  • FiOS - Echo on the Line Follow these steps if you are hearing an echo on your phone line:

    1. If you are using a cordless phone, turn down the volume and call a local, non-FiOS phone number.
      If you still hear an echo, go to 2.


    2. Unplug any filters that are plugged into any of your phone jacks, then call a local, non-FiOS phone number.
      If you still hear an echo, go to 3.


    3. If your phone has a Voice Enhancement feature, ensure that it is turned off, then call a local, non-FiOS phone number.


    If you still hear an echo, do the following:

    1. Unplug all phones in your house.


    2. Take a standard phone (a phone with a cord, not a cordless or cell phone) to the Optical Network Terminal (ONT) and plug it in.
      If you have never opened the ONT before, refer to test procedure for an ONT for more details.


    3. Call a local, non-FiOS phone number to see if the echo is still there.


    4. From within your home, use the same phone to call the same local, non-FiOS number that you called from the ONT.


    5. If you heard an echo when calling a local, non-FiOS phone from both inside the house and at the ONT, then the problem is mostly being caused by the network.
      You can use the Verizon Troubleshooter to diagnose your telephone's problem and request a repair if an issue is detected.


    6. If you did not hear an echo when calling from the ONT, the problem may be with your phone equipment.
      You can use the Verizon Troubleshooter to diagnose your telephone's problem and request a repair if an issue is detected.
    FiOS Phone Service may not be available in all areas.
