VoIP allows you to make telephone calls using a computer network, over a data network like the Internet. VoIP converts the voice signal from your telephone into a digital signal that travels over the internet then converts it back at the other end so you can speak to anyone with a regular phone number. When placing a VoIP call using a phone with an adapter, you’ll hear a dial tone and dial just as you always have.

VoIP may also allow you to make a call directly from a computer using a conventional telephone or a microphone. Voice conversations are turned into digitized data and packetized for transmission across a network.
