VoIP phone adapters enable users to use their standard telephones with their VoIP services. VoIP is Voice over Internet Protocol. It is the technology of transmitting audio as data packets over the Internet to a receiving computer, VoIP enabled phone, or a standard telephone. The standard telephone system is known as the PSTN or Public Switched Telephone Network. The very infrastructure of VoIP and PSTN are completely different networks. People have experienced VoIP technology by using a microphone and speakers connected to their computers, but thanks to phone adapters, users can put away the microphones and speak over VoIP with standard telephones.

A simple form of VoIP is used with many Instant Messaging programs. For free, a computer user can download an Instant Messaging program, connect their computer speakers and a microphone, and make a free long distance (or international) call to another pc user. Many Instant Messaging programs are incorporating VoIP services. You can use Yahoo Messenger, AOL, Skype, ICQ, MSN, and Google to make pc-to-pc free phone calls.

Another more advanced form of VoIP is to use a monthly service provider for the handling of all of your telephone needs. A VoIP provider will work much like your traditional telephone service yet you will not need to have your house wired or have phone jacks installed. With a phone adapter you will be able to transform your household phone into a phone that will work with your VoIP service. You can also connect a portable phone to the adapter and have a portable phone that operates on your VoIP service. Your service provider will provide you with the telephony adapter.
