About This Guide

	Thank you for choosing the SIP-T20P/SIP-T20 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-T20P and
	SIP-T20 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-T20P/SIP-T20 IP phone.
	If this is your first time using the SIP-T20P/SIP-T20 IP phone, we recommend that you first
	refer to the Quick Installation Guide and Quick Reference Guide, available online:
	http://www.yealink.com/SupportDownloadfiles_detail.aspx?CateId=187&flag=142 .
Note	Shared Line, Busy Lamp Field List, Network Directory and Network Call Log features are
	hidden for IP phones in neutral firmware version, which are designed for BroadWorks
	environment. Please contact your system administrator for more information.

Overview

Two ways to customize configurations of your SIP-T20P/SIP-T20 IP phone:

The user Interface on the IP phone.

The user Interface in a web browser on your PC.

The hardware components keypad and LCD screen constitute the phone user interface , which allows the user to execute all call operation tasks and basic configuration changes directly on the phone. In addition, each phone has a web user interface to access all configuration settings. In many cases, either the phone user interface and/or the web user interface interchangeably. However, in some cases, it is only possible to use one or the other interface to operate the phone and change settings.

You can customize your phone by pressing the MENU key to access the phone user interface. The Advanced option is only accessible to the administrator, and the default administrator password is ―admin‖ (case-sensitive). For more information on customizing your phone with the available options from the phone user interface, refer to Customizing Your Phone on page 17.

In addition to the phone user interface, you can also customize your phone via web user interface. In order to access the web user interface, you need to know the IP address of your new phone. To obtain the IP address, press the OK key on the phone. Enter the IP address (e.g., http://192.168.0.10 or 192.168.0.10) in the address bar of web browser on your PC. The default administrator user name and password are both ―admin‖

(case-sensitive).

The options you can use to customize the IP phone via phone user interface and/or via web user interface are listed in the following table:
