Two ways to customize configurations of your SIP-T28P IP phone:

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.
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:

available port on the in-line power switch/hub.
Note
If in-line power switch/hub is provided, you don’t need to connect the phone to the power
adapter. Make sure the switch/hub is PoE-compliant.
The phone can also share the network with another network device such as a PC
(personal computer). It is an optional connection.
Important! Do not unplug or remove power to the phone while it is updating firmware
and configurations.
User Guide for the SIP-T28P IP Phone

After your phone is powered on, the system boots up and performs the following steps:
Automatic Phone Initialization
The phone finishes the initialization by loading the saved configuration. The LCD screen
displays “Initializing, Please Wait” during this process.
DHCP (Dynamic Host Configuration Protocol)
The phone attempts to contact a DHCP server in your network to obtain valid network
settings (e.g., IP address, subnet mask, default gateway address and DNS address) by
default.
Note
You can view the system status of your phone via phone user interface or web user
interface.
Available information of phone status includes:
Network status (e.g., IPv4 status, IP mode, MAC address, LAN type, LAN IP and LAN
mask).
Phone status (e.g., device model, hardware version, firmware version, product ID,
MAC address and device certificate status).
Account status (e.g., the register status of SIP accounts).
To view the phone status via phone user interface:
1. Press , or press Menu->Status.
2. Press or to scroll through the list and view the specific information.
To view the phone status via web user interface:
1. Open the web browser on your computer.
If your network does not use DHCP, proceed to Basic Network Settings on page 15.
Getting Started
15
2. Enter the IP address in the browser’s address bar, and then press Enter.
3. Enter the user name (admin) and password (admin) in the login page.
4. Click Confirm to login.
The phone status is displayed on the first page of the web user interface.
If your phone cannot contact a DHCP server for any reason, you need to configure
network settings manually. The IP phone can support either or both IPv4 and IPv6
addresses.
