Hello Alex,

I cleaned location table and create domain in db and getting error like

Hello Alex,

Restart both clients and tried call and call is looping to same extension.

Slava.

Hello Alex,

Yes, rtpproxy should handle nat cases, but i think on directly connected network should be able handle without any nat.

Well, that's progress!

Kamailio is not involved in RTP, however[1].

Could it be that there is a network or transport-layer reachability
issue between your endpoints? Or a firewall getting in the way, perhaps?

[1] It can control third-party, outboard RTP relays such as 'rtpproxy',
though. But those are separate processes and pieces of software.
