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:
