Step 2: Check Power and Connections

Ensure that your modem is properly powered and connected:

• Verify that the modem is plugged into a working electrical outlet.
• Check that all cables are securely connected; this includes the power supply, network cable, and phone line.
• If using a power strip, try connecting directly to the wall outlet to rule out power strip issues.

Step 3: Restart the Modem

Restart your FXS modem to reset the system:

• Check if the modem is registering the phone lines correctly.

Step 5: Test Voice Quality

To test the voice quality:

• Make a test call to check the clarity and any delays.
• If issues persist, consider changing the codec settings in the modem’s interface for better compatibility.

Step 6: Update Firmware

Always run the latest firmware for optimal performance:

• Check the manufacturer's website for any available firmware updates.
• Follow the instructions to download and install the latest firmware version.

Step 7: Check for Interferences

Ensure that there are no electronic devices causing interference:

• Keep the modem away from microwaves, wireless routers, and heavy-duty appliances.
• Try moving to a different location to see if the signal improves.

Step 8: Inspect for Hardware Faults

If problems continue despite following all steps:

• Examine the modem for any signs of physical damage.
• If possible, test with another power adapter or phone line to see if the issue persists.

Step 9: Contact Technical Support
