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.
