Cost-effective phone solutions for Wellington-based business. 
Whether you're setting up a new business or replacing an aging PABX system, a VoIP (Voice Over IP) phone system from GTB brings you savings, quality & flexibility.

Why GTB Phones?

Massive cost savings

Cost far less to set up and gives massively lower monthly costs than old-style traditional PABX.  As these phones run through the Internet, it means you no longer need to pay line maintenance on your telephone bill. In plain English, VoIP is a lot cheaper than a standard phone system.
Your upfront setup costs will be paid back quickly from your ongoing savings, and from there, it's just saving for you.

Better sound quality

Clients consistently report that their new VOIP phones provide much clearer sound on the handset, headset and speakerphone.


Make it easy and quick to move staff around, add them in or change offices – and we can easily do it for you if you prefer.


Connect you and your team wherever you are. Wherever you are in the world, you can get your dial tone if you can access the Internet. Simply take your headset or IP phone.
So if you have to work from home, you can take phones with you, or even have extra phones permanently at home. Important for your business continuity.

Custom made

We work with you to customise the setup to your business needs. 

  • Having the phones answered by a friendly voice giving options.

  • Custom call flows.

  • How long do the phones ring for before going to voicemail?

  • Auto-forwarding options.

Changes further down the line are easy to make as well. You can have a quick call or an email to us, and you can have options changed, redirects set up, or even a whole new user ready to go.
Pick the phone to best suit the person. From cost-effective business-grade desktop phones, reception or power user models with more functions, walk around DECT or wifi phones, and headsets.

Use your internet connection rather than needing a separate phone network.

Ease of use and features

Softphones on different devices.


Take your office extension with you on your smartphone with our softphone app and service. Softphones are great for working from home and taking calls while away from the office.

New Zealand Toll-Free (0800 & 0508) - Regional and International Numbers

We can supply them all and add them to your phone system at very competitive rates - saving you ongoing money.
For example - We have a legal firm client with three physical locations in two different free calling areas. They have a local free calling number in both areas, all answered by the receptionist in one of the offices and then internally transferred as needed. People prefer a local number to call.
For example - we have an online business client located here and selling in NZ and Australia. They have toll-free Australian numbers that ring in their NZ commercial and home offices simultaneously, identifying the call as from Australia so they can answer correctly.

What is VoIP?

Voice over Internet Protocol (VoIP) is a type of telephone service that allows users to place and receive phone calls using a broadband Internet connection instead of a regular (or analog) phone line.

If you've heard of an IP address, that's your Internet Protocol address. An IP address is how computers and devices communicate with each other on the internet. 

VoIP technology has been around for longer than most people realize. Telephony has relied on digital lines to carry phone calls since the late 1990s, but the term VoIP wasn't coined until 1995. VoIP is a cost-effective way to handle an unlimited number of calls by using a high-speed Internet connection instead of a traditional phone line.

VoIP uses your existing internet connection.

If you have a broadband internet connection, you can call anyone in the world without the need for a local phone service. VoIP solutions work on any computer or mobile device because they're built upon many years of open standards.
