What is a VoIP system?
VoIP stands for ‘Voice over Internet Protocol’. Traditional phones rely on the Public Switched Telephone Network (PSTN) which routes calls across copper cables that are connected by telephone exchanges. VoIP technology, on the other hand, converts your voice into a digital signal so you can make calls over the internet. A VoIP phone system, then, allows you to make and receive calls through the IP telephony network without any limits. Watch the video to find out more about how VoIP works.
