Telephone connected to FRITZ!Box is dead

When you pick up the handset of a telephone connected to an analog extension of the FRITZ!Box, it does not make a sound (for example a dial tone or busy signal). The telephone is "dead".

Simply proceed as described below. After each measure, check whether the problem is solved.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Plugging the FRITZ!Box in

  1. Plug the FRITZ!Box into a power outlet where other devices work.

2 Installing the latest FRITZ!OS for the FRITZ!Box

  1. Install the latest FRITZ!OS on the FRITZ!Box.

3 Setting up an analog telephone

Only one FON socket can be used

The "FON" socket has two options for connecting devices: An RJ11 socket and a TAE socket. You can only use one connection option at a time:

Example:
If you connected a telephone to the RJ11 socket, you cannot connect a device (for example a fax machine, answering machine) to the TAE socket.

  1. If you connected devices to both of the sockets for the same extension, disconnect one of the devices from the FRITZ!Box.

Testing a different analog telephone

  1. Disconnect the telephone from the FRITZ!Box.
  2. Connect a different telephone to the same socket on the FRITZ!Box.
  3. If you hear a sound, then the first telephone is defective or the telephone cable is damaged or incorrectly wired. Test a different cable or contact the manufacturer of the telephone.
    • If you do not hear a sound, check whether the plug of the telephone is correctly wired. The two inner pins carry the analog signal of the RJ11 socket "FON" on the back of the FRITZ!Box.

4 Restarting the FRITZ!Box

  1. Click "System" in the FRITZ!Box user interface.
  2. Click "Backup" in the "System" menu.
  3. Click on the "Restart" tab.
  4. Click the "Restart" button.
