Just to quote and save everybody the searching:

   Once a client has established bindings at a registrar, it MAY send
   subsequent registrations containing new bindings or modifications to
   existing bindings as necessary.  The 2xx response to the REGISTER
   request will contain, in a Contact header field, a complete list of
   bindings that have been registered for this address-of-record at this
   registrar.
