[asterisk-users] Losing local SIP phones when internet goes down?

Hi all,

Many thanks for all your very fast and really helpful replies!

Now I know about the asynchronous DNS issue, this all starts to make 
sense: presumably, when I disabled eth1 completely, the DNS queries just 
failed immediately, so didn't hold anything else up, whereas in the other 
scenarios (router or phone line down) the DNS requests weren't being 
answered, so Asterisk was waiting, preventing it from doing other things 
properly.

So, as suggested, I'll go ahead and install dnsmasq (or similar), and that 
should fix things.

Cheers,

Nikhil.
