Sorry, I missed that. Well, as long as what we wanted to test is tested....

I did this. I waited as long as 2 seconds. Still the same problem
unfortunately. I can see the DTMF in the IAX trace. The AGI trace just
sits there...

I have a few other things to try, but that is more like a work-around or
at least a different way to attack the problem. Richard Lyman gave me
this link http://dynx.net/ASTERISK/gnudialer/agiIVR.agi and I will look
into that as well.

Generally I have had quite some issues since upgrading to 1.4 (IVR DTMF
fails to be detected sometimes on incoming calls, with SIP => IAX
providers I get dropped incoming audio). I am attacking one problem at a
time though.
