VOIP (Voice Over Internet Protocols)
VoIP converts voice into data and sends the voice packets over the network. These packets get mixed with other voice and data packets and are reassembled into voice by an endpoint device (telephone). The result is a telephone call.
A VoIP system consists of several components. There are the endpoints, also known as telephones. These can be either an IP telephone or a soft-phone residing on a PC. The soft-phone is a program that runs on your PC and performs all of the same functions of a telephone using your multimedia speakers and microphone plus video in some instances.
The role of an IP telephone is identical to that of a traditional telephone. An IP telephone connects directly to a LAN instead of a traditional telephone connection.
The equipment for VoIP varies depending on the application. The exact list of equipment depends on the specific requirements of your business.
