How It Works
In order to use VoIP, you need a high-speed Internet connection such as broadband Internet connection.The simplest way is through the use of a phone adapter called an ATA (analog telephone adaptor). The ATA allows you to connect a standard phone to your Internet connection for use with VoIP. The ATA is an analog-to-digital converter. It takes the analog signal from your traditional phone and converts it into digital data for transmission over the Internet. You simply use the ATA out of the box, plug the cable from your phone that would normally go in the wall socket into the ATA, and you're ready to make VoIP calls.
