OVERVIEW OF FUNCTIONS

CONFIGURATION VIA WEB BROWSER
GXP1620/1625/1628 embedded Web server responds to HTTP/HTTPS GET/POST requests. Embedded
HTML pages allow a user to configure the IP phone through a Web browser such as Google Chrome,
Mozilla Firefox and Microsoft’s IE.
To access the Web GUI:

2. Make sure the phone is turned on and shows its IP address. You may check the IP address by
pressing Up arrow button when phone is at idle state;
3. Open a Web browser on your computer;
4. Enter the phone’s IP address in the address bar of the browser;
5. Enter the administrator’s login and password to access the Web Configuration Menu

The computer has to be connected to the same sub-network as the phone. This can be easily done by
connecting the computer to the same hub or switch as the phone connected to. In absence of a
hub/switch (or free ports on the hub/switch), please connect the computer directly to the PC port on
the back of the phone;
If the phone is properly connected to a working Internet connection, the IP address of the phone will
display in MENU->Status->Network Status. This address has the format: xxx.xxx.xxx.xxx, where xxx
stands for a number from 0-255. Users will need this number to access the Web GUI. For example, if
the phone has IP address 192.168.40.154, please enter "http://192.168.40.154" in the address bar of
the browser;
