VoIP

From Catherine Roseberry, for About.com

Definition: A technology which uses Internet Protocols for transmissions. VoIP enables users of broadband Internet access to make phone calls to other VoIP users and regular phones.
VoIP provides cost savings over traditional land-line phone long distance and cell phone long distance charges.
VoIP can also be used for voice mail and fax mail applications, reducing the need to print documents or have access to email applications.
VoIP takes advantage of Internet Protocols by using packet networks to transmit voice data.
VoIP services work directly through your computer using a headset or special VoIP phone, while others require a special adapter which is attached to your regular phone.
