Note
Two ways to customize configurations of your SIP-T19P/SIP-T19 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 19 .
The above introduces the default LED status. The status of the power indicator LED is
configurable via web user interface. For more information, refer to
