Configuration via Web Browser
The GRP261X/GRP2624/GRP2634/GRP2670/GRP2650 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:
1. Connect the computer to the same network as the phone.
2. Make sure the phone is turned on and shows its IP address. You may check the IP address by pressing and holding the UP
arrow button for 3 seconds when the phone is in an 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.
Notes
The computer must 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 is connected. 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 an IP address of 192.168.40.154, please
enter “http://192.168.40.154” in the address bar of the browser.
