Calling long-distance cheaply
There are many companies offering VoIP (voice over Internet protocol), which allows free or discounted international calls that travel mostly through the Internet, saving on long-distance charges.
The major provider is Skype (www.skype.com), with over 300 million users. Skype allows one to make computer-to-computer calls through the Internet for free no matter one’s location in the world. (For a computer without a built-in microphone and speaker, a headset is required.)
