Definition: VoIP is a technology that allows telephone calls to be made over computer networks like the Internet. VoIP converts analog voice signals into digital data packets and supports real-time, two-way transmission of conversations using Internet Protocol (IP).
VoIP calls can be made on the Internet using a VoIP service provider and standard computer audio systems. Alternatively, some service providers support VoIP through ordinary telephones that use special adapters to connect to a home computer network. Many VoIP implementations are based on the H.323 technology standard.
VoIP offers a substantial cost savings over traditional long distance telephone calls. The main disadvantage of VoIP is, like cell phones, a greater potential for dropped calls and generally lesser voice quality.
