Call4tel FXS Gateway Configuration Manual

Setup instructions for connecting and configuring a Call4tel FXS Gateway device with a 3CX phone system, from hardware connection through software provisioning.

  1. Connect the LAN port and power adapter, then flip the power switch — the green PWR indicator lights up.
  2. In the 3CX Management Console, go to Advanced > FXS/DECT and select Add FXS/DECT.
  3. Specify the brand (Call4tel), model, and MAC address, then configure extensions per port.
  4. Synchronize each extension in the FXS Gateway to match its port, then generate and save the XML provisioning file.
  5. Log into the gateway (root/3cx), go to System > Tools > Upload Configuration, and upload the XML file.
  6. Verify port status under System > Status > Port Status, and check registration under System > Status > Register Status.
  7. Confirm registration in the 3CX Management Console's Users tab — ports show green once successfully configured.
