About This Guide

This guide is intended for administrators who need to properly configure, customize,

manage, and troubleshoot the IP phone system rather than the end-users. It provides

details on the functionality and configuration of the IP phones.

Many of the features described in this guide involve network settings, which could

affect the IP phone performance in the network. So an understanding of IP networking

and prior knowledge of IP telephony concepts are necessary.
