VoIP is an acronym that stands for Voice over Internet Protocol. It is a technology that converts voice into digital signals, which are then transmitted over the internet. VoIP uses packet-switched protocols which enable traditional telephone service to be conducted over any computer network. Packets are similar to electronic envelops, which are sent over a computer network.
VoIP allows a person to make calls directly from a computer, VoIP Phone, or any other data-driven device. VoIP can also be referred to as IP Telephony, Internet Telephony, Broadband Telephony, or Broadband Phone Service (AT&T Business, n.d.). With VoIP, someone can make calls from anywhere and anytime as long as they have an internet-connected computer or smartphone.
Since VoIP utilizes packets, it can transmit much more information than the traditional telephone, which consisted of a telephone handset and copper wire connections. VoIP enhances communication, given that multimedia information can also be transmitted over the internet. VoIP has facilitated video-calls and web conferences which have enabled businesses to be more productive. Moreover, international or long-distance calls are generally free when a person uses VoIP technology. This is because the only charge incurred is internet connectivity from the Internet Service Provider (ISP).
