It still sounds like it might be a user-side problem. This same scenario happens for instance when your WAN side IP address changes prior to the registration expiry. Since your registration lasts 60 minutes, that means if your IP address tends to change more often than that, your incoming calls will all be in limbo, and go to VM or silence or cause a busy signal. I am not sure why your other provider would work while Voxalot didn't though, if you have the exact same settings across the board for both lines.
Try changing the expiration of the registration to 300 or 600 and see if that helps you.
