Hi Maxim,

I have tested on 0.8.12dev-t10 installed on RedHat 7.3.

The results are mixed.  Only about 40% of the calls have audio even though
the SDP is rewritten properly.

My test setup is like this:

UA1( --

I have included the "-f" output from the rtpproxy plus 4 ngrep files.

1.  success_from_internet.txt --> good call from UA1 to ATA186
2.  fail_from_internet.txt ---> no audio call from UA1 to ATA186
3.  success_from_nat.txt ----> good call from ATA186 to UA1
4.  fail_from_nat.txt  ---> no audio call from ATA186 to UA1

Please let me know how else we can troubleshoot this.
