What is VoIP?
To put it in a nutshell, Voice over Internet Protocol or VoIP is the method that enables you to transmit whatever you say on the phone through internet to another person. These internet phones make use of fiber optic cables that help you stay connected to people all over the world.

The employees of a company might be spread out in different continents but they get to speak with each other using VoIP as a common platform.

How Does VoIP Work?
In the olden days, the telephones used to rely on copper wires to transmit your voice over a long distance. However, this proved to be costly owing to the high cost of installing telephone wires all across the length and breadth of the world.
However, with the advent of the Internet, the use of fibre optics became prevalent all over the world. Fibre optics makes use of optical cables that are made of many wires made of fiberglass that are enmeshed together. They are very durable and can withstand rough wear and tear.
They are also very cheap to make and install making their prices much more competitive than erstwhile copper wires. They are also able to transmit large amounts of data making it possible to accommodate large bandwidths in limited space.
All these advantages make it very likely that normal telephone wires will soon be a thing of the past as they will all be replaced by optical fiber cables. Hence, VoIP is soon going to rule the roost in the field of Internet phone services.
