Business phone systems

Spend less, get more

Whether you’re setting up a new business or replacing an aging PABX, a VOIP phone system from GTB brings you…

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, adding them in or change their 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, from having the phones answered by a friendly voice and giving options to call flows and how long phones ring for to 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.

Proven, secure, reliable

Maybe you’ve heard that VoIP is not very good? Well, that is no longer the case. VoIP technology has come of age. The calls are high quality, and the service is very reliable. Because of this, our VoIP system has been the solution to many companies phone needs.

Asset utilisation

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

Ease of use and features

See when you have messages for you, easily manage your mailbox, email voicemail messages for action. Benefits from other features such as the ability to ring multiple phones simultaneously, reducing your callers wait until their call is answered.


Take your office extension with you on your smartphone with our softphone app and service.

NZ Toll-Free, 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 to have 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.

GTB recently carried out a complete change in phone system for us over to VOIP as well as new PC's. Their communication was excellent & their advice & recommendations were clear and easy to understand. We were happy with their pricing too. Highly recommend GTB.
