Re: [asterisk-users] Asterisk dies when external access is lost
just an idea, could it have something to do with DNS being unavailable, but that wouldn't really explain why it would die when ADSL is down... h.

Doug, No, the phones are all Snom phones - a mix of 290s (actually elmeg IP190), 320s and 360s. Mostly using firmware v6.

Turned out that our bind install wouldn't respond to the network that the phones were on (10.10.10.x). Since then, I've found how to make bind respond that that network segment as well and the phones are fine.
