[Asterisk-Users] DTMF detection when outgoing call to mobile phones

[Marc Scheuffler]

Hi all,

I am trying to detect DTMF keys from a mobile when asterisk make an
outgoing call to the mobile.

The DTMF detection on incoming calls (also FROM mobiles) is working very
well.
The only problem is if asterisk called the phone... Nothing is detected.

I am using a digium te205p with PMX/PSTN connection.

Everything that I can find in forums are problems with dtmf detection on
SIP.

Any suggestions?

Cheers 
Marc
