Adjust the internal number on a Grandstream

Adjust the internal number on a Grandstream


When you change the internal number of a VoIP account on, the internal number on the display of your device does not change. This is because the display of the number on your device is independent of the data in Freedom.

Change internal number in Freedom
  • Go to Freedom.
  • Go to Admin.
  • Click on VoIP account.
  • Choose the VoIP account for which you want to change the internal number (In this example, 201/Bet Weter).

  • Here you can adjust the internal number, for example, from 201 to 208.

  • Click on Save.

The change of the internal number is not yet reflected on your device. To update this on your device, you need to log in to the web interface of the device. You can access the web interface by entering the IP address of your device in your web browser. Instructions on how to find this can be found for each device below.
