Well let's begin with what VoIP is. In short, it allows you to make phone calls over the internet using your broadband connection, but has many benefits:

- You can make phone calls from virtually anywhere in the world to anywhere else using your computer.

- Depending on the speed of your connection, you are able to make several calls at the same time.

- If you move home, you are able to keep your same number, even if you move from one side of the world to the other. As you do not have an actual land line, but a converter that has a number assigned, as long as keep the converter with you, you can plug it into any broadband connection and immediately utilize your usual number for making and receiving calls.

Another benefit of VoIP, which many will find useful, and be an attractive feature for many businesses, is the ability to connect to your office phone, whether it be from a hotel or from home. This will enable company personnel to work out of the office, but still have access to all of the office phone system features.

VoIP can also be very cost effective, especially when making long-distance calls. This factor has meant that telephone service providers have to compete with VoIP, in turn ensuring pricing is much more competitive.

At the beginning, the voice quality for those using VoIP was not as good as with a traditional phone line. However the continual technological advancements have meant that the difference in quality is now not as apparent.

So how does it work?

To begin with your voice is converted into bytes so that it can be compressed, split it into packets, and transmitted over the internet. These packets, which contain a collection of information, including the origin, timestamp, and intended destination of the packet, is then converted at the receivers end so that your voice is recognised.
