What is VoIP or Voice over IP?

VoIP, or Voice over Internet Protocol, is a new cutting-edge communication technology that allows you to use phone calls through your broadband connection rather than a traditional landline. Functioning as an open standard for establishing calls over the Internet, some may also know it as Voice over IP.

A typical configuration of VoIP would be a router for internet connectivity that is then paired with a handset. This handset or business phone system utilises the internet to transmit your voice, similar to a conventional landline. The key distinction lies in the technology itself, which relies on the internet rather than traditional phone line infrastructure.

Phone service providers embrace VoIP to deliver telephone services to customers, eliminating the need for installing and maintaining physical phone lines and equipment. VoIP not only facilitates high-quality calls but also introduces advanced features typically unavailable with traditional landline services.

How does VoIP work?

VoIP transforms your voice into a digital format, compresses it, and then transmits it over the internet. The initiation and setup of the call are facilitated by the VoIP service provider, similar to your internet service provider.

Telephone conversations use small data packets to exchange information, and the internet can transmit these packets globally in less than a second making it more efficient than a telephone system. 

Voice over Internet Protocol eliminates the need for traditional telephones in businesses altogether. As long as you have a broadband internet connection, such as DSL, cable, or fiber, VoIP can be seamlessly integrated within your business.

Example of how VoIP Works

  • Your VoIP-enabled device, such as an IP phone or softphone, connects to your Local Area Network (LAN) through a switch or router.
  • When you dial a telephone number, your IP phone sends a request to your VoIP service provider, indicating the desire to establish a call with the specified number.
  • Fuse 2 as your VoIP service provider processes your request and establishes a connection with the intended party. This involves the initiation of a session and the allocation of resources for the call.
  • Once the call is set up, data packets containing voice information are exchanged between your IP phone and the VoIP service provider. These packets carry the audio signals of your conversation.
  • Your VoIP phone converts the received digital signals back into analog sound signals that can be heard. This transformation ensures that the recipient hears a natural, recognizable voice.
  • The call is now in progress, allowing for two-way communication between the VoIP-enabled devices, and the conversation continues until one party ends the call.
  • When you or the other party ends the call, the VoIP service provider concludes the session, freeing up resources and ending the data exchange between the devices.

How to make a call with VoIP?

To make a  VoIP call, you’ll first require a VoIP business phone service, like Fuse2, and a robust internet connection with ample bandwidth, typically facilitated through high-speed broadband.

Afterward, you can make VoIP calls using any of the following devices:

Existing Phone Handset

Connect your current phone to the VoIP system using an ATA (analog telephone adapter), providing it with an IP address. Simply plug your phone into the ATA instead of directly into the wall socket.

Special IP Phone

Resembling a traditional analog phone, an IP phone features a handset with buttons, but instead of an RJ-11 phone connector, it has an RJ-45 connector. Plug it into an ethernet port on your router. Some VoIP companies might offer a complimentary IP phone depending on the season.


Utilise a VoIP app, often termed a ‘softphone,’ to make calls over VoIP. Ensure your computer has a sound card, and use either a headset or a microphone and speakers. Connect to the internet via ethernet or WiFi. Most reputable VoIP companies offer apps for both Windows and Mac.

Mobile Phone

Install the appropriate app and connect to WiFi for VoIP calls on your mobile phone. Alternatively, use a mobile data plan with 4G or higher speeds. VoIP apps generally support both Android and Apple iPhone (iOS) devices.

VoIP vs Landlines?

VoIP technology facilitates superior voice calls over the Internet, in contrast to landline phones that depend on a copper telephone network for both outgoing and incoming calls.

Deploying VoIP is streamlined through cloud management, eliminating the necessity for on-site installation or maintenance. Adding or modifying users becomes a software adjustment rather than requiring the intervention of an engineer.

Businesses opt for VoIP due to its enhanced calling quality and extensive feature set, all achieved without the complexities and costs associated with establishing an on-premises private branch exchange (PBX).

We would highly recommending switching to VoIP if:

  • Our nation is phasing out landline phones.
  • You’re experiencing subpar sound quality.
  • You require advanced features.
  • The contract for your on-site PBX is reaching its expiration.
  • Transitioning to remote or hybrid work is on the horizon.
  • Excessive costs for external calls are a concern.
  • High expenses for long-distance international calls are an issue.

Still considering a switch to VoIP?

changes in the telecommunications landscape, particularly the gradual phase-out of traditional landline services in parts of the US and UK, make transitioning to VoIP a strategic necessity. The Federal Communications Commission (FCC) has officially announced the phasing out of traditional landline phone services, primarily driven by the costly maintenance associated with landlines. Consequently, VoIP solutions emerge as the inevitable and optimal choice for modern communication needs.

History of VoIP

In the 1970s, researchers delved into the potential of using internet protocols to connect phone systems, a time when dialing into bulletin board systems (BBS) for message exchange was prevalent.

During this era, the expense of long-distance phone calls spurred innovations in real-time digital voice networks, enabling live voice conversations over early data networks. The 1990s witnessed the emergence of the first commercial VoIP applications, facilitating voice calls directly from computers.

VoIP technology underwent continuous advancements in the 1990s and 2000s, introducing crucial features such as video conferencing and further standardizing the handling of calls within VoIP systems.

Today, VoIP has largely supplanted analog phone lines, transforming voice calls into digital transmissions over the internet rather than through traditional phone lines. The advantages of VoIP encompass lower costs, enhanced features, and increased flexibility compared to legacy landline systems. As a result, VoIP has become an integral component of modern business phone and communication systems.

What’s the future of VoIP with AI?

The learning capabilities inherent in AI signal a progressive evolution for VoIP systems, making them smarter and more efficient. AI in VoIP isn’t just a passing trend; it signifies a leap into a future where communication becomes increasingly interactive, responsive, and streamlined. As we venture into a future propelled by the boundless potential of AI, it’s evident that AI VoIP is reshaping the communication landscape, revolutionising each call.

The future of AI within VoIP holds immense promise, ushering in unprecedented improvements in communication. With businesses embracing this cutting-edge technology, the realm of possibilities is set to expand, propelling us toward a future where intelligent, seamless, and efficient communication becomes the standard.

How can i setup VoIP?

For a modest setup, all you require for initial setup is a subscription to your business VoIP provider and a device for making calls. This device could be a desk phone, a laptop with a softphone, or a VoIP app on your mobile phone.

Assuming you already possess a broadband connection and a router, no additional VoIP equipment is necessary.

For medium-sized businesses and larger corporations, managing VoIP may involve opting for a dedicated firewall or switch in addition to the router. In cases where there are existing analog phones or other devices to be retained, the use of an analog telephone adapter (ATA) becomes essential. These compact adapters bridge your VoIP solution with traditional telephone services and devices, accommodating items such as old fax machines and alarm systems. The needs for VoIP setup expand with the scale of the enterprise.
