Anyone got some clues here...  had VFX up and running sweet, but our number was in the wrong calling area.  We got a new number and since then, despite a number of calls with the helpdesk and a couple of hours in a queue waiting, the device wont register / no dial tone.  I've factory reset the device, re entered the profile rule etc, but still all dead.  Bit sad, been without a ph for a couple of days now.

Thanks
