The cheapest way to make calls is to use your computer. You will need a soundcard, a microphone and speakers/headphones, or a headset. Those are pretty cheap these days, and speakers are already built into most laptops. Sound quality is constantly improving and these days it's more than adequate, even if you're calling the opposite side of the world on an average connection. Skype is the leader in this field and works really well. It's very easy to download and install - literally takes a few minutes - and if you have a web-cam the latest version includes video capabilities. Apart from being extremely cool for all of you with friends and family on the other side of the planet, many companies are also implementing Skype as a way to reduce their phone bills. The latest version of Skype works on Windows, Mac OS X, Linux and PDAs (Pocket PC).Nearly all programs for Internet calls work on the same procedure:
Fill in the user registration at the Web site Download the program Buy "phone" time (in some cases PC to PC calls are free)
Make the call
Another means of making inexpensive calls without a computer is with a prepaid card. Accounts can usually be recharged over the Internet or by calling customer service. Some cards also include voicemail, text messaging and a number where family and friends can leave messages for free.
