More and more businesses today have their receive phone service through Internet instead of local phone company lines. Many businesses are also using their internal local and wide-area network infrastructure to replace legacy enterprise telephone networks. This migration to a single network carrying voice and data is called convergence, and it’s revolutionizing the world of telecommunications by slashing costs and empowering users. The technology of families driving this convergence is called VoIP, 
or Voice over IP.
