[Asterisk-Users] IAX DTMF Problem...

[Mark Edwards]

Thanks guys - appreciate the comments. I understand that IAX does not 
support inband dtmf, but I still can't fathom why 9 times out of 10 my * box 
is ignoring DTMF's even though they are showing up in the IAX2 protocol 
debug output. The really annoying thing is that I can't consistently 
reproduce the issue - every now and again it just works. I have logged a bug 
004631 and will see what happens from here.
 cheers,
 Mark
