[Serdev] two session on rtpproxy with video?

[Rodrigo Frez]

if video are present and we want to pass through the rtpproxy, this means
that we have two open sessions?. If so, maybe the sdp flag inserted when
executing force_rtp_proxy, does not let the video pass through the proxy.
I use ethereal to see what happen to video packets and sip related messages,
and yes, the sdp headers are changed, and the IP is rewrited, but when the
udp packets of video begin to come from a client, ethereal show me a destination
unreacheable message, due to the port on the server...

So:

    Client->NAT->SER&RTPPROXY
                           *

the video packets in (*) have by destiny somo port on the server that is
not ready to listen, and I think is to due that the rtpproxy is not listening,
because never open a session to handle the video...

PS: I hope I explaine it well...
