Voice over Internet Protocol(VOIP)

Abstract

Most people are familiar with NetMeeting and other software that let you talk to others over the internet. VOIP is similar. However, it also uses your phone - the interface we’re all familiar with.
Instead of connecting your phone to the wall, you connect it to a box that ‘modem’ along with highspeed/broadband internet. Your modem plugs into modem and now it can ‘talk’ between your phone and the internet.
The VoIP application allows to convert analog voice signals such as telephone calls and faxes into digital IP(internet protocol) packets and distribute these packets across a wide area network. In VoIP technology, a digital signal processor (DSP) segments the voice signals into frames and stores them in packets.
The term “Voice over IP” (VoIP) describes the transport of voice over IP based networks, it is a generic term that covers deployments ranging in complexity from hobbyists using the internet to get free phone calls on a peer to peer basis.
In carrier networks VoIP has been mainly deployed in enterprise networks or as a trunking technology to reduce transport costs in voice backbone networks.
