About This Guide

Thank you for choosing the SIP-T21P/SIP-T21 IP phone, exquisitely designed to provide

business telephony features, such as Call Hold, Call Transfer, Busy Lamp Field, Multicast

Paging and Conference over an IP network. The difference between the SIP-T21P and

SIP-T21 IP phone is that the former supports PoE, while the latter does not.

This guide provides everything you need to quickly use your new phone. First, verify

with your system administrator that the IP network is ready for phone configuration. Also

be sure to read the Packaging Contents and Regulatory Notices sections in this guide

before you set up and use the SIP-T21P/SIP-T21 IP phone.

If this is your first time using the SIP-T21P/SIP-T21 IP phone, we recommend that you first

refer to the
