well, if after the NATed UA receives the 200 OK it has to start sending RTP and it is symetric(sends and receive data throught the same port), then there is no need of a media proxy, since the called part knows from which port in the NAT box the NATed UA is using... I am getting confused about why I need to use a media proxy....

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.
