VoIP or Voice over Internet Protocol has been around for more than a decade now. It was way back during the 1990s, when a company called Vocaltec released PC to PC VoIP software in the year 1995. All you required was a sound card, modem, microphone, and speakers. In this kind of arrangement the so called voice signals were compressed after which these signals were translated to voice packets and transmitted over Internet.


Usefulness of VoIP

One of the greatest advantages of VoIP technology is the standard internet connectivity can be used to make free calls over the Internet. Another advantage is that by making use of these free phone calls, you don’t have to pay the telephone company as you are avoiding them. VoIP has changed the way in which we communicate over the Internet. Such has been the popularity of the technology that several technology giants are opting for this technology for their daily telecommunication usage.

Regardless of the distance that you are calling up, you don’t have to shell out anything extra excluding the ISP charge.

This type of VoIP permits you to connect a normal telephone to the internet and thereafter you can make use of the VoIP technology to make telephone calls.
