Hi all,
I've got this ongoing problem currently being looked at by James Beck in AA 
Support. Phone suddenly stopped working. Configuration has been unchanged 
since support remotely upgraded the firmware last year. Phone is a snom300

Phone says it is unregistered

There is no dial tone

Incoming calls go straight to voicemail

Outgoing calls *can* be made.

Phone is on a DMZ

Router is a Netgear DG834PN



Anyone got a clue as to what's going on here?
