Thanks for your reply...

I don't understand exactly "lso note that first you need incoming RTP
(from client to RTPproxy) in order to be able to send RTP behind the nat." ...

Checking the traffic with ethereal in the server (rtproxy and openser are running on the same machine for the moment), I can see that bothe clients are sending packets, but then when rtpproxy routes them to the onthr client, I see "ICMP unreacheable host" for both sides.....

I will check the client more carefully to be sure it is synmetric...

Thanks again!!!!

Hi Amanda,

be sure the devices are symmetric from RTP point of view - otherwise the
traversal will not work. Also note that first you need incoming RTP
(from client to RTPproxy) in order to be able to send RTP behind the nat.
