VoIP – Voice over IP

[ad_1]

Voice over IP, or VoIP, is a family of technologies that enables voice applications and telephony to implement an Internet Protocol (IP) network like the Internet.

These technologies include protocols, hardware and software standards, and computer programs. VoIP is employed in telephony applications, from analog phones to next-generation IP phones and wireless headsets, and in desktop voice chat services, from web-based party-line chat services (like Yahoo! Chat) to the well-known Skype desktop voice -calling service.

VoIP has become an important technology that is integrating pervasively into the popular culture. It is employed daily to drive new engines of commerce everything from business-class VoIP-powered calling services to simple desktop chat tools such as Apple's iChat. Other high-profile companies like eBay, Microsoft, Google, and AT & T offer applications and services that utilize VoIP, too.

These big companies have recognized that the popular culture is moving to VoIP services en masse, even as the telecom industry is being set on its ear by scrappy young VoIP startups like Vonage, Packet8, and SpeakEasy.net. VoIP services deliver telephony applications less expensively than the old phone companies can hope to. This is because VoIP is free of the constantly burdensome legacy technology investment the old phone companies must make to keep the "old" global phone network running. VoIP is also free of the endless government regulations and tariffs imposed upon the old phone companies.

In a nutshell, the way society looks at the voice network has changed. VoIP is the enabler of the change, and tomorrow's global voice network is the Internet.
