Hi,
Your client must support symmetric RTP for rtpproxy to work. It must
send and receive media on the same port - that's the only way to make
media to cross the NAT; check if you can configure your client to do so.

Anyone that knows which clients support symmetric RTP?
Cisco, Mitel, Grandstream, Windows Messenger, X-Lite, Snom, kphone,
ATA.
The vast majority of clients available today support symmetric RTP.
