Definition - What does Voice Over Internet Protocol (VoIP) mean? Voice over Internet Protocol (VoIP) is a technology used for delivering different kinds of data from a source to a destination using IP (Internet Protocol). The data may be in many forms, including files, voice communication, pictures, fax or multimedia messages.
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.
