VoIP is an acronym for voice over internet protocol. A VoIP, in essence, is a computer phone that allows you to make phone calls from your computer to anyone in the world, e.g., PC to PC, PC to landlines, or PC to cell phones. The voice signal converts to data packets and travels across the internet through a VoIP platform, and then converts back to voice at the receiving end of the communication exchange.
