Yeah, I thought about that too, which is why I set up tools to monitor
packet loss and measure jitter.  It uses a non-conflicting UDP port
near the one that IAX2 uses.  My tests indicate very little loss and
the same jitter in both directions.

What I really want is a way to get asterisk to yelp if it notices that
its about to make the call sound bad due to late/missing packets or
for whatever reason.  Right now it seems that the network is
functioning normally but still one direction of the calls sounds
intermittently awful.
