Remember the days when people would have to place trunk calls through an operator to call long distance? Well, you wouldn't because that seems like something that happened in the last century! Today, communication technology has come so far that it is only natural for long distance calling technology to have evolved as well.

There are many technologies that can subsidise long distance calling. The internet has made it possible to transfer data digitally over the internet line. This is known as the Voice over IP technology. There are well known applications like Skype that use this technology. Calling from one computer to another using VoIP can be free.

But what if you want to call a phone from your computer? That is possible too! Cheap Internet Phone- VoIP calls are now a common thing and quite a popular way to call long distance. These convert analogue voice signal into digital data and then back into analogue when they reach the receiving phone.

50 years back, who would have thought that advance in technology would bring us to this point? Gone are the days of trunk calls and telegrams, and here is the age of instant messaging and free VoIP calls, wherever you are, and whenever you wish!
