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:
