[asterisk-users] Multiple route failover zaps registration

[Mike Diehl]

Actually, I've configured the phones to use DNS SRV records to find the Asterisk 
server, and this works very well.  The problem is that when the router fails 
over, the phones IP address changes and this causes them to be unavailable 
from Asterisk's point of view.
