Thanks. I stand corrected. I probably should have said that in-between registrations it was losing the "ability" to communicate with SIP server even though the lines showed registered. There's no doubt that I was seeing sporadic loss of registrations on his lines in vPanel up until Monday. His problems were identical to what others have posted.

The failover problem this morning was symptomatic of the same registration/connectivity problems that have been affecting most of the BYOD folks over the past week. I just assumed it was the same ongoing issue. His ATA is in the DMZ of the router, so I doubt it was a response or firewall issue with his device.

Is this case considered closed? I'm assuming all the support tickets have been cleared up.
