VoIP stands for Voice over Internet Protocol. As the term says VoIP is the transmission of voice communication through IP packets and, therefore, through the Internet. VoIP can use accelerating hardware to achieve this purpose and can also be used in a PC environment.

VOIP is a category of hardware and software that enables people to use the Internet as the transmission medium for telephone calls. For users who have free, or fixed-price Internet access, Internet telephony software essentially provides free telephone calls anywhere in the world.

If you're wondering whether this is something that can just replace your standard home telephone service, the answer is that many are doing just that!
