Hello, can you get the traffic on load balancer (or the first hop in your network that received the invite)? There you can see if the fault is in your network or not.
In kamailio.cfg, be sure you don't use fix_nated_contact() function unless you are the first hop receiving the sip message (request or reply). As a matter of fact, fix_nated_contact() should not be used anymore, use set_contact_alias() instead and handle requests within dialog with handle_ruri_alias() -- see default kamailio.cfg for latest kamailio versions.
