This VoIP summary from IEEE Spectrum was cited by the Resource Shelf. It's worth a read:
"Simply put, VoIP means doing voice communications over the same networks that we rely on for data communications—the local networks that connect to our computers and the Internet that links them all together. If you've ever bought a prepaid phone card, especially one for international calling, you've probably already dialed into a VoIP system without knowing it. By crossing national borders as cheap Internet packets, instead of moving through an expensive switched circuit, an international VoIP call, while still billed per minute, costs pennies, not dimes or quarters. In fact, those low costs, and the efficiencies for carriers of maintaining a single, unified telecommunications network, guarantee that all telephony will eventually be done over IP. Essentially everyone in the telecommunications industry agrees on that."
I'm interested in the adoption of VoIP for instruction and would like to hear about applications in higher education. ___JH

VoIP Source: IEEE Spectrum Seven Myths about Voice over IP "Voice over Internet Protocol, or VoIP, is one of the fastest-growing, and most misunderstood, technologies in the world at the moment. Confusion, outdated beliefs, and urban mythology reign over such simple issues as how it works, the quality of the calls, and, of course, how much it costs. VoIP calls are not free now, and they never will be. As things are shaping up, though, they're so cheap that carriers are letting customers make all the calls they want for a single monthly fee, typically US $25 to $35."
