Voice over Internet Protocol (VoIP) allows you to make telephone calls using an Internet connection instead of a regular telephone line. Some VoIP services may allow you only to call other people using the same service, but others may allow you to call any telephone number - including local, long-distance, mobile, and international numbers.
First, you need an Internet connection, and, for many types of these calls, you need a broadband Internet connection.
Depending on the service you purchase, you may need a computer, a special VoIP phone, or a regular phone with an adapter. If you are calling a regular phone number, the person you are calling does not need any special equipment, just a telephone.

Using VoIP Service
If you use a VoIP phone or a regular phone with an adaptor, you place and receive calls much like you do with regular phone service. If you use it with your computer, a phone icon usually appears on your computer screen. Clicking the icon allows you to dial numbers from a pad, or dial a call by clicking on a contact's preprogrammed name and number. You will then hear a ring just like any other call. Computer-based VoIP services have a variety of ways of notifying you that you have an incoming call.
