VoIP is the abbreviation for Voice over Internet Protocol. VoIP is a technology that allows making voice calls with the use of the broadband Internet connection instead of a regular phone line. Some may allow you to call anyone who has a telephone number, which includes local, long distance, mobile and international numbers whereas other VoIP services may only allow you to call people using the same service. Also, while some VoIP services only work over your computer or a special VoIP phone, other services allow you to use a traditional phone connected to a VoIP adapter.
VoIP works in a way that it converts your voice into a digital signal, which will travel over the Internet. It allows you to directly call from a computer, a special VoIP phone or a traditional phone, which is connected to a special adapter. In addition, wireless “hot spots” in locations such as airports, parks, and cafes allows you to connect to the Internet and may allow you to use VoIP service wirelessly.
