Hello Ovidiu and Bogdan,

Thanks a lot for both of your answers. I should have be more carefull
with that issue, as I'm afraid I should have solved this myself,
especially because it has already been specifically addressed both here
and in the v1.1 nathelper module.

The thing is I did read about the "c" option in force_rtp_proxy
documentation, I just got confused by session/media description in SDP.
Now that I've just read the RFC2327 (which I already went through, but
not carefully enough), everything is clear as crystal :-)

So, if I have a message for people like me reading this : RTFR(FCs) !!!
(this is sooo much compatible with the Fu****g word than the plain old
RTFM.).

Now that I've read it, I'm gonna be bitchy about it : ain't the session
description delimited by "v=" and not "s=", according to RFC2327 ? ;-p

Thanks again,
I was really amazed by such a fast answer (first time I post here).

Best Regards,
