Voice over Internet Protocol (VoIP) is a technology that allows users to make voice and video calls over the Internet in NZ rather than using traditional telephone lines. Instead of relying on a dedicated network of wires and hardware, VoIP converts analog voice signals into digital data packets and sends them over the Internet to the recipient.

This method is more cost-effective than traditional phone lines and offers a wide range of features and benefits, such as call forwarding, video conferencing, and international calling. It is becoming increasingly popular in residential and business settings and is expected to grow as internet speeds and connectivity improve.

All You Need to Know About How VoIP Works in New Zealand

It works in New Zealand by converting analog voice signals into digital data packets and transmitting them over the Internet. Here’s a step-by-step overview of how to do this;

  • First, the user speaks into a microphone or handset, which converts the sound waves into analog signals.
  • These analog signals are then converted into digital data packets using a codec (coder-decoder) algorithm.
  • The data packets are then transmitted over the Internet to their intended destination. This transmission can happen via a variety of methods, including Wi-Fi, Ethernet, or cellular data networks.
  • When the data packets arrive at their destination, they are reassembled into a digital signal and decoded back into an analog signal.
  • Finally, the analog signal is sent to the receiving party’s phone or device, where it is converted back into sound waves that can be heard by the listener.

VoIP (Voice over Internet Protocol) has several advantages over traditional phone systems. Here are some of the key benefits of using VoIP:

  • Cost savings: It often costs less than traditional phone systems. Because these calls are transmitted over the Internet, no long-distance charges or separate lines are required for voice and data. Additionally, its open-source software can be less expensive to purchase and maintain than traditional phone systems.
  • Portability: With this, you can make and receive calls from anywhere with an internet connection.
  • Flexibility: Its systems can be customized to meet the specific needs of your business. This includes call routing, voicemail-to-email, call recording, and more.
  • Scalability: Its systems can easily scale up or down to meet your changing business needs.
  • Integration: VoIP systems can integrate with other business applications, such as CRM software or email clients, to provide a more streamlined communication experience.
Key Features and Benefits​


While the Voice over Internet Protocol has many advantages for New Zealanders, it also has some disadvantages that should be considered. Here are some of the key disadvantages of using it.

  • Dependence on Internet connection: Because it relies on an internet connection, if the Internet goes down or is slow, call quality can suffer, or calls may be dropped entirely.
  • Power outages: In the event of a power outage, VoIP systems may not work, as they require power to operate. Some providers offer backup battery options, but these typically only last for a limited time.
  • Quality of Service (QoS) issues: VoIP calls can be affected by network congestion or other issues that can impact call quality. However, QoS issues can be mitigated with proper network configuration and monitoring.
  • Security concerns: VoIP systems can be vulnerable to hacking, viruses, and other security threats. Encryption and other security measures can help mitigate these risks.

Overall, while VoIP offers many advantages, it is important to consider the potential downsides and ensure that your system is properly configured and secured.

  • Choose your hardware: To make and receive calls, you will need open-source hardware, such as a VoIP phone or an adapter that connects to your regular phone.
  • Set up your account: Once you have chosen your service provider, sign up for an account and configure it with your hardware.
  • Configure your network: It may require some network configuration, such as opening certain ports on your router or setting up the quality of service (QoS) to prioritize the traffic over other internet traffic.
  • Test it: Test your connection by making a few calls and adjusting your hardware and network settings to improve the voice quality.
    Enjoy your service.
