Voice over Internet Protocol - VoIP

What is VoIP?

It’s fun to say – but what is VoIP, really? 

VoIP stands for Voice over Internet Protocol, and basically, it's any call that takes place over the internet or a data connection (versus a landline or mobile telephone network). The call audio is converted into digital signals sent as data. VoIP can also be called IP telephony.  


The benefits of VoIP  

So, what’s the big deal about. VoIP? Well, sending a call via digital signals rather than analogue has a whole host of benefits. For one, it’s a lot cheaper! VoIP doesn't need physical (analogue) phone lines, and it's a great, affordable way of managing an unlimited number of calls. VoIP makes it a lot easier to call friends and family around the globe at low or no cost, rather than dealing with the old-fashioned charges of calling long-distance on analogue.  

VoIP is what enables app-to-app calling. Have you ever called someone using WhatsApp, Messenger, or FaceTime? Say thanks to VoIP!
