Note
Two ways to customize configurations of your SIP-T42G 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.
The above introduces the default power indicator LED status. The status of the power
indicator LED is configurable via web user interface. For more information, refer to
Yealink_Microsoft_Skype_for_Business_Edition_IP_Phones_Administrator_Guide .

User Guide for the SIP-T42G IP Phone

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 35.
Menus are used to access information and configure the phone.
The figure below shows the phone's menus and submenus.

Overview

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 on the phone. Enter the IP address
(e.g., http://192.168.0.10 or 192.168.0.10) in the address bar of the web browser on your
PC. The default administrator user name and password are both “admin”
(case-sensitive).
The main 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:
