Importing Extensions

  1. You can import a new CSV file of extensions at any time. To do this, it is recommended to start with exporting at least one extension created on your PBX so you can see the proper CSV format.
  2. In the CSV file, you can edit the extension configuration, add new entries, and delete fields except for “type”, “username”, “registerpassword”, “loginpassword”. But if you don’t want to configure Registration Password and Login Password, the system will generate the passwords automatically. The last tip, don’t change the spelling of the name of the top row.
  3. Click “Import” button to import extensions by choosing a CSV file from your local computer. Then click “Import” button when done.
