VoIP (Voice over Internet Protocol) is a great technology that allows you to make and receive telephone calls over the Internet and has been in the mainstream now for going on 9 years. It can also be referred to as an Internet Phone. VoIP (Voice over IP) enables you to make cheap telephone calls over a broadband Internet connection, (usually a DSL, broadband cable connection, or T1), instead of using your regular telephone service.
What is necessary for VoIP technology is the use of the same protocols that the Internet uses. (A protocol is a set of rules used to allow orderly communication.) Thus, voice over Internet protocol means voice that travels by way of the same protocols used on the Internet. VoIP is often referred to as IP telephony (IPT) because it uses Internet protocols to make possible enhanced voice communications.
