Use tcpdump or Ethereal to see what happenes is always a good idea.

Hi Maxim,
UA1 is the Nortel Networks SIP Client. I did not put it behind a NAT so
as
to avoid any issues. But I followed your suggestion
and swapped it for
another ATA186. It seems to work fine now. Made about 20 calls and all
had
fine audio. Any ideas why other UAs can have problems
even though they
are
not behind a NAT??
>From my observations of the rtpproxy output, I notice that when the call
is
successfull I see these two lines:
addr1 filled in
addr2 filled in
But when there is no audio I only see:
addr1 filled in
By the way we mainly use ATA186s on our network but there are a handul of
others that should coexist if we were to deply the RTPProxy.
Thanks,
Ricardo
