Callers do not hear busy signal when a call is already being conducted via FRITZ!Box

Callers hear a ringing tone instead of a busy signal if a telephone call is already being conducted over the FRITZ!Box. The caller therefore assumes that the line is free.

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

1 Configuring the FRITZ!Box

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Telephony Devices" in the "Telephony" menu.
  3. Click the (Edit) button for the respective telephone.
  4. Click on the "Telephony Device Features" tab.
  5. Enable the option "Call rejection on busy (busy on busy)".
  6. Disable the option "Call waiting".
  7. Click "Apply" to save the settings.

2 Function not supported by telephones connected to Mesh Repeaters

The "Busy on busy" function is not supported when making calls with telephones connected to a Mesh Repeater. If you are using a FRITZ!Fon connected to a Mesh Repeater to make a call, it is therefore not possible to give another caller a busy signal.
