What is VOIP?
VoIP (Voice over Internet Protocol) is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line. VoIP takes analog audio signals from your phone and turns them into digital data, and transfers them over the Internet. VoIP works just like a regular phone, but instead of using the high priced telephone company’s wiring, VoIP routes your phone calls directly to your telephone using your high speed internet connection. What’s changed is that you don’t pay a big bill to use the phone company’s wires.
How Does it Work?
A phone using Voice over Internet Protocol (VoIP) will initiate a call. The VoIP server (SIP) will check if the call is to be routed to another VoIP account on the same server, and if so, proceeds to forward the call to the called party at no cost. This call is termed as ON-NET. Should the server fail to locate the number in its records, the call is forwarded to the destination as an OFF-NET call and charged as per rate card.
