In simple definition VoIP is a technology enables you to communicate over internet lines, also which it saves money and reduce cost.
In case of using VoIP technology something must be enable to start.
1. You'll need a microphone equipped computer for making calls to adapter unit that VoIP qualified. Or, you may instead like to use your standard telephone.
2. When you hold telephone headset and dial a number overseas, the VoIP adapter understand what you are doing and turns the voice signals you are sending into digital based signals. These are sent overseas through the Internet, instead of sending any phone line.
3. In the other side of world your friend receives your call in the same way by the same device. He will pick up the headset when you call and then VoIP goes to work again. In this time the VoIP system reflects the process and translates the digital like signals back into a standard voice. And when your friend uses their phone, he will hear your voice, that is all.
Did you see? It is really easy over can you imagine, and it doesn't need much of a difference in the experience over than using the telephone. You will do the same thing every time you need to do.
