User Interfaces
Two ways to customize configurations of your SIP-T23P/G 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 LED status. The statuses of the power indicator LED and BLF key
LED are configurable via web user interface. You can also customize the BLF key LED status and
BLF key behavior. For more information, contact your system administrator.
