IP Phone technology is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN). The steps and principles involved in originating IP Phone calls are similar to traditional digital telephony and involve signaling, channel setup, digitization of the analog voice signals, and encoding. Instead of being transmitted over a circuit-switched network; however, the digital information is packetized, and transmission occurs as IP packets over a packet-switched network. They transport audio streams using special media delivery protocols that encode audio and video with audio codecs, and video codecs.
Because of the bandwidth efficiency and low costs that IP Phone technology can provide, businesses all over the world are migrating from traditional copper-wire telephone systems to IP Phone systems to reduce their monthly phone costs.IP Phone technology aimed at businesses have evolved into unified communications services that treat all communications — phone calls, faxes, voice mail, e-mail, Web conferences, and more — as discrete units that can all be delivered via any means and to any handset, including cellphones.
