Voice over Internet Protocol (VoIP) has quickly emerged as a family of Internet technologies that can deliver voice communications and multimedia sessions in a more efficient manner. With VoIP, voice, fax, SMS and other voice messaging applications are transported through the Internet rather than the public switched telephone network. The three types of VoIP tools that are commonly used include IP Phones, Software VoIP and Mobile and Integrated VoIP.

VoIP equipment refers to all the tangible gear related to VoIP from phones to systems to PBX (News - Alert) hardware to adapters to gateways to headsets.

Some of VoIP equipment has more comprehensive offerings than others, particularly when it comes to VoIP phones. Some VoIP phone systems boast features such as business-class voicemail, desktop video conferencing, small business phone systems and unlimited calling while others offer virtual numbers, call hold, enhanced 911, directory assistance and auto callback.
