What is the NBN phone?


Still getting your head around the National Broadband Network? Don’t worry, it’s quite complicated. However, once the NBN finally rolls down your street and the time comes to make the switch, your phone service will also come via the NBN, as Australia seeks to phase out the existing copper phone services we use today.

This article will cover all the important details regarding the NBN fibre phone, including:

  • What it is
  • How it works
  • If it’s worth buying
  • How you can get it
  • How much it costs

We’ll also look at what happens if you want to keep your existing phone number and other relevant information.

NBN phone service explained

The NBN is replacing most of the traditional landline networks for phone and internet services The Fibre Phone (the new NBN phone service) has been introduced as a new way to make phone calls as a result. It allows you to make phone calls over your NBN connection. It combines the features of a traditional landline phone service with the cost-effective call charges that your service provider offers.

The NBN has essentially been implemented to phase out the existing copper phone service, and it is more advanced as a result. It comes with all the features that modern consumers expect from a phone, complete with voicemail, call waiting, 3-way chats, caller ID and more, which a lot of modern home phones still don’t have.

The first generation is not an equivalent to a home-phone service. Below are the key differences between the NBN fibre phone and a network phone:

  • The fibre phone can be connected to the NBN connection box, rather than a VoIP modem.
  • It comes with a dedicated bandwidth, meaning calls don’t have to compete with internet traffic.
  • It can only be used at the premises where it was activated using the supplied hardware, which in most cases will be either your home or business. This won’t be an issue for most people however.
  • The NBN phone remains usable for 3 to 11 hours in the event of a power outage. More on this later.

How does the NBN phone work?

You need to have it paired with an active NBN Fibre service as the NBN services are dependent on locally provider power. If your fibre plan is cancelled, your phone service will also be cancelled. It works with your existing handset which saves you money having to pay for a new one.

It has all of the features you can expect from a phone including voicemail, call waiting, 3-way chat, caller ID and more. Moving to the NBN network is not automatic, and as a result you will need to arrange to have your phone and internet services moved to the NBN network before the advised date. Your service provider will be able to advise you on how to do this.

In general terms, the NBN phone service is a Fibre-to-the-home (FTTH) system, where super-fast fibre optic cable carries the signal from your provider to your home. This system is so much faster than the copper wire system because it uses light to transmit data, rather than electric impulses. The copper method is much cheaper to implement, but the NBN FTTH system is significantly faster and requires much less maintenance, so it is the better option in the long-run.

How much does it cost?

Seeing as the phone service is delivered via the NBN, it has the ability to work in a power outage if a battery backup is installed with your NBN phone service (this can be installed at no extra cost when you apply for NBN Fibre with iiNet). If you make a lot of international calls, you can factor this into your NBN Phone package and get cheaper rates. For example iiNet allows you to add an International Call Pack ($10 per month) to your Fibre phone service.

With the NBN phone service, there is an initial $49 setup fee and monthly fees of $29.99, which is very similar to a monthly line rental fee that the average Australian pays today. There are bonuses however, as there is no charge when you call another fibre phone service, you get 18 cent unlimited calls to any standard fixed line in Australia, and rates as good as 5 cents per minute for international calls. Below is table of how much a phone service costs on the NBN according to bit.com.au.

How do I get it?

When the NBN is available in your area, you can firstly order an NBN Broadband service of your choosing. A technician will install an NBN Network Termination Device at your premises. You can keep using your existing phone and broadband while this takes place.

Once the Network Termination Device is up and running, you can order an NBN Fibre Phone service. Fibre phone is available only in NBN Fibre to the premises areas (FTTP)

How do I set it up?

First of all, if you have the NBN FTTB, FTTN, wireless or satellite service, it is impossible for you to get the fibre phone service. If you don’t know what these are, then you don’t have them! Before installing your NBN fibre phone, check that you have each of the following:

  • An active NBN FTTP service
  • An Active fibre phone service
  • A phone handset with a standard RJ11 phone cable

If you have each of these things, then actually installing your NBN fibre phone is as easy as plugging your handset into the UNI-V on the NBN connection box using the phone cable. It’s a little more complicated if you have internal network wiring. If this is the case, then you need to plug one end of the phone cable into the UNI-V port and another into the available phone port on the nearby panel. Below is how iiNet explains.

If this all seems too complicated, or you still aren’t sure what kind of phone service you and cables you have at the moment, then don’t hesitate to contact and NBN installation contractor.

Other things to know

  • You can request that you current number is ported to the Fibre Phone. This will cancel the current phone line and stop your ADSL phone from working. This is why you should do it after your NBN Network Termination Device is up and running. Keeping your current number and service provider can obviously save a lot of stress and effort, so make sure you contact your NBN and service provider to ensure that this is the case.
  • Calls to 19/1900 numbers are not available on the Fibre phone
  • You are responsible for maintaining and replacing your NBN backup battery. Maintaining the battery of your NBN fibre phone is important as they are the only phone service in Australia that can operate during a power outage. During an outage, the battery will provide power for a limited period of time (about 3-11 hours fully charged). This will be less if the battery is not kept charged, and calls to 000 services in the case of an emergency are not guaranteed if you don’t do so.
