What is VoIP?

Have you ever used an app such as WhatsApp or Facebook messenger to make a phone call? Then you have used VoIP before – a lot of people have used IP telephony without realising! 

VoIP stands for ‘voice over internet protocol’ and in simple terms it means voice transmitted over a digital network.

Often referred to as IP telephony, VoIP uses Internet protocols to make enhanced voice communications which offers many benefits, such as greater flexibility, scalability and lower call costs. VoIP allows you to make calls over the internet, those calls are usually free or very low cost. It can take months to install a standard ISDN line – however, a cloud-based system can achieve this almost instantly at a much lower cost.

To make a VoIP call, you need a high speed broadband connection and you can either use a soft-phone on your PC/laptop or a purpose built VoIP telephone. Using a VoIP service allows you to call anyone, anywhere on any type of network – the call quality of a VoIP phone will sound identical to an ordinary telephone call, the voice quality is crisp and clear.

VoIP allows your business to be more flexible. If you travel often, VoIP would be great for you – your telephone service can be used wherever you travel as long as you have access to a high speed internet connection, your computer doesn't have to be turned on to make the calls - however, your broadband needs to be active.
