Section 8.1.1.1 RFC 3261

   The initial Request-URI of the message SHOULD be set to the value of
   the URI in the To field.  One notable exception is the REGISTER
   method; behavior for setting the Request-URI of REGISTER is given in
   Section 10.  It may also be undesirable for privacy reasons or
   convenience to set these fields to the same value (especially if the
   originating UA expects that the Request-URI will be changed during
   transit).

I guess it won't be a big deal to always use the AOR in the To field, 
especially since we expect the Request-URI to be changed during transit.
