What Does Internet Protocol Telephony Mean?<\/span><\/h2>\n

Internet Protocol Telephony (IP Telephony) is the use of IP-based networks to build, provide and access voice, data or other forms of telephonic communications. IP telephony provides traditional telephonic communication over an IP-based network, the Internet – via an Internet service provider (ISP) – or directly from a telecommunications service provider.<\/p>\n

Techopedia Explains Internet Protocol Telephony<\/span><\/h2>\n

IP telephony is designed to replace the telecommunications’ infrastructure of circuit switched public data networks (CSPDN) and public switched telephone networks (PSTN) with packet switched IP communication networks. <\/p>\n

In a consumer IP telephony solution, a soft IP phone application and backend Internet connection enable voice and data communication, such as calling and faxing. A user may call other softphone users, send or receive faxes and even communicate with circuit switched and cellular communication services. <\/p>\n

In an enterprise environment, IP telephony is implemented through physical IP phones that work on top of an IP network infrastructure. An IP phone’s built-in firmware provides the complete functionality for initiating and managing telephonic communications. Moreover, IP telephony also supports video communication between two or more users.<\/p>\n

Voice over Internet Protocol (VoIP), a popular IP telephony implementation, only supports voice communication over IP.<\/p>\n","protected":false},"excerpt":{"rendered":"
