So that brings me back to the original question. Can I ask the registrar to
register say for a month providing it a SIP URL as a contact? On one hand
the Bis limits it (i.e. what a client is allowed to request), on the other
hand the forking example (15.5) implies that one may have a 'permanent'
registration ?!
