I'm running named as a caching nameserver. /etc/resolv.conf point to 
localhost. But, obviously, it only responds from the cache, since the 
root servers are unavailable.

tcpdump is an interesting idea. The only trouble is that I'm not sure 
when to run it. The phones don't go dead immediately. And not sure what 
to sort on if I do run it.

Still puzzled about why asterisk does an address lookup, and why it 
unregisters sip phones with a hard ip address if it fails.
