Essential VoIP Basics for Businesses


Share this post

By now, most businesses have encountered Voice over Internet Protocol (VoIP). It’s a technology that’s matured, becoming increasingly popular in both commercial and domestic settings. But it remains misunderstood.

For small and medium businesses, VoIP can seem overwhelming and complicated. While the technology promises increased efficiency and considerable cost savings, it’s surrounded by myths and misconceptions.

The reality is that VoIP represents a big opportunity for businesses. So read on to learn a few VoIP basics – and find out what it could do for your organisation.


In its simplest terms, VoIP allows you to make telephone calls using a data connection as opposed to an analogue or digital line. It’s a method of communication, not the means.

So whether you’re making calls on an internal network, using an ISDN line, or working on more recent broadband, VoIP is the technology that allows you to send and receive voice communications.


The biggest advantage of using VoIP is unlocking new flexibility. That’s why it’s so ideal for small and medium businesses where agility is so important. You can choose to blend your call traffic with your data on the same line, or implement a dedicated line for voice data. Then, once your VoIP systems is up and running, there’s no need to make changes to your physical infrastructure.

If you need to reroute calls, this is a matter of one or two minutes connect from a new location, or add a new line, you won’t be waiting for your provider to make physical changes. Your phone system can simply scale to meet demand, and instantly change to suit your changing requirements. This flexibility allows you to respond to unexpected changes, and always get the service you need, as soon as you need it.


In its infancy, VoIP had a reputation for poor call quality. Today, this is thankfully a thing of the past. While VoIP technology has always been capable of delivering high quality call audio, wider infrastructures didn’t always make this possible. The inefficiencies of our data lines and the way data was transferred led to noticeable artefacts and imperfections on calls. Modern data connections are faster and more efficient – ideal for the demands of VoIP.

VoIP itself has evolved and matured, with better encoding and transfer methods. This ongoing development continues all the time – VoIP has established itself as the future of calling, and its performance will only continue to improve.


We live in a data-driven world, where we are all seamlessly connected by the internet. With that in mind, it’s no surprise that data networks are the most cost-effective way to make phone calls. Depending on your service provider, VoIP calls could be charged at a single, consistent rate, no matter where in the world you are calling.

Common tasks like adding new lines to your VoIP service aren’t as labour-intensive as adding new analogue lines – so they’re more affordable too. Best of all, you never have to carry an unnecessary overhead costs.

VoIP is a mature technology, and it’s time for businesses of all sizes to take advantage of its benefits. If you need help understanding what VoIP could do for you, don’t hesitate to get in touch.
