Hi,

is there a way to enable dtmf detection on zap channels? I am trying to
pickup, play a ringtone and the dial out. I.e.
 
exten => s,1,Wait,1                     
exten => s,1,Answer                     
exten => s,2,Playtones(dial)
exten => s,3,DigitTimeout,5             
exten => s,4,ResponseTimeout,10
exten => _X,1,StopPlaytones
exten => _X,2,Dial,Zap/g8/BYEXTENSION|10

I don't quite recall what I did last, but I remember this used to work.
My current installation of asterisk does not detect dtmf tones as I can
easily verify with debugging turned on. Just to be sure I also dialed in
from different phones, did a fresh checkout of zaptel, libpri and
asterisk and wrote my configuration from scratch. None of that made
asterisk detect dtmf, though.

Can anybody suggest what to try next?

Yo Thilo,

I encountered the same problem, and first solved it by using
"BackGround" to play a recording of a dial-tone, as
"Playtones"
doesn't do anything with any digits dialled while a tone is beeing played.

A while ago, I made some modifications to "Playtones" to allow it to
be
interrupted by dialling a digit and behave very much like "BackGround"
in that respect.  The patch to add this new app, called
"PlayDialtone", is
attached.
