Do DTMFs work on a simple call to Asterisk? A simple IVR or VoiceMail.

Can you recerd the audio before it gets to Asterisk? use:

  dahdi_monitor 1 -r rec.raw; sox -r 8000 -c 1 -s -w rec.wav

Can you hear the DTMFs in rec.wav?

Another thing to try: press a key for a few seconds. Do you hear it
continously?
