^ The ATA could be programmed to ping the VOIPO server, or vise versa.
If the ping fails, a notification sms/email could be sent out.

I could see how this would be a very good thing since I just sat here for the last hour and watched my phone lose connection twice. Though, it was an unusual occurrence...

If you guys are having issues, I would recommend keeping the ATA cool. The #1 reason why electronics turn off is because of heat. If you have your ATA stacked between your cable modem and wireless router you need to move it asap. Some of them look like they can easily be stacked, and could be, but they need adequate ventilation.
