[OpenSIPS-Users] Doubt about provisional responses processing

[Sergio Gutierrez]

Hi Bogdan.

Thanks for your answer.

You may check a trace at http://200.13.254.180/~saguti/fax.cap (Wireshark
format)

if you see, for example frames 6, 10, 13 and 16, have the 200.13.235.178 IP
address at SDP connection, because they are rewritten to be handled by
mediaproxy.
Trouble frame is 26, which is not rewritten at all; SDP connection IP is the
same at both sides. Frame 34 has the same symptom.

Thanks in advance for your help.
