Videotelephony is the use of audio and video for simultaneous two-way communication. Today, videotelephony is widespread. There are many terms to refer to videotelephony. Videophones are standalone devices for video calling. In the present day, devices like smartphones and computers are capable of video calling, reducing the demand for separate videophones. Videoconferencing implies group communication. Videoconferencing is used in telepresence, whose goal is to create the illusion that remote participants are in the same room.
The following tables compare general and technical information for a variety of audio coding formats.

Microsoft RoundTable was a videoconferencing device with a 360-degree camera that was designed to work with Microsoft Office Communications Server 2007 or Microsoft Office Live Meeting. RoundTable provided remote meeting participants with panoramic video of everyone sitting around the conference table. In addition, RoundTable contained active speaker detection technology that provides high-resolution video of the active speaker in a meeting, and tracked the flow of conversation in real time, switching between different meeting participants as they speak.
Siren is a family of patented, transform-based, wideband audio coding formats and their audio codec implementations developed and licensed by PictureTel Corporation. There are three Siren codecs: Siren 7, Siren 14 and Siren 22.
G.719 is an ITU-T standard audio coding format providing high quality, moderate bit rate wideband audio coding at low computational load. It was produced through a collaboration between Polycom and Ericsson.
Wideband audio, also known as wideband voice or HD voice, is high definition voice quality for telephony audio, contrasted with standard digital telephony "toll quality". It extends the frequency range of audio signals transmitted over telephone lines, resulting in higher quality speech. The range of the human voice extends from 100 Hz to 17 kHz but traditional, voiceband or narrowband telephone calls limit audio frequencies to the range of 300 Hz to 3.4 kHz. Wideband audio relaxes the bandwidth limitation and transmits in the audio frequency range of 50 Hz to 7 kHz. In addition, some wideband codecs may use a higher audio bit depth of 16 bits to encode samples, also resulting in much better voice quality.
Lifesize is a video and audio telecommunications company in the United States which provides high definition videoconferencing endpoints and accessories, touchscreen conference room phones, a cloud-based video collaboration platform, and omnichannel contact center solutions under their CxEngage product line.
