Voice over IP: Convenient Than Traditional Phone

As the name suggest (voice over internet protocol) VOIP technology uses internet as a medium to transport phone calls. Why the use of internet is necessary?

Because, if you make a international call using existing PSTN, your call have to pay for using several infrastructure beyond your local telephone infrastructure like undersea telephone cables, satellites and the infrastructure of overseas telephone service providers.

But you can bypass the cost of those infrastructures by only paying a fixed monthly bill to your internet provider and internet connection in cheap or somewhere free all over the world.

Just simple is that, VOIP makes sense in term of economic and infrastructure requirements.
