What is VoIP?
Voice-over-Internet
protocol (VoIP,
IPA: /vɔjp/) is a protocol optimized for the transmission of
voice through the Internet or other packet-switched
networks.
VoIP is often used abstractly to refer to the actual transmission of voice
(rather than the protocol implementing it). This latter concept is also
referred to as IP telephony, Internet telephony, voice over
broadband, broadband telephony, and broadband phone.
VoIP providers may be
viewed as commercial realizations of the experimental Network Voice Protocol (1973) invented for
the ARPANET providers. Some
cost savings are due to utilizing a single network to carry voice and data,
especially where users have underused network capacity that can carry VoIP at
no additional cost. VoIP-to-VoIP phone calls are sometimes free, while VoIP
calls connecting to public
switched telephone networks (VoIP-to-PSTN) may have a cost that is borne by
the VoIP user. Voice-over-IP systems
carry telephony signals as digital audio, typically reduced in data rate using speech data compression techniques, encapsulated in a data-packet stream over IP. There are two types of
PSTN-to-VoIP services: Direct inward dialing (DID) and access
numbers. DID will connect a caller directly to the VoIP user, while access
numbers require the caller to provide an extension number for the called VoIP
user. Voip text is sourced from wikipedia.org and available under the terms of the GNU Free Documentation License. (See Copyrights for details.)
