What is PSTN Failover?

"PSTN Failover" is a way of plugging in your modem and handset so it can make and receive both Home Phone (landline) and VoIP (Voice over Internet Protocol) calls.

  • By default, outgoing calls will be made using your Netphone (VoIP) service.
  • In the event that your broadband or VoIP service is down, outgoing calls will be made using your Home Phone service - if this is the case, before you dial a number you'll hear an alert through the handset speaker that Home Phone rates will apply to the call.
  • You can force a call to be made using your Home Phone service instead of the VoIP service by dialling ** before the phone number.

To set up, all you need to do is to make sure the PHONE side of your line filter/splitter is connected to the special PSTN failover port on your modem. Please see the specific instructions we've prepared for our modems below.
