Designing a Voice over Ip Telephony Solution

Designing A Voice Over IP Telephony Solution

November 13, 2003

Abstract

When, on March 10, 1876, Alexander Graham Bell uttered the words into a speaker “Watson, come here; I want you.” (Encarta October 2003) to his assistant Thomas Watson, he gave birth to the modern communications revolution, since that time the telephone has become an integral part of modern society. With the advent of the modern computer and computer networks humankind was availed the ability to communicate with both words and data. It is a natural progression of technology that these two modes of communication be joined into one single network thus affording a blending of technologies that will enhance our communication abilities.

The proposed project detailed in this paper has been prepared with the intention of building a fully converged single network to support; data, voice, and video across all of a medium, sized businesses branch locations. To accomplish this I have researched a Cisco AVVID solution to be deployed at the main facility of a midsized company. This document is intended for those technical staff members who will be installing and supporting this network.

The headquarters convergence project will build the base infrastructure and provide the initial deployment of an enterprise wide IP telephony system. This work entails the main location only unless specifically referencing other sites for various reasons
