How VoIP Works

Voice over Internet Protocol (VoIP) is a technology for communicating using "Internet protocol". Several VoIP services are available today. Some VoIP services need only a regular phone connection, while others allow you to make telephone calls using an Internet connection. Some VoIP services may allow you only to call other people who are using the same service, while others may allow you to call any telephone number around the world including - local calls , long distance call, wireless, and international telephone numbers.

How VoIP Works

VoIP converts the voice signal from your telephone into a digital signal that can travel over the Internet. If you are calling a regular telephone number, the signal is then converted back at the other end. Depending on the type of VoIP service, you can make a VoIP call from a computer, a special VoIP phone, or a traditional phone. Wireless "hot spots" in public locations such as airports, parks, and cafes allow you to connect to the Internet, and may enable you to use VoIP service wirelessly. If your VoIP service provider assigns you a regular telephone number, then you can receive calls from regular telephones that don't need special equipment.

In order to use VoIP, you may need a high-speed Internet connection such as broadband Internet connection.

Depending on the VoIP service you purchase, you may need a computer, a special VoIP telephone, or a regular telephone with an adapter. If you are calling a regular telephone number, the person you are calling may need any special equipment but just a telephone.

How to Use VoIP Service

If you use a VoIP telephone or regular telephone, you place and receive calls same as you do with regular telephone service. If you use VoIP with your computer, a telephone icon usually appears on your computer screen. Clicking the icon allows you to dial numbers from a pad, or dial a call by clicking on a contact's pre-programmed name and number. You will then hear a ring similar to any other call. Computer-based VoIP services have a variety of ways for notifying you that you have an incoming call.

Some VoIP providers do not charge for calls to other subscribers to the same service. Some VoIP providers charge for a long distance call to a number outside your calling area. Other VoIP providers allow you to call anywhere at a flat rate for a fixed number of minutes. Few VoIP service providers may allow you to select an area code for your VoIP service that is different from the area code in which you live. Calls within your VoIP area code may not be billed as long distance calls. People calling your VoIP area code from another area code may have to pay for long distance charges.

Advantages of using VoIP

VoIP offers features and services that are not available with traditional telephone services. If you use VoIP, you can decide whether to pay the cost of keeping your regular telephone service. You can also use your computer and VoIP service at the same time. You can also take some VoIP services with you when you travel and use them via an Internet connection.
