To take advantage of any free VOIP services, you will need to have the following:
* An Internet connection: cable, DSL, even dial-up.
* A computer connected to the Internet.
* A microphone or telephone connected to your computer. A phone will need to use a special adapter to connect to the computer. Some free VOIP companies -- like Skype -- have begun to sell special phones enabled for VOIP service. These phones must be plugged into the host computer via a USB connection to work.
