VoIP Telephone Systems – The Ultimate Guide to VoIP Telephone Systems

In this guide we discuss everything there is to know about VoIP telephone systems.

What is VoIP?

Standing for ‘Voice over Internet Protocol’, VoIP telephone systems enable you to make and receive phone calls through the internet as opposed to a mobile network or traditional landline. Whereas regular telephone services use Public Switched Telephone Network (PSTN), VoIP phone services utilise an internet connection to deliver voice calls.

It’s worth noting that VoIP is also often referred to as Internet Telephony, IP Telephony, Voice over Networks (VoN), and Voice over Broadband (VoB) among other names.

How Does VoIP Work?

VoIP telephone systems work by converting your voice into a digital signal before compressing it and sending it over the internet. This digital data is then sent to its destination and uncompressed into the sound that you hear through your handset or speaker.

Providing you have a high speed and reliable internet connection you’ll be able to use a VoIP telephone system. You’ll also need a SIP-compatible desk phone so that it is assigned an IP address and can thus make calls from your network.

As VoIP operates over the internet, all your data is stored securely in the cloud. Your VoIP system can be managed via an online dashboard, where you can add new contacts, adjust numbers and so on.

Benefits of VoIP

Reduced Costs

Not only do the initial set-up and ongoing costs for a VoIP telephone system tend to be far less than a traditional phone system, but as it operates off your internet connection, you don’t need to pay for lots of individual phone lines.

Calls over the internet from one VoIP system to another VoIP system are free. Calls from a VoIP system to a landline usually incur a cost (albeit a considerably smaller one than a traditional phone line).

More Accessible

With VoIP, the location and/or distance between the person you are calling has no impact. It doesn’t matter if you are making a call to someone on the other side of the world, as long as you both have a good internet connection, you’ll be able to communicate.

High-Quality Calls

Assuming you have a strong internet connection, the quality of calls made via VoIP are crisper than alternative voice call options as they have a higher quality audio range.


VoIP telephone systems allow you to stay connected wherever you are in the world. So, if for example, you are often away from the office and want to remain connected, VoIP can be easily integrated with your business mobiles.


Unlike private internal networks where you are limited to how many phones can be added by the number of lines available in the system, with a VoIP network you are only limited by bandwidth, meaning thousands of connections can be made if required – in other words, adding new users is simple and easy.

What Does VoIP Cost?

The cost of a VoIP telephone system will vary from provider to provider. However, it is generally far less expensive than a conventional phone system. This is because you don’t need any additional infrastructure to set-up your VoIP system – it will utilise the internet connection you already have available, meaning that you won’t need to pay fees to install wiring. Also, unlike calls made over the PSTN, the distance and length of VoIP calls won’t impact cost.
