Uploading the Call4tel FXS Gateway Template to 3CX

A narrower companion guide to FXS setup, focused specifically on the template upload workflow rather than full gateway configuration.

  1. Download the Call4tel NX-FXS templates ZIP file and extract it.
  2. Change the Call4tel XML file's owner from root to phonesystem.
  3. Upload the renamed file to the correct server directory (Linux or Windows path, depending on your 3CX host).
  4. In 3CX's Advanced menu, select the matching Call4tel device template.
