What is VoIP?
VoIP (Voice over Internet Protocol) converts your voice into a digital signal that travels over the Internet. If you are calling a regular phone number, the signal is converted to a regular telephone signal before it reaches the destination. VoIP allows you to make a call directly from a computer, a special VoIP phone, or a traditional phone connected to a special adapter. Special VoIP phones plug directly into your broadband connection and operate much like a traditional telephone. If you use a telephone with a VoIP adapter, you will be able to dial just as you always have and still receive a dial tone.
