VoIP can be many things . . .
Here's a nice formulation from Yahoo News, FCC Tries To Defuse AT&T Internet Telephony Controversy:
". . . VOIP can be many things.
At one end of the scale is AT&T's use of its Internet backbone to deliver long-distance calls. Such calls could be dialed from an old black rotary phone by a Verizon Communications (NYSE:VZ - News) customer in New York, converted by AT&T to digital packets and carried over its Internet backbone, and converted back again by AT&T in Houston, where it is received on another plain, old telephone by an SBC customer.
At the other end of the scale is Pulver.com's Free World Dialup. The service is available only to members, doesn't use phone numbers, and sidesteps the phone network entirely with special phones that communicate with each other over broadband Internet connections.
In the middle is Vonage Holding Corp. Customers make calls with a broadband connection, but Vonage can deliver the call to a conventional phone on the public switched network."
