Phone does not ring when you receive a call

One or more of the phones connected to the FRITZ!Box doesn't ring when someone calls you? ✔ Here's what to do.

One or more of the phones connected to the FRITZ!Box doesn't ring for an incoming call. This happens with some incoming calls, or with all of them. Outgoing calls can be made.

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 Assigning phone numbers to phones

  1. Click on 'Telephony' in the FRITZ!Box user interface.
  2. Click on 'Telephony Devices' in the 'Telephony' menu.
  3. Click on the (Edit) button for the respective phone.
  4. Configure the phone so that it reacts to incoming calls to the desired phone number: Enter the number under 'Outgoing calls' or 'Incoming calls', or enable the 'React to all numbers' option.
  5. Click on 'Apply' to save the settings.

2 Maintaining a permanent internet connection

Calls to your internet phone number can only reach the FRITZ!Box if an internet connection is active. Therefore, configure the FRITZ!Box so that it maintains a permanent internet connection:

  1. Click on 'Internet' in the FRITZ!Box user interface.
  2. Click on 'Account Information' in the 'Internet' menu.
  3. Click on 'Change connection settings'.
  4. Enable the 'Maintain permanently (recommended for flat rates)' option. If the option is not shown, the FRITZ!Box is already permanently connected to the internet.
  5. Click on 'Apply' to save the settings.

3 Reconfiguring the phone number and having it checked

  1. Click on 'Telephony' in the FRITZ!Box user interface.
  2. Click on 'Phone Numbers' in the 'Telephony' menu.
  3. Click on the (Delete) button for the phone number to be reconfigured.
  4. Reconfigure the phone number and select your telephony provider during setup.
  5. If the phone still does not ring for incoming calls, contact your telephony provider to have your phone number checked.

    Important:After the porting of a phone number, it is often possible to make calls with this phone number immediately. In some cases it may take one or two days before incoming calls are signalled.
