VoIP: the state of play in New Zealand

Voice Over IP (VoIP) is probably not yet the most used way for people to call each other in New Zealand. But it will be - sooner rather than later.

I am often asked a number of questions about VoIP. What are the rates of adoption? Is the voice quality OK? Do you provide VoIP lines? Who else does?

This prompted me to put together this overview on the state of play of VoIP in New Zealand. The way I see it. No statistics or scientific method here - this is simply a report from the trenches.

Looking at the industry I split the telecommunication companies into three tiers. Telecom, TelstraClear and Vodafone are what I call first-tier telecommunication companies. The second-tier telecommunication companies are local internet service providers, now delivering phone services, such as CallPlus, Orcon, WorldXchange and Snap Internet. There are also many third-tier, smaller providers like 2Talk, Kiwi and others in the market today.

At Home

First, I will distinguish between the residential and business phone lines. The Plain, Old Telephone Service line (POTS line) is the type of line most people still use at home. Until recently this was the only option.

In the last few years some ISPs and third-tier telecommunication companies started offering a service where you could buy an IP phone and get a phone number from them. As this was not widely publicized and the set-up was quite technical, this service was only used by a few enthusiasts that knew what they were doing.


Now, with the arrival of Orcon's Genius product this home scene may change.


At Work

Now, to the business world.

Most businesses don't simply just rent a phone line. They normally use a phone system to connect to telecommunications companies phone lines and have company telephones connect to the telephone system.

VoIP is a method that can be used by the telephone to communicate with the telephone system, as well as the method that can be used by the telephone system to connect to the telecommunications network.

People often confuse the two. Lets split the two up. I will call the method of connecting telephones to the telephone system via VoIP as IP telephony; I will call the method of connecting telephone system to the telecommunications network via VoIP as VoIP phone lines.

When we talk about rates of adoption it is important to look at the two separately. IP Telephony has been steadily adopted in the enterprise since late 90's - early 2000's, while first VoIP phone lines only became available in New Zealand around 2005.

As such, the rate of adoption of IP telephony is much higher than the rate of adoption of VoIP phone lines. From my personal observations, both have now entered the mainstream business. While at home we still use POTS, at work both IP telephony and VoIP phone lines well passed the early adoption stage.

Despite this being the case, none of the first-tier telcos offer VoIP phone lines yet. Perhaps this is one of the reasons why second-tier telcos are fast gaining the market share.

One thing to say about the quality of VoIP phone lines in New Zealand is that it is excellent. New Zealanders are very much used to the best experience while using digital business phone lines. This means that in order to compete with the traditional phone lines, the second-tier telcos had to put together a service that would compete well. From my experience working with two of the major second-tier providers CallPlus and Orcon, their service is a good match to the Telecom's old ISDN service.

At Vadacom

Many people think that we provide VoIP phone lines. We don't. What we do, is develop world's best telephone system, called VadaXchange.

However, to make it work for our customers, we would partner with phone line providers do deliver a turn-key solution for business.

Our system would work in either just the IP Telephony mode, with the traditional phone lines (mostly ISDN), or it can do VoIP throughout, or a mixture.

We are amongst the most experienced in this area in New Zealand, as we started integrating VoIP phone lines back in 2005 when most other business phone system providers stayed well away from it.


So, talk to us, if you are investigating VoIP in New Zealand.

  1. Strange you say that none of the 3 first tier telcos don't offer VOIP services when Telstraclears website says different.

  2. As Nathan has correctly pointed out - TelstraClear do indeed have VoIP on offer and have done so for years now. Both in the form of SIP trunks and hosted VoIP solutions(that include IP tel).
    To add to what Igor laid out as a good foundation for understanding VoIP and IP tel is the all important question of Toll bypass. The reason so many people are asking this question is because of the cost benefits it promises and not purely for the sake of underlying technology. One distinction that needs to made here is VoIP as a technology and Voice over broadband, where one uses the internet feed to carry voice as opposed to the PSTN. With the latter you have the the benefit of bypassing Tolls but no guarantee of voice quality (as it is traversing a public network designed for data , prone to lag and jitter).
    As for the comment about the quality of VoIP phone lines being 'excellent' well that really depends on the quality of the network.
    If you are using an internet feed from the incumbent telco to run voice over it, the quality of the voice is only as good as the network they have - which could be as old as my grandfather in places, often providing a poor internet experience and voice at the mercy of it. The question then is do you really want to run a business over a line that sounds like Skype?
    The newer Telco's (like TCL)on the other hand have dedicated fibre/ copper lines that connect their VoIP network to the PSTN - thus giving you both newer technology with the guarantee of voice quality.

  3. Interesting, looks like Vodafone is joining in http://www.nbr.co.nz/article/vodafone-launches-voip-service-small-businesses-aw-100051#comment-193255

  4. I'd like to point out that Gen-i / Telecom offer VoIP and SIP solutions to their clients and have done for at least two years.

  5. Ivan, I know Gen-i has good IP telephony expertise and offers a number of IP telephony systems to business. Unofficially, they may even deliver the calls via VoIP from a switch hosted by Gen-i.

    However, I haven't seen any official VoIP phone lines from Telecom has yet been launched.

    Do you work for Gen-i? Can you clarify further?

  6. Currently I believe all VoIP offerings are "integrated solutions" rather than "VoIP lines" as such. Gen-I / Telecom do offer SIP trunks via the GVC (Gen-i Voice Connect) service. I guess it depends on the terminology one uses. :-)
    Hope that helps.

  7. Kordia provide SIP trunks via our OnKor Voice service (http://www.kordia.co.nz/telecommunications-solutions/core-offerings/onkor-voice). In fact Kordia is the first company in NZ to get Microsoft certification for our SIP trunks (http://www.kordia.co.nz/_blog/What's_new/post/KORDIA_FIRST_TO_ACHIEVE_MICROSOFT_CERTIFICATION_/).

  8. Good point, Nigel, I've learned of Kordia's SIP after writing this blog.
