What is VoIP?

Simply put, VoIP or Voice Over Internet Protocol is the transmission of voice traffic over IP-based networks. It is also sometimes referred to as IP Telephony. VoIP has become immensely popular because of the savings an individual can make on long distance calls, especially on international calls. It is cheap, and some are even offering it for free. Savings can range from 60 to 90 percent, depending on your usage.

How can I use VoIP?

There are three ways of using VoIP. The first one is PC to PC, wherein both parties must have their computers turned on to communicate. Second is PC to Phone, where a party must contact a phone through his computer. Last is Phone to Phone.

What do I need to make VoIP calls?

There are three basic things you need to make a free VoIP call: a computer, a decent internet connection, and a headset with a microphone and earpiece. Scour the web once you have those and you can talk to almost anyone around the globe. The down side of this is you can not make a call unless your computer is turned on.

On the other hand, VoIP companies' services will cut down your long distance costs to a fraction plus you can make calls with your computer turned off. Aside from the basic requirements mentioned above, devices will be provided by the company, usually with a fixed price. The following are the most common devices that you will be issued if you sign up for a VoIP service:

1. Analog Telephone Adapter or ATA. This device is commonly referred to as a phone adapter, and is needed to make Phone to PC and Phone to Phone calls.

2. Tellular Device. This is just like a normal phone, but some are packed with useful features that you will not usually see.

3. Router. A router will allow you to share your Internet connection with multiple computers or Internet devices.

What are the features of VoIP?

VoIP has almost all regular phone features. This includes caller ID, voicemail, 3-way calling, fax, call waiting, and many more. Aside from these, there are a number of advanced features that makes communication easier.

An example would be the "Keep Your Number" feature, which allows you to use the same number even if you move. Another feature would be "Unlimited Calls to US or Canada." This feature is popular among individuals outside of the US because of the savings they can get.

What are the disadvantages of VoIP?

Yes VoIP is cheap and rich with features, but it is not perfect. Voice quality is one of the main concerns of VoIP users. Delays, echoes, and weird noises are frequently attributed with VoIP. A good VoIP company, a sufficient broadband connection, and quality hardware will eliminate this problem.

Another down side with VoIP is that it is dependent on your Internet connection. If you have slow or poor connection, voice quality will surely be affected.

Unlike normal phones, VoIP relies on power. You need to plug in your ATA, modem, and other VoIP devices for you to make calls.
