Configuring Your Phone

Configuring via web user interface
Accessing the web user interface:
1. Press the OK key when the phone is idle to get the IP address of the phone.
2. Open the web browser on your computer, enter the IP address into the address bar (e.g.,
"http://192.168.0.10" or "192.168.0.10") and press Enter.
3. Enter the user name (default: admin) and password (default: admin) in the login page and
click Confirm.
Note: Please locate your computer in the same network segment of the IP phone (192.168.0.X) to access
the web user interface. Contact your system administrator for more information.
Network Settings: Click on Network->Basic->IPv4 Config
You can configure the network in the following ways:
DHCP: By default, the phone attempts to contact a DHCP server in your network to obtain
its valid network settings, e.g., IP address, subnet mask, gateway address and DNS
address.
Static IP Address: If the phone cannot contact a DHCP server for any reason, you need
to configure IP address, subnet mask, gateway address, primary DNS
address and secondary DNS address for the phone manually.
PPPoE: If you are using an xDSL modem, you can connect your phone to the Internet via
PPPoE mode. Contact the ITSP for the user name and password.
Note: The wrong network settings may result in inaccessibility of the phone and may have an impact on
the network performance. Contact your system administrator for more information.
