In the source tree, there are some examples on how to engage rtpproxy (using nathelper module): see "modules/nathelper/examples/alg.cfg". You need to run opensips in proxy mode (this is the server that will control the rtpproxy) on one server and on a separate server you need to tun opensips in b2b mode. You need to separate servers. Hope this heps.
