[Asterisk-Users] RE: Voice calls sent to fax extension

[Colin Anderson]

yes. Wind whistling in a car, female voices at a particular pitch and
volume, fax machine running in the background of a voice call with the
speaker on. It happens. Whether this is a problem or not depends on your
pain threshold. I get a couple reports a week, which means that it actually
happens ten times a couple times a week, so twenty times a week, and I
process ~20K calls a week, so it happens to me .1 % of the time. Is this a
problem for me? Nah. Is it a problem for you? Maybe - what's your pain
threshold?

ps fwiw, this behavior will happen with any device that listens inline for a
CNG tone, so it's not just an Asterisk thing

I thought it might be an inadvertent button press, but none of the keys
(on my phone at least) are recognized by Asterisk as fax tones.  This
has happened to two different users getting calls from different people
using different equipment.  Does anyone else see this behavior
occasionally?

Maybe their fat jowls hit a few buttons on the keypad and sent the fax
tone down the line and they didn't realize it?

I have a situation that has repeated itself a few times.  Someone calls
into Asterisk and is connected with a voice extension.  At some point
during the call, the log shows "chan_zap.c: DTMF digit: f on Zap/2-1".
At this point, the call is redirected to receive a fax and the Asterisk
voice extension is hung up.  The users report that there were no
noticable tones heard just before the cutover, so I'm not sure what's
going on.  Is there a way to disable detection of faxes after the
voicecall is initiated?  We're running a Digium card to convert our
analog trunks if that makes any difference.

Thanks!

Paul
