Note

Two ways to customize configurations of your SIP-T21P/SIP-T21 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, you can use the 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 soft key to access the phone user

interface. The Advanced Settings 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

The above introduces the default LED status. The statuses of the power indicator LED and

BLF key are configurable via web user interface. For more information, refer to
