Ok, let's persue this a bit more. How would we want it to work?
(I might be interested in implementing it)

At the IAX level it looks pretty easy, just add an
APPARENT ADDR IE to the REGREJ packet (it is already in REGACK).
The Address would be that of the 'advisory reg server' that should be  
tried next.
The cause code IE could be  "Resource unavailable, unspecified".

How would the asterisk server decide that now was the moment
to send redirects ?
What would the config look like?

Thoughts anyone ?
