Configuration of Grandstream IPPhone

To access the IPPhone Web GUI:

2. Make sure the phone is turned on and shows its IP address. You may check the IP address on LCD.

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 should 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 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,. 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.

• When changing any settings, always SUBMIT them by pressing the SAVE button on the bottom of the
  page. After submitting the changes in all the Web GUI pages, reboot the phone to have the changes
  take effect if necessary. All the options under Basic Setting and Account Setting, and most of the options under Advanced Settings do not require a reboot after submitting the changes. Under Advanced Setting, the parameters on network configuration require a reboot after the update.
