VoIP, abbreviation for Voice over Internet Protocol, 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.

What is VoIP?
VoIP stands for Voice over Internet Protocol (VoIP) and is also alternatively known as Internet Telephony. VoIP allows you to make phone calls over your ISP (Internet Service Provider) connection, instead of your phone company, by sending voice (data) over the internet.
How does VoIP work?
Current telephone system relies on reliable but inefficient method for connecting calls called ‘Circuit’ Switching. When a call is made between two persons, a ‘circuit’ is established and the connection is maintained for the entire duration of the call with a dedicated wire connection between two persons. A long distance call costs high, because of the copper wire that connects all the way from one point to another.
