What do I need to use VoIP ?

VoIP requires an Internet connection, as it runs over the IP network. It can be as basic as a dial-up service, but the faster your connection, the better the call quality is. You'd need a high-speed broadband connection to make calls and surf the Internet at the same time.

You'll also need VoIP software or hardware. Skype, for example is one of the more popular VoIP programs. With such software, you use the computer's built-in microphone and speakers, or a headset to communicate, so there is no need for an actual phone for this version of VoIP service.

To convert a regular home phone to a VoIP dialer, an adapter is necessary. In this scenario, the VoIP software is available preinstalled in a separate piece of hardware known as an analog telephone adapter, which is placed between your home phone and the broadband modem.

The cost of these adapters is dropping rapidly. Most are priced well below $100, and in many cases they are simply given to customers who buy VoIP service.
