The Red Indians sent smoke signals to communicate among themselves and the soldiers used Morse code during the WWI. However, the golden day when a wonderful person and a marvellous inventor called Alexander Graham Bell invented the telephone, bought with it not only a sunny morning but a new way to communicate. Since then telephone lines have been an integral part of the human life and has created an identity of its own.

Another major event took place when the internet was bought into the communication sphere by the English scientist Timothy Berners Lee and since then the world of communication has never been the conventional one that is normally associated with communication mediums. Many events have taken place which have introduced new technologies as well as new concepts altogether.

The ability now to use the features of a telephone via the medium of the internet is one of the events mentioned before in the earlier paragraph. Hence a person can now make a call over the internet to another person. Internet calls are therefore now one of the basic tools being used to stay in touch with friends and relatives with national and international borders no longer serving as hindrances in the way of remaining in touch.

The dominant technology behind this has been VoIP which is a completely new entry in the field of technologies which are being used for communication. Voice over IP or Voice over Internet Protocol is a tool which now has made it possible for a person to make phone calls using the internet as a medium for transmission. This can happen both with the personal computer as well as a normal phone as both of them only require the necessary technology and also an internet connection. Hence users can now make internet calls with a phone (with an ATA(Analogue Telephone Adaptor)) or a PC with the required software. Another option exists in the form of a VoIP phone which has the required technology already installed in it.

There is yet another interesting feature associated with this new feature of internet calls and this is the possibility of making free calls where the user can make calls to any location without the need to pay any sort or form of money. This is therefore an attractive new prospect which gives the user to make free internet calls and therefore have a great time doing it given the fact that they have all basic facilities and also additional facilities as well.

VoIP has therefore created a new field of communication with wonderful business prospects as well. This can be explained from the fact that whenever users visit any one of the service provider websites then he will encounter lots of online advertisements either as blinkers or a pop ups. The VoIP service provider websites are perhaps some of the best websites in terms of the number of hits that they receive and are therefore logical as well as good places to put advertisements in. the revenue generated from these companies (they of course can't put their advertisements for free) is used to handle the costs of the calls that are made and this is how the user is able to get completely free internet calls. But the chance for conducting excellent product promotions by putting related advertisements on the VoIP gives the companies a reason to spent the money and hence the system works both ways by increasing the product awareness for the company and generating revenue for the website.

Internet calls are therefore are also utilised by entire organisations for various business reasons and hence VoIP service providers also have another separate target customer group in the form of these organisations. Business is not only dwelling for the service providers but is also on the rise with the emergence of developing countries both in terms of economy and financial capability.
