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.
1 Plugging the FRITZ!Box in
- Plug the FRITZ!Box into a power outlet where other devices work.
2 Setting up an analog telephone
Using only one connection option
"FON 1" has two options for connecting devices: A 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 for "FON 1", you cannot connect a device (for example a telephone, answering machine) to the TAE socket.
- 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
- Disconnect the telephone from the FRITZ!Box.
- Connect a different telephone to the same socket on the FRITZ!Box.
- 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 sockets of "FON 1" and "FON 2".
3 Restarting the FRITZ!Box
- Click "System" in the FRITZ!Box user interface.
- Click "Backup" in the "System" menu.
- Click on the "Restart" tab.
- Click the "Restart" button.
