I'm not sure but I think you might want to use Path to resolve this.

When a phone REGISTERs, use
http://www.kamailio.org/docs/modules/stable/modules/path.html#idp3019976
and relay.

On the public kamailio enable path support in the registrar module:
http://www.kamailio.org/docs/modules/stable/modules/registrar.html#idp19423000

You might have to parse headers during INVITE to the natted phones to
figure out the received header with the local adres.
