Voice over Internet Protocol (VoIP), also known as IP telephony, delivers voice communications via a digital IP network connected to the internet. IP technologies facilitate data delivery services using the same switching & routing mythologies designed for network computers. When multiplexed, voice, fax, SMS, voice-messaging and multimedia data can be transmitted over a broadband public Internet. Rather using a public switched telephone network (PSTN), VoIP systems are essentially ordinary nodes of the network.
VoIP telephone calls vs traditional telephony.
The encoding technology allows the digitization analog voice signals into compressed data packets. The
digital data is then transmitted as IP packets over a switched network. Once
processed, packets are transported as media streams without any additional
