Thank you, Klaus for your prompt reply.

Now Kamailio listens on local IP (192.168.1.137)
I've added advertised_address line into my conf (I've added here my public hostname)
Also I have configured RTPProxy on port 22222, and now Kamailio starts without errors or
warnings:
Apr 7 04:58:37 sipbox kamailio[2465]: INFO: rtpproxy [rtpproxy.c:1403]: rtp proxy <udp:127.0.0.1:22222> found, support for it enabled

But still the problem persists. I am not able to register with kamailio via public IP.

DMZ is turned on, so I guess router should forward all ports to .137 address.

When trying to register, I am getting request timed out.

Any ideas ?

Thanks

Kamailio can only listen to local IP addresses. The public IP address is
not on your server, but on the public interface of the NAT Router. I
guess the NAT router just does a forwarding to 192.168.1.137.

Having a SIP proxy behind NAT will give you lot of headache. Anyway,
listen only to the local IP address (192.168.1.137) and try
advertised_address:
