[SR-Users] Kamailio proxy for far-end nat traversal

[Daniel-Constantin Mierla]

Hello,

you can force rtp relaying always, if it is what you want -- just call
rtpproxy_manage() for all INVITE requests and their replies.

Otherwise you have to tune the nat_uac_test() parameter in order to
match what you want to relay.

For signaling relaying, be sure you do record_route() for calls.

Cheers,
Daniel
