asterisk users - May 2006 - AW: DTMF detection when outgoing call to mobilephones

Yes I can hear the DTMF keys. I ve tried 2 different phones and 3 different
mobile network providers. Nothing.

I played with the rx/txgain values from hearing nothing to too loud... 
I have no more ideas.

Can you hear DTMF tones from the cellphone when you call it? It is possible they
are not produced. I'm not sure if that is a handset or network issue, but I
had this happen a few years ago when implementing an IVR that called subscribers
for notification, and expected input from them. Most of the time it worked, but
some phones in some locations sent nothing. If the phone made a call from the
same location there was no problem.

>From my recent problem on this sort of thing, I'd suggest you set the
timeout to around 1500ms in the feature.conf file. This is of course if your
using the DTMF digit's to activate any of the features.

also make the devices both sides of the call are using the same DTMF mode.

There was a bug in various versions of Asterisk when outbound calls were
placed using spool files and then could not detect DTMF from the called
party. Without more details, including the version of Asterisk you are
running, it will be difficult to suggest anything to you other than
upgrading to the latest release.

Works perfectly on mine. Using Digium Digital boards (ZAP -> UK Mobile).
Asterisk version 1.2.1 with a few patches.

Also works for me with USA cell phones on at least two different 
Asterisk servers with version 1.2.x
