problem goes away for another 5-7 days.
When I looked at the VG200 yesterday, there were only 4-6 calls in progress at the time.
The VG200 has been in service for nearly seven years, and no changes have been made recently. The last changes were to add dial-peer statements for new buildings that were brought online with IP phones.
The IOS version on the VG200 is 12.2(4)T1, it is configures as an H323 gateway in CallManager. Our CM is version 4.1(3)sr3b.
Does anyone have suggestsion on what to monitor or check to locate the source of the problem?
Hopefully I've given enough information to accurately describe the problem.

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
