My bad: "cwii" - sounds ok, but WAN Kamailio in RTP debug "from/to".

rtpproxy_manage("cwie"); - good for Echo() test,
when UA behind NAT, registered on Kamailip and calling Asterisk Echo() test exten - voice perfect.
RTP - from/to only Kamailio LAN IP (2.2.2.2) - what is my goal.

But need to know, where I must put another flags for UA-t-UA calling, when both behind teh NAT and registered with Kamailio?

Because I have WAN2LAN in RTP and both are IPs of Kamailio:
