Configuration File Editor gives you the ability to edit custom FreePBX files in the browser that you would normally have to edit through the CLI.
Click on a file name in the list, or click the Add New File button to create a new file.
Some files are not writeable, and therefore cannot be edited. A warning will display above the text field for these types of files.
Edit the file in the text field.
Click the Save button to save your changes.
Click the Apply Config button to apply the changes.
