There are two ways to customize specific configurations on your SIP-T28P IP phone:
Using the user interface on the IP phone.
Using the user interface in an internet browser window from 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 instances, it is possible to use both the phone
