Maybe it's possible to send a NOTIFY to a peer on the last IP it was 
seen at?  I don't think I've seen anything that has a "register" 
command, but lots of devices can get a "check your config" or "reboot" 
command via SIP NOTIFY.

....I'm more wondering why the peer is unregistered but we still expect 
to communicate with it.  Other than a network problem or the device 
being unplugged...neither of which could be fixed from the server.
