IP telephony[edit]

Main article: Voice over IP
A commercial IP telephone, with keypad, control keys, and screen functions to perform configuration and user features.
The field of technology available for telephony been broadened with the advent of new communication technologies. Telephony now included the technologies of Internet services and mobile communication, including video conferencing.
The new technologies based on Internet Protocol (IP) concepts are often referred to separately as voice over IP (VoIP) telephony, also commonly referred to as IP telephony or Internet telephony. Unlike traditional phone service, IP telephony service is relatively unregulated by government. In the United States, the Federal Communications Commission (FCC) regulates phone-to-phone connections, but says they do not plan to regulate connections between a phone user and an IP telephony service provider.[citation needed]
A specialization of digital telephony, Internet Protocol (IP) telephony involves the application of digital networking technology that was the foundation to the Internet to create, transmit, and receive telecommunications sessions over computer networks. Internet telephony is commonly known as voice over Internet Protocol (VoIP), reflecting the principle, but it has been referred with many other terms. VoIP has proven to be a disruptive technology that is rapidly replacing traditional telephone infrastructure technologies. As of January 2005, up to 10% of telephone subscribers in Japan and South Korea have switched to this digital telephone service. A January 2005 Newsweek article suggested that Internet telephony may be "the next big thing".[3] As of 2006, many VoIP companies offer service to consumers andbusinesses.[needs update]
IP telephony uses an Internet connection and hardware IP phones, analog telephone adapters, or softphone computer applications to transmit conversations encoded as data packets. In addition to replacing plain old telephone service (POTS), IP telephony services compete with mobile phone services by offering free or lower cost connections via WiFihotspots. VoIP is also used on private networks which may or may not have a connection to the global telephone network.

Erlang Example Question A subscriber makes 3 phone calls of 3 minutes, 4 minutes , and 2 minutes duration in 1 hours period. Calculate Minutes of traffic in the hour = number of calls x duration Minutes of traffic in the hour = (4min+3min+2min) Hours of traffic in the hour    = 9 minutes / 60 minutes Hours of traffic in the hour   = 0.15 Traffic of traffic in the hour  = 0.15 Erl
