This is the standard Kamailio behavior. Thus, you should apply NAT 
traversal techniques to instruct Kamailio to reuse the established 
connection.

In short: for each register call fix_nated_register(). For every other 
request and response call fix_nated_contact().

Thus, if you use the default configuration and apply NAT traversal it 
should work.
