That's not what you want to do, and it would not result in working
behaviour. The Contact URIs need to be of the respective user agents for
in-dialog requests to be routed correctly.

What you really need are the server-side NAT traversal folk traditions
of the nathelper module. Examples of its use abound, including in the
stock Kamailio config.
