How VoIP works? VoIP converts the voice signal from your telephone into a digital signal that travels over the Internet. If you are calling a regular telephone number, the signal is then converted back at the other end. You can make a VoIP call from a computer, a special VoIP phone, or a traditional phone using an adapter. In addition, new 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.

Advantages of VoIP: VoIP offers features and services that may not be available with your traditional telephone services. If you use VoIP, you can decide whether to pay the cost of keeping your regular landline telephone service. You can also use your computer and VoIP service at the same time. Assuming you have an Internet connection and the necessary equipment, you can also take your VoIP service with you when you travel.
