Free Internet Calling Services

As technology is booming, the world is becoming smaller and smaller. Your company is expanding, or you have friends all over the world, with whom it is expensive to stay in contact with if you use the traditional telephony. Luckily, Internet technology has also been developing on a large scale, so now you can also use it for free communication. This article will tell you how.

Internet Calling is based on VoIP technology. Voice over Internet Protocol means the order of transmission of multimedia and voice data over the Internet. In this process, voice signals are converted first, then packed into data packets according to codecs, for faster transmission.

Then those packets are transmitted to the device of the callee, and converted back into voice signals in the correct order. That is what the callee will hear.

This technology made it possible to stay in contact with friends and customers all over the world with no charge if the Internet is used for transmission.

It means that whenever you would like to call someone and both of you use your computer, then you can call each other at a low cost, but if one of you only has a phone instead of a PC, then the Internet is not enough for data transmission, so you will have to pay some money for the call.

Free PC to PC calling is provided by the following programs (Figure 1):

  • Skype
  • Google Voice
  • Fring
  • Windows Live Messenger (formerly known as MSN IM)
