hi all, thanks for your answer. but i think this is a problem when configure nathelper. because when we use rtpproxy, we must divide some case as different NAT and same NAT.

thanks again.

please help me to configure that : if sip client is in the same NAT(same LAN network) , they can make call directly (RTP go direct without through RTP proxy). thanks so much

Truong, nobody will do your work for you by free. This is a users maillist not a free consultance service.

As a side note, I confirm you that what you what to achieve is feasible (I've it working in some deployments).

Regards.

Which problem do you mean? It's as easy as matching two IP's.

And why do you expect that force_rtp_proxy() would do nothing in case both endpoints are in the same LAN? where in the nathelper module documentation is writen that?? This is not an "out-of-the-box" feature so please don't complain if it "doesn't work" as just you expect.

If you want RtpProxy not to being invoked for calls within the same NAT, then you should code a specific logic in kamailio.cfg in order to avoid calling force_rtp_proxy() when caller and called are detected to be in same NAT.

This is the maximun I can help you on this thread as you have provided nothing (no tests, no attempts, no code) but just a wrong assumption about RtpProxy behavior. If you want a working code you should do it by yourself or pay a consultant to get it working.

Regards.
