Snip---

Ok, I am confused. Are you saying that if I use an IAX2 inter machine
trunk from one asterisk box to another, and terminate a call over the
pstn to a voicemail system or other type of IVR, IAX2 will regenerate
the DTMF tones that were originated  from the original callers phone? I
thought the original posting said that the IAXy device was failing to
pass DTMF through to the termination side of the call.  What have I
missed?
