GUI Config Tool Settings
The GUI config tool is an online tool designed to customize the configuration for devices. Here is the link
to the GUI config tool:
http://tools.grandstream.com:8081
From there, the administrator can build a customized file to remove access for certain apps and task bar
features. The tool would generate a file “gxv3370cust” which should be uploaded to a HTTP/TFTP server.
Then the user needs to configure the server address as GUI Customization File URL under web UI →
Maintenance → Upgrade → Config File to download the file to GXV3370. For more details, please refer to
