I have the same problem on on of our systems, but i always thought it to
be a problem in the ATA's connected to this server.
(My customer has a lot of traffic on the lines and only sometimes hears
this problem).
It seemed to happen especially with loud woman voices, but i was unable
to reproduce it on command.
I have several other te410p's on different locations (with different
carriers), without those complaints.
Does this also happen on pri to pri calls for you ?
Maybe its a combination of carrier volume with the te410p ?

We are experiencing random talk off events when we hear a loud volume
event on the PSTN side of our calls. We do not always hear the
spurious DTMF, but I can see it in the console when I have the debug
and verbose levels turned up. We do however always have the
associated brief periods of silence that immediately follow.
Sometimes they are only a matter of seconds, other times they can be
as long as a minute. We hear it most often if the remote party is on
a cellular phone with a lot of background noise, or if a loud noise
happens during the call. Neither party can hear the other when this
happens. It almost reacts like an AGC circuit is muting the call.
We are using a Digium TE411P quad-span T1 card on 1.2.5. I called
Digium support and we have played with the VPM_DEFAULT_DTMFTHRESHOLD
in the WCT4XXP.C driver as recommended, and all the RELAXDTMF and GAIN
settings in Zapata.conf are set according to their recommendations.
Has anyone else experienced this, and if so, what have you done to
correct it?
