Perhaps we need to go over this again.
IAX2 CANNOT DO INBAND DTMF. IAX2 DOES NOT USE RTP. IAX2 DOES NOT DO
RFC2833.

Before to anything else, are you sending DTMF in-ound or out-bound?
Most of the time when DTMF is not sent is because is in-bound. Just choose
out-bound or RFC2833 (I don't remember if this is the right standard).

Subject: [Asterisk-Users] DTMF not sending properly via IAX
I'm not sure if this is a -users or a -dev question, since the answer
probably comes down to something in the code.
I'm running the latest CVS-STABLE, and am subscribed to PSTN service
using IAX2 via Voiptalk in the UK.
I've just been alerted by a customer that the sending of DTMF from my
asterisk box to a remote PSTN user doesn't work, although it used to.
To test it, I have the following dialplan entries, that I can dial into:
exten => s,1,Answer
exten => s,2,Wait(2)
exten => s,3,SendDTMF(1234567890)
exten => s,4,Wait(2)
exten => s,5,Hangup
What happens is that whatever string I give to SendDTMF, I only hear the
first DTMF digit. The remaining digits don't get sent.
I recently updated from an April CVS-STABLE to the July 4 version, but I
couldn't see any relevant differences in the code. As its a production
system, I can't just revert to test without planning.
I don't know whether Voiptalk have changed anything.
Is this a known bug in certain versions of Asterisk?
If I do iax2 debug, I *can* see DTMF frames being sent and acked for
each digit. Wo I can't understand why I'm not hearing all the digits.
Any ideas?
Cheers
Tony
