Description:Outbound calls placed on the PSTN are fine, but internal calls have one way audio.  Alice calls Bob and can hear him but Bob cannot hear Alice.  Both Alice and Bob are using NAT, although not on the same local area network.


1.4.0 does not have this issue.  It's creeped up only very recently.

As per bug guidelines, you need to attach a SIP debug trace illustrating the problem. Please do the following:
1) Prepare test environment (reduce the amount of unrelated traffic on the server);
2) Make sure your logger.conf has the following line:
  console => notice,warning,error,debug
3) restart Asterisk with the following command:
  'asterisk -Tvvvvvdddddngc | tee /tmp/verbosedebug.txt'
4) Enable SIP transaction logging with the following CLI commands:
set debug 4
set verbose 4
sip debug
5) Trim startup information and attach verbosedebug.txt to the issue.

I just received a bit more accurate description of the reported effects -- apparently "one way audio" is a bit of a misnomer... something is making it to the other end, but it sounds like say... 1  audio frame out of every 100.  Note that it's 100% reproducible.

can you try to collect the information request by serge-v?

yes it's already been attached to the bug

well, looks like two channels are successfully bridged via p2p method. What happens if you add rtp debug to the picture?

There's been a few changes to the RTP bridge lately. Please test with latest 1.4 from subversion. Thanks.
