Hello everyone,

I'm experiencing the problem described in subject.
My UAC is Vega Europa 50 with t38 enabled, and it sends different port numbers for audio in initial request and for image in t38 reinvite, but when my script calls force_rtp_proxy(), rtpproxy replies with same port numbers for both requests. My script routes requests to Asterisk box, and when my Vega Europa starts t38 rtp, Asterisk doesn't treat this traffic as a valid udptl.

Here is a dialog between Vega and Kamailio http://pastebin.com/raw.php?i=K5mGdCpU
Here is a snippet from kamailio log http://pastebin.com/raw.php?i=qvemH76J
I don't think is wrong keeping the same ports in the re-INVITE that is switching to t38 -- rtpproxy is reusing the ports allocated for the session (upon matching callid and tags). Do you get any logs in asterisk indicating why is not considering the rtp traffic anymore?

Cheers,
Daniel

I would appreciate any help,
Fedor.
