hi,
my diagram is : sip client <--> nat <--> kamailio server <--> nat <--> sip client (something like that).
you said that i can use "RTP tunnel solution"(as RtpProxy ?).
I hope that kamailio handle signaling protocol and media stream go direct from sip client to another .
thanks for help.

STUN / ICE in both endpoints. If not, you need a RTP tunnel solution
(as RtpProxy). Magic doesn't exist.
