uhm..... I didn't know that. That is a very good explanation. If it
has to start sending RTP, then the media proxy now knows what port it
is using in tha NAT box. I thought that after the 200 OK, the nated UA
would wait for audio to come, since it sent all the parameters in the
SDP body.

Thanks for the explanation.
