Creating a New CFG File
If you want to create a new CFG file for your phone, follow these steps:
To create a new CFG file:
1. Create a CFG file for your phone. Ensure the file complies with the guidelines that are listed
in Editing Common CFG File or Editing MAC-Oriented CFG File.
2. Copy configuration parameters from the template configuration files and set the valid
values for them.
3. (Optional.) Specify different parameter values for specific phone groups.
For example:
[T46S] features.dnd_mode = 1
[T48G, T23G] features.dnd_mode = 0
4. Save the changes and close the CFG file.
