FAQs

Do I need to change my phone's handset?
If you only have one phone and it's capable of making voice calls using broadband, you won't need a new phone. It'll work just fine.

Is my phone capable of making voice calls over broadband?
You will need to check your phone's user manual to see if it is capable of making voice calls over broadband. Alternatively, you could search online for your phone's make and model number to see if it is capable.

What if I have multiple handsets?
If you have integrated wiring, you can plug your phones into your wall phone jack.If you don't have integrated wiring you will need to plug your base unit into the back of your One NZ modem. Remember to check that your phone is capable of making voice calls over broadband first.

What is integrated wiring?
When some houses had fibre, or HFC installed, integrated wiring was also added. This means your existing wall phone jacks link to your Fibre or HFC connection. We are unable to offer integrated wiring for our ADSL or VDSL customers, and we recommend talking to your local electrician.

How do I know if I have integrated wiring?
Once your modem is set-up, connected to the internet and you have switched to voice calling over broadband, plug your phone into the wall phone jack. If you hear a dial tone, you have integrated wiring.

Do I have integrated wiring if I'm not on Fibre or HFC?
No, we are unable to offer integrated wiring for our ADSL or VDSL customers at this time. We recommend talking to your local electrician.

Will my phone line work when there's a power cut?
No, during a power cut, your broadband service won't work, so neither will your phone line. This includes all calls, even emergency calls to 111. We recommend you always have a charged back-up mobile phone ready to use in case of an emergency. If you rely on your phone line for contacting 111 emergency services for medical, disability or safety reasons, and have no alternative means for contacting 111, you may qualify for additional support at no extra cost. See here for details.

Do I need to change systems such as monitored alarms?
Most systems such as monitored medical, security or other alarms, fax machines, EFTPOS terminals and loud external ringers should work over broadband. However, we recommend checking with your alarm provider to confirm this.

Will my fax machine work with voice calling over broadband?
Most fax machines will work using voice over broadband. However this depends on the make, model and age of the fax machine. We recommend checking the fax machine’s manual to see if it 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.

Will voice calling work with EFTPOS machine?
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.
