I would like to know how to do this as well, but for different reasons: 
mobile users.  If I'm in the office my SIP phone registers with the local * 
box, or at my house wiht my * box, and so on and so forth, so my extension 
moves with me.  If I'm not anywhere near a * box the SIP registration 
eventually dies and since there's no SIP registration it calls my cell 
phone...  kind of like a universal extension type of thing.

I know I can dial all of them with one extension and whichever picks up 
picks up but that seems a little ... hokey.  I can't think of a better way 
to do it short of being able to propagate registrations across * boxes.
