Making a VoIP Call - VoIP equipment - Part 1

Internet phone calls can also be made without a computer. In that case you need some VoIP equipment installed. A broadband Internet connection is still required but it doesn't need to be connected to a computer to take advantage of VoIP. This kind of system works by installing a broadband

modem to a telephone or cable TV line. The modem is attached to a regular telephone with an Analog Telephone Adapter (ATA). These devices are usually provided free of charge when you sign up with a VoIP service provider.

The ATA allows you to connect a traditional analog telephone to a broadband modem - either a DSL modem connected to your traditional phone line or a cable modem which attaches to your cable TV connection and provides the necessary hardware and software to convert your analog voice signal into compressed digital data. Any traditional analog telephone can be plugged into an ATA. You do not even need a computer in the house to use this type of VoIP connection.

Using an ATA for Internet phone calls is transparent. You simply pick up the phone and dial a number just as you would with your regular phone service. Anybody calling your phone number will not be aware that you are using VoIP instead of PSTN (Public Switched Telephone Network). The person receiving the call does not need any special voice over ip equipment and will have no indication that you are not using PSTN.

In Part 2 you can read more about voice over ip equipment.
