In fact, in case of PATH usage, the registrar should receive the request for a 
registered user, add Route header pointing to the inbound/outbound proxy of 
the registered user and change the RURI with the real location of the 
registered user (or mapped public address in case of NAT), route the request 
to it, and the inbound/outbound proxy should remove the Route header and route 
the request based on the RURI as usual.
