This is usually a NAT related issue on the ATA side. You see, if your ATA is behind a firewall and registers with Voxalot a certain port is opened by your firewall.
Now depending on how long your device takes between registrations, sometimes your firewall will close this port and subsequently, when an inbound call comes in, Voxalot tries to send the call to this port.
If this is occurring, you need to look at things like Registration expiration, STUN, NAT keep alives and at the extreme case port forwarding options.
Alot of people immediately point the finger at Voxalot, however as I pointed out it is usually a problem on the ATA side.
