What is VoIP?
VoIP (Voice over Internet Protocol) allows you to make telephone calls over an Internet connection rather than over a conventional telephone network. VoIP converts your voice signal from your telephone into a digital signal that travels over the Internet and converts it back at the other end so you can speak to anyone with a regular phone number.
How does VOIP work?
Analog phone signals need to be converted into digital signals to be transferred over the internet.
