Callers hear a fax tone

Callers hear a fax tone when they call you. The telephones connected to the FRITZ!Box do not ring or only ring a couple of times and you cannot answer the call.

Cause

  • A fax (external fax machine, integrated fax function of the FRITZ!Box, or fax software) answers the call immediately, so you cannot answer the call with a telephone.

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 Checking the FRITZ!Box's call list

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Calls" in the "Telephony" menu.
  3. Check whether the calls the fax reacted to are marked with a blue or red handset.
  4. If the handset is red, the fax is not connected to the FRITZ!Box. A voice mailbox from your telephony provider may have answered the call. In this case, the problem lies with the telephony provider or the other device.
    • If the handset is blue, the fax function of the FRITZ!Box answered the call; in this case, continue with the next section.

2 Disabling the number for the fax function

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Telephony Devices" in the "Telephony" menu.
  3. Click the (Edit) button for the entry "Fax function".
  4. Disable the telephone number(s) you want to accept calls with.

    Important:You can no longer receive telephone calls with the telephone numbers you select there because the internal fax answers accepts all calls to this number - even telephone calls.

  5. Click "Apply" to save the settings.
