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 of your computer, enter the IP address into the address bar (e.g., "http://192.168.0.10" or
"192.168.0.10"), and then press the Enter.
3. Enter the user name (default: admin) and password (default: admin) in the login page and click Login.
Network Settings: Click on Network->Basic->IPv4 Config
You can configure the network settings 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 your phone cannot contact a DHCP server for any reason, you need to configure the IP address, subnet
mask, gateway address, primary DNS address and secondary DNS address for the phone manually.
Note: The IP phone also supports IPv6, but IPv6 is disabled by default.
The wrong network settings may result in inaccessibility of your phone and may have an impact on the network
performance. Contact your system administrator for more information.
