If you mean that the phones simply can't dial and don't actually un-register themselves, it probably because asterisk needs a working DNS server somewhere, and with no Internet, then your DNS server - which looks like your gateway - which I'm guessing is just a dumb forwarder - is failling. I've never undersood quite why asterisk wants to do a DNS lookup for every call, but not been bothered enough to do something about it other than to run a cacheing DNS server on the asterisk box itself just for it's own use.
