I hate to pile up on you guys, but I have been having the same issues and I am assuming it is the same problem. Last night between 6 and 7 pm I received 2 calls on my failover number, so I am assuming the ata had become unregistered. Shortly after 7:15 or so, it started working again. I opened a ticket on this. Now, this afternoon, another call went to my failover, in fact it was from another Voipo number and shortly thereafter it was working again. I have rebooted that AATA 2 or 3 times since yesterday thinking there was some sort of config push I hadn't gotten, but this seems to be an on-going issue. Thankfully, my failover seems to be working fine so I can deal with it, but I'm hoping someone gets a handle on this soon. So far I have turned several people onto Voipo and they have signed up, but I don't dare do this now until this problem gets solved for good. I know you guys are trying hard to get to the bottom of it, so I wait patiently, knowing that you will indeed solve this soon.
