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.
