asterisk users - Nov 2009 - Crosstalk - Is there a debug option for logging this?

Hi All,

I'm struggling with an intermittent crosstalk issue resulting in a
caller's
audio being broadcasted to other calls (only one way as they are unable to
hear the others listening in).

Doing do diligence I've scoured the web in hopes of triaging the issue.

So my thoughts are leaning towards this NOT being an Asterisk issue, but
instead being related to the telco (PRI) config...however without proper
logging this is a guess.

Is there a debug option in which I can see how Asterisk is routing the audio
for callers?  This would at least allow me to capture logging of the call
routing to determine if Asterisk is doing this or if it's occurring outside
of my control.

Crosstalk like this isn't a common occurrence, especially on digital
audio paths.

I would lean that same direction, but it's not a common problem to see
on a PRI, so don't be surprised if your telco's first reaction is
"It
can't be us... go talk to your PBX vendor".

Type "core show channels" at the Asterisk CLI to see each channel, and
what it's being bridged to.

This may be a long shot... I have experienced this when two SIP phones
had the same IP address (a bug by itself of course). Now, obviously the
SIP phone should not just play any random audio that someone throws at
it, but apparently life is not so simple.
