Understanding the Voice Over Internet Protocol

There are many information about Voice over Internet Protocol that are, frankly, hard to understand, especially to the lay man. So I've decided to make intensive research and try to understand the concept in a way that I can explain it to anybody.

The first thing we have to know is what exactly is VoIP? Basically, VoIP stands for Voice over Internet Protocol. It can be better understood as phone services thru the Internet. To broaden it, VoIP is getting almost all the services that the traditional phone offers, but cheaper and more flexible. All that it requires is an excellent broad band internet connection and you're ready to go.

You might be wondering how VoIP works. It works by making the analogue signal into digital format via converting them into smaller parts or packets that is then transmitted over to the internet. From the internet, the packets are then re-assembled to bring it back to its original analogue signal. The whole process is made possible by "compression/decompression" or technically speaking, Codec. Codec is the process of breaking down and putting together large files in order for it to be transmitted thru a series of networks.

In other words, the voice (signal) is broken down to smaller signals so that it can be transmitted to a series of networks via the internet; then the process is reversed wherein the smaller signals are then rejoined to form the original signal that can be received by the other line.

There are 3 modems in which a VoIP can be received. An ATA or Analog Telephone Adapter is like the traditional Telephone that uses a telephone jack and is fixed in one location; the difference is that it uses the Internet in which the ATA is connected to.

A VoIP Phone is another way to receive information, but the difference lies in the fact that it does not need a computer in order to function. A VoIP phone needs only a direct link to an IP network or Internet Protocol such as a Wi-Fi connection.

Lastly, you can also use a soft phone; this service is possible with the help of a Computer and software that is usually provided for by VoIP providers. With the use of a soft phone, one can make calls from computer to phone, Phone to computer, or computer to computer.

What are the advantages of VoIP over the Traditional phone? The best thing about using VoIP is that it is very affordable. Some providers offer unlimited calls, either local or international, at a very low rate, which is usually offered through monthly plans, compared to the Traditional Phone that charges consumers per long distance call added to its usual monthly charge. Another great feature of VoIP is its flexibility and accessibility, whether you are a stay at home mom or a businessman that travels a lot, VoIP is perfect for you, all you need is a steady internet connection.

One major disadvantage lies also to the fact that it is powered by the internet wherein IP traffic is a possibility. If traffic is extensive and your network cannot handle it as fast as it should, information transmitted can take awhile to arrive.

So before choosing to use VoIP, make sure that the service it provides fit your lifestyle.
