asterisk users - Jun 2005 - Asterisk does not function without a DNS server

Hi all,

We have our Asterisk server running smoothly with a SIP BRI gateway
for inbound calls. However if the Internet connection goes down and a
DNS server becomes unreachable Asterisk basically does not function.
By this I mean it does not answer call coming in from the gateway
(which is on the local LAN) and you can't even reload it - just hangs
there. If I change the DNS setting in resolv.conf to something else
which is reachable all is well again.

I have tried setting srvlookup=no in sip.conf but it made no difference.

Does anyone know how I to make Asterisk continue working for local LAN
users/gateways when a DNS server is not reachable?

How about running a DNS caching server on the same machine as
Asterisk?
