Summary:                    Failing registrations to peer via DNS name breaks
all other peers
Description: 
A peer we register some DID's from via a DNS hostname for the peer went
down today.  The DNS hostname was not resolvable either.  This failing
registration caused all the end user SIP phones registered to the server to
unregister.

Tried restarting, but the phones did not register.  After commenting the
'register => xxxx:xxxx at failed-peer-name.com/xxxx' lines and restarting the
phones registered.

Console during issue:
