IP telephony (Internet Protocol telephony) is a general phrase used to describe



technologies that use the Internet Protocol's packet-switched connections to



exchange communications such as voice communications or fax



communications.







Calls travel as packets of data on shared lines using the internet. IP telephony



is an important part of the unification of computers, telephones, and television



into a single integrated information environment. For this reason it is often



referred to as Converged communication.
