Appreciate everyone's response here! Fortunately we are right in the middle of
setting up a xen box which will hold a few other servers one of which is in fact
a dns server with caching/recursion for local net clients. I'll implement this
with an extended caching time.

/etc/host.conf does have hosts before bind, so I suppose I could also add entries
for the sip providers in the register => lines but I hate to do that incase those
ip's change (however unlikely) it would be a bugger for someone else to chase down.
Checking into the syntax for register in sip.conf its not actually clear if it supports
an ip instead of a fqdn. That would also be easier to track down by someone else if need
be, can this be done? If so although the reg attempt would fail this would alleviate a
dns issue which I assume is the only issue (not failed reg attempts as well).

Once I get back onsite, or can connect remotely I will test this all and post back
for confirmation.

Thanks everyone!
