Setting up an IP door intercom system in the FRITZ!Box

You can register an IP door intercom system with the FRITZ!Box and then talk with visitors and open the door when you are away from home if you route the door call to an external telephone number, for example. If the door intercom system has a camera, you can have the image from the door intercom system displayed on a FRITZ!Fon.

Requirements / Restrictions

  • The camera for the door intercom system saves images in JPG/JPEG, PNG or GIF file format. Other file formats, for example MJPG/MJPEG, are not supported.
  • The camera makes the images available via FTP or HTTP. HTTPS is not supported.
  • To show the images, a FRITZ!Fon with color display (FRITZ!Fon MT-F, C4, or newer) must be used.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Connecting the door intercom system

  1. Either use Wi-Fi or a network cable to connect the door intercom system to the home network of the FRITZ!Box (not the guest network).

    Important:You may not use any internal telephone numbers of telephony devices connected to the FRITZ!Box for the bell buttons.

  10. From the drop-down list "Route Doorbells to", select the telephones or telephone number the doorbell should be routed to:

    Important:You can either select one or several internal numbers, or you can select an external telephone number. You cannot combine internal and external numbers.

    • If you want a specific telephone to ring, select the respective telephone.
    • If you want all of the connected telephones (broadcast call) to ring, select "All telephones".
    • If you want an external telephone number (for example another telephone line, mobile telephone) to ring, select "Telephone number" and enter the destination telephone number.
    • If you want several telephones connected to the FRITZ!Box (call group) to ring:

      3. Click "OK".
  11. Click "Next" and then "Apply" to save the settings and on the FRITZ!Box, confirm that the procedure may be executed, if you are asked to do so.

3 Configuring the door intercom system

  2. Click "Telephony Devices" in the "Telephony" menu.
  3. Click the (Edit) button for the door intercom system.
  4. From the drop-down list "Outgoing calls via", select the outgoing call number that should be used if you want to route the doorbell to a mobile telephone or an external line.

  6. If the door intercom system is equipped with a camera or you use an IP camera in your home network, enter the complete web address with the image files in the "Live image" field. This URL must end with the file format of the image (for example image.jpg). The image is then displayed on the FRITZ!Fon when there is a call from the door intercom system.
  7. Click "OK" to save the settings.

4 Entering login information in the IP door intercom system

  1. In the door intercom system, configure an internet telephone number with the login information for the FRITZ!Box.
  2. Enter the username displayed in the FRITZ!Box user interface as the username for the telephone number.
  3. Enter the same password that you entered in the FRITZ!Box user interface.
  4. Enter fritz.box or the IP address of the FRITZ!Box (192.168.178.1 in the factory settings) as the SIP registrar.
  5. Do not enter a STUN server.

5 Notes on the live image displayed by FRITZ!Fon

The FRITZ!Fon only rings three times if you set up the live image function so that video transmission is not disturbed. If you want it to ring longer, add another telephone without live image to the call group. This telephone will continue to signal the call from the door intercom system.

Use the "OK" key to switch between Standard View and zoom, and use the navigation keys to change the area of the image displayed in the zoomed-in view. The selected area is then used for the next call.
