Voice Over Internet Protocol (VoIP)

Voice over Internet Protocol (VoIP) allows you to make telephone calls using an Internet connection instead of a regular telephone line. Some VoIP services may allow you only to call other people using the same service, but others may allow you to call any telephone number - including local, long distance, mobile, and international numbers.
Equipment Required
First you need an Internet connection, and, for many types of VoIP calls, you need a 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 does not need any special equipment, just a telephone.

Using VoIP Service
If you use a VoIP telephone or regular telephone with an adaptor, you place and receive calls much like 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 preprogrammed name and number. You will then hear a ring just like any other call. Computer-based VoIP services have a variety of ways for notifying you that you have an incoming call.
Some Advantages of VoIP
VoIP may offer features and services that are not available with more 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. Assuming you have an Internet connection and the necessary equipment, you can also take your VoIP service with you when you travel.
Considerations for Using VoIP
If you’re considering replacing your traditional telephone service with VoIP, be aware that:
i) Some VoIP service providers may have limitations to their special service.
ii) Some VoIP services don’t work during power outages and the service provider may not offer backup power.
iii) VoIP providers may or may not offer directory assistance/white page listings.
Difference Between Making a Local Call and a Long Distance Call
Some VoIP providers do not charge for calls to other subscribers to the service. Some VoIP providers charge for a long distance call to a number outside your calling area, similar to existing, traditional wireline telephone service. Other VoIP providers permit you to call anywhere at a flat rate for a fixed number of minutes. Your VoIP provider may permit 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, however, may incur long distance charges.
These factors may change with new developments in VoIP technology. You should always check with potential VoIP service providers to confirm any limitations to their service.
