About This Guide

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

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

details on the functionality and configuration of IP phones.

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

the IP phone’s performance in the network. So an understanding of IP networking and a

prior knowledge of IP telephony concepts are necessary.

This guide covers SIP-T48G, SIP-T46G, SIP-T42G, SIP-T41P, SIP-T40P, SIP-T29G, SIP-T27P,

SIP-T23P/G, SIP-T21(P) E2, SIP-T19(P) E2 and CP860 IP phones. The following related

documents are available:

Quick Start Guides, which describe how to assemble IP phones and configure the

most basic features available on IP phones.

User Guides, which describe the basic and advanced features available on IP

phones.

Auto Provisioning Guide, which describes how to provision IP phones using the

configuration files.

Description of Configuration Parameters in CFG Files, which describes all

configuration parameters in configuration files.

<y0000000000xx>.cfg and <MAC>.cfg template configuration files.

IP Phones Deployment Guide for BroadSoft UC-One Environments, which describes

how to configure BroadSoft features on the BroadWorks web portal and IP phones.
