Voice over Internet Protocol (VoIP), is a technology that allows you to make telephone calls using a broadband Internet connection instead of a regular/analog phone line. Some services using VoIP may only allow you to call other people using the same service for free, but others may allow you to call anyone who has a telephone number - including local, long distance, mobile, and international numbers at a small fee. Also, while some services only work over your computer or a special VoIP phone, other services allow you to use a traditional phone through an adaptor usually USB.
