This one is good or the new 2.0 version also supports the -A flag. You
may want to run in debug or info mode to see if you're passing packets.

Something like:

rtpproxy -A PUBLICIP -F -l PRIVATEIP -m 10000 -M 20000 -s
udp:127.0.0.1:7722 -d INFO

Making sure that the m (minimum) and M (maximum) ports match what you
have opened/forwarded on your firewall.

The address should be your public ip (for outside connections), which
should also be in the advertised statement within kamailio.
