The most common way VoIP works is that the end user establishes a hi speed broadband connection, a router and a VoIP gateway. Instead of a standard telephone line, the router sends the telephone calls over an internet connection. The VoIP gateway, placed somewhere in direct proximity of the connected Internet converts the analog signals into digital format, which are further broken down into smaller chunks called 'packets', before sending it over the internet, much like the way data is transmitted to and from the computer. These packets are sent to their final destination and instructions for bringing back into an understandable form are embedded in them. It then goes through a VoIP gateway where the packets are reconverted into the original analog format utilizing a PSTN (Public Telephone Switch Network), thereby routing the call to the number the caller has dialed blending old school technology and hi tech delivery in a seamless and instantaneous way.

is available for both Unix/Linux and Microsoft Windows. With one of these free VoIP software packages, you can place PC-to-PC calls across the Internet. Skype is a unique advertiser-supported service which provides free VoIP service for PC-to-PC calls. The key limitation here is PC-to-PC calls -- you cannot place a call to a regular telephone number for free. This is because someone must pay for the infrastructure to connect the Internet to the telephone system and also pay for the call time used on the telephone system.
