This article will teach you how to set up PSTN failover on compatible modems purchased from the iiNet Group.

Please note that the following VoIP-enabled modems supplied by iiNet do not support PSTN Failover: TG-789 Broadband Gateway, Cable Gateway Pro, NetComm NB16WV-02, VDSL Home Gateway (Huawei HG658), Huawei HG659.

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

Our Budii and BoB range of modems have the smarts to recognise both your Home Phone and Netphone numbers, so it can route incoming calls for either number to the phone handset that's connected to your modem.

You can also make outgoing calls using either your Netphone or Home Phone service - see Using your Phone with PSTN Failover for more details.

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.

  1. If you haven’t already done so, make sure your modem is plugged into the ADSL port of a line filter, and the line filter is plugged into your telephony wall socket.

  4. Once your VoIP service is set up, you’ll need to plug a standard phone handset into the green Phone port on the back of the modem.

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. This default warning can be disabled in the modem settings of a Budii/BoB range modem, but we don't recommend it.

You can force a call to be made using your Home Phone service instead of the VoIP service by dialling ** before the phone number.
