VoIP, or Voice over Internet Protocol, is a form of technology which allows users to use the internet to make calls rather than the traditional analogue phone system.

When a call is made, it is routed from one mobile or VoIP provider to the next until it gets to its destination, a process known as wholesale voice termination.

In the UK today there are more than three million subscribers to VoIP, and this is increasing by a staggering 21% year on year. But just why are people changing to VoIP and what are its benefits for small businesses?

Save Money

The biggest benefit of using VoIP is the cost savings that can be made. You can say goodbye to those high call charges, both UK and internationally. That’s because rates for VoIP are normally much lower than traditional ISDN or analogue phone calls thanks to Wholesale Voice Termination firms offering low prices because of their minimal overheads. In addition to this, you can reduce the amount you spend on expensive line rentals for analogue and ISDN by using the internet for your calls instead.

Numerous Features

Many VoIP providers offer a range of additional features, including voicemail to email, call recording, fax to email, conference calls, data sharing via video and music on hold, among other things.

Added Professionalism

If you’re a small business or a freelance, then using a VoIP can add a touch of professionalism to your business. Features like welcome greetings along with department selection choices as well as the features mentioned above can give an impression that your business is larger than it actually is.


When using a VoIP system, you can use your phone all over the world as long as you have a broadband connection. VoIP systems are also accessible through email when you are travelling. All you need is a headset or IP phone and you’ll be able to contact your staff and clients as and when you need.


BT will switch off the ISDN network come 2025, so VoIP offers a longer-term solution to a company’s telephone requirements. As VoIP uses an internet connection for calls and is hosted on the Cloud, you can take your phone with you should you need to relocate. This means no changing of numbers or having to move a cumbersome telephone system.
