Want to use voice calling over broadband?

Voice calling over broadband – or Voice over Internet Protocol (VoIP) – lets you use your landline phone to make calls over high-speed broadband.

Check if you're ready to upgrade

Happy to plug your phone into the modem supplied?

If this doesn’t work for you, we suggest you buy a cordless DECT phone (Digitally Enhanced Cordless Telephone) from your local electronics store. This allows you to place the base station next to your modem and the other handset provided in a location that suits you.

Wall Ports
Want to continue to use your existing wall ports?

You’ll need to contact us if you want to continue using your wall ports instead of plugging your IP capable phone into the modem. If you have fibre installed, we’re able to offer you an integrated wiring solution, at a nominal fee. Please note, this service is not available for VDSL.

Use Voicemail
Do you use voicemail?

Save any messages you want to keep before you change to voice calling over broadband. A simple way to do this is use the voice recorder app on your mobile phone. Just press play on your voicemail message you want saved and at the same time, press ‘record’ on your mobile phone recorder app.

Fax Machine
Do you have a fax machine?

Most fax machines will work using voice over broadband. However this depends on the make, model and age of the fax machine used. We recommend checking to see if your fax machine will work over broadband. You may also want to consider using a cloud based fax solution e.g. fax to email services instead of your fax machine. Providers such as TNZ offer this alternative.

Monitored Alarm
Do you use a monitored medical, security, freezer or HVAC alarm?

Most systems such as monitored medical, security or other alarms should work over broadband. However, we recommend you have a discussion with your alarm provider to confirm this. If your existing alarm is incompatible, they should be able to help you find an alternative solution

External Ringer
Do you use a loud external ringer?

If so, you’ll need to check with your provider to ensure it‘s set up to work with your new voice calling over broadband solution. If your existing ringer is incompatible, they should be able to help find an alternative solution.

EFTPOS Machine
Do you have EFTPOS?

The majority of EFTPOS terminals should work over broadband rather than using a dial up phone line. However, we recommend you have a discussion with your EFTPOS terminal provider to confirm this before you upgrade.

Emergency Phone
Do you have a lift emergency phone that you’re billed for?

We recommend you contact your lift service provider to ensure your lift emergency phone will work when you upgrade to broadband. If your existing lift emergency phone is incompatible, they should be able to offer you an alternative solution.


Do I need to change my landline phone?

If you only have one phone and it’s VoIP capable, you won’t need a new phone. It’ll work just fine. If you’re not sure, check your phone’s user manual.

If you don’t have integrated wiring and you have multiple phones where each one plugs into a separate phone jack in the wall then you’ll need to replace them with a new VoIP capable base unit with multiple handsets.
What is integrated wiring and how do I know if I have it?

When some houses had fibre and UltraFast HFC installed, integrated wiring was also added. This means that each of your phone jacks link up to your fibre connection. If you’re not sure if you have integrated wiring, simply plug your home phones into the phone jacks after you’ve moved to voice calling over broadband, and if there’s a dial tone that means you have integrated wiring.  

We are unable to offer integrated wiring for our ADSL or VDSL customers, we recommend talking to your local electrician.
Will my landline phone work when there’s a power cut?

All voice calling over broadband calls are made using your broadband connection. During a power cut, your broadband doesn’t work, so neither will your home phone. This includes all calls, even emergency calls to 111. We recommend always having a charged mobile phone ready to use as a backup.
What call features are available?

The following call features are all available with voice calling over broadband: Voicemail, Phone Divert, BestMates for home phone, Caller ID, Call Control and Call Waiting.

You may need to set them up again once your VoIP services are activated – you’ll find the guides on how to use the features here. Or if you’d like to add any of these services, contact us on the details below.
