[Asterisk-Users] Teliax IAX problems -- Asterisk doesn't see answer

[Rich Adamson]

I've been trying to diagnose the same problem with teliax, and it seems
to be a jitterbuffer problem. Since turning it off, we've not had a problem.

My guess is that teliax servers are not current code, or they've modified
the code for some reason.

The tech that I corresponded with suggested 'gsm' was the culprit, but I
had the same issues with g729, ilbc, etc.

Try jitterbuffer=no in the appropriate section of your iax.conf and restart
asterisk.
