Setting up an external fax in the FRITZ!Box

You can use a fax machine connected to an analog extension or the "FON S0" port of your FRITZ!Box to send and receive faxes over the Internet.

Important:Some of the settings described here are only displayed if the advanced view is enabled in the user interface.

1 Enabling fax transmission with T.38

If you would like to use an Internet telephone number for faxing, then you must enable T.38 (fax over IP) for fax transmission in the FRITZ!Box. With T.38, a special network protocol is used for fax transmission instead of fax tones. As a result, transmission is significantly less susceptible to interference:

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Telephone Numbers" in the "Telephony" menu.
  3. Click on the "Line Settings" tab.

    Important:If the "Line Settings" tab is not available, then your cable provider automatically configures the line settings during the configuration procedure. You cannot change these settings later. Your cable provider can provide you with information on the settings.

  4. Enable the option "Fax transmission using T.38" in the "Voice Packets" section.
  5. Click "Apply" to save your settings.

2 Reconfiguring the fax machine

Set up the fax machine in the FRITZ!Box, even if it is connected to the FRITZ!Box via an ISDN PBX:

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Telephony Devices" in the "Telephony" menu.
  3. If the fax machine is already displayed in the list of telephony devices, click the button (delete) for the fax machine.
  4. Reconfigure the fax machine: Click the "Configure New Device" button and follow the instructions.

    Important:If you cannot select the extension the fax machine is connected to when configuring it, then a different telephony device has already been configured for this extension. You must delete this device first.

  5. If the fax machine is connected to the "FON S0" port on the FRITZ!Box, during the configuration procedure you will be shown which telephone numbers to assign to the fax machine. If the fax machine is connected by means of an ISDN PBX, do not assign the telephone numbers to the fax machine. Instead, assign them to the extension of the ISDN PBX that the fax machine is connected to.
