VoIP or “Voice over Internet Protocol” is the technology that allows digitized audio to be transmitted over Intranets and the Internet. Using this technology, you can make and receive phone calls using your broadband or high speed Internet connection instead of your standard phone line.
Analog voice is translated into SIP(Session Initiation Protocol) packets that transverse the public Internet. Your calling experience will be identical to what you have always had. VoIP is also known as Internet telephony.
