A VoIP phone is a telephone set designed specifically for use in a voice over IP (VoIP) system by converting standard telephone audio into a digital format that can be transmitted over the Internet, and by converting incoming digital phone signals from the Internet to standard telephone audio.

A VoIP phone is a telephone set designed specifically for use in a voice over IP ( VoIP ) system by converting standard telephone audio into a digital format that can be transmitted over the Internet, and by converting incoming digital phone signals from the Internet to standard telephone audio. A VoIP phone allows the user to take advantage of VoIP technology without involving a personal computer, although an Internet connection is required.

Physically, a VoIP phone set resembles a traditional hard wired or cordless telephone set. It employs the familiar ear and mouth ( E&M ) arrangement with an earphone (or earpiece) for listening to incoming audio, and a microphone (or mouthpiece) for transmitting audio. Some VoIP phone sets offer enhanced quality audio, comparable to that on compact disc( CD ). A few VoIP phone sets allow for the transmission and reception of image data during calls, so they can be considered video telephones.
