I have two asterisk servers one is connected to the PSTN and the other
one is connected to SIP users. The two servers connect with each other
using IAX. When I have an incoming call from PSTN to the asterisk
servers and have a forward to go back out to the PSTN the two IAX
channel bridge together. Now every time I dial a DTMF digit, the
asterisk is sending two DTMF digits. I enable debugging for iax and I
do see it sending the DTMF digits two times. Here is what I see:
The IAX debug that you show below only shows one of each digit. For
each one, it shows Receiving the digit from one leg of the call, and
then transmitting it out the other. I have spaced out your debug to
separate each digit.
Each one shows ...
<----- digit ----
----- ACK ----->
----- digit --->
<---- ACK ------
which is exactly what is supposed to happen.
