[Asterisk-Users] Random Disconnects - or ARE they?

[Bob McDowell]

Perhaps you can scale him back at the 79XX?  Not only might it solve the
problem, but I'll bet the people talking to him on the other end would
appreciate it as well...

On the Aastra 9133i, for example, you can provide gain settings in the
(mac).cfg file.

Subject: [Asterisk-Users] Random Disconnects - or ARE they?

I have one use on our PBX who has been experiencing seemingly random
disconnects. The user is on the same LAN as everyone else, using the
same type of phone (79XX loaded with SIP firmware) as everyone else. He
had some disconnects a few weeks ago, I suspected the phone, so I
swapped his with mine. I have since not had issues with his old phone,
however, he has had issues using mine. So, the problem seems to be not
with the phone, but with his station. I started thinking maybe the cable
is bad. I checked the network stats on his 79XX, and never see any
receive errors - perfect network performance. Also, the CLI has no
indication of an error whenever a disconnect occurs, it just looks like
a normal hangup of the Zap channel (TDM400P).

The ONLY difference between this user and everyone else is his extremely
loud talking. When I run ztmonitor it is obvious that he simply pegs the
meter. Either it reads peaked out or silence, whether he is speaking or
being quiet.

Is it entirely possible that he is driving the Zap channel so hard that
it either hangs up or causes the telco CO to hang up the channel? Is
there something else I should look at that might indicate what the
problem is? I am kinda pulling my hair out on this one, any help or
suggestions would be appreciated.
