[Asterisk-Users] dialing into * then forwarded out gets choppy audio

Hello all!

If I place a call to our number, the call is routed to our Asterisk box
from teliax --> IAX2 --> firewall w/ port forwarding --> *

If that caller dials an extension that rings an outside line, where our *
box makes an outbound connection to teliax to terminate the call, we get
choppy audio. Internal extensions have been dialing outbound calls no
problem for over a week.

What could be causing this? IAX2 debug is not showing any errors.

To be more specific about the audio:
The originating caller can hear the called user fine.
The called user may only intermittently hear the caller, and usually only
if the caller talks extremely loud or close to the mic.

I've tested this in the middle of the night with no other network traffic
happening. Even then we've got a fat pipe with IAX2 ports QoSd at top
priority. We're only 3 hops (~30 ms) from teliax.

Any ideas are appreciated...

Sorry for the bump... catching flak for this though, if someone can help
it's much appreciated.

Best regards,
