FRITZ!Box 7430 Service - Knowledge Base
Telephone does not ring when configuring it in the user interface
When you configure a telephone under "Telephony > Telephony Devices > Configure New Device" in the user interface, the FRITZ!Box checks whether the telephone is connected properly. After you select how the telephone is connected, the question "Is the telephone ringing?" is displayed. However, the telephone does not ring and you cannot continue with the configuration.
Simply proceed as described below. After each measure, check whether the problem is solved.
1 Connecting the telephone directly to the FRITZ!Box
The following steps are only necessary if the telephone is connected to a PBX (telephone system) that is connected to the FRITZ!Box:
- Disconnect the telephone from the PBX and connect it directly to the FRITZ!Box.
If the telephone rings now, the PBX is incorrectly configured. Information on how to configure the PBX can be obtained from the manufacturer.
2 Testing a different telephone
- Disconnect the telephone from the FRITZ!Box and connect a different telephone to the same socket.
- If the second telephone rings, the first telephone or its cable is defective.
