[1] Talking caller ID - FRITZ!Fon learns to speak: New features for FRITZ!Fon

New "Voice" Ringtone

The new "Voice" ringtone announces the name of the caller, if available, or the location the call is coming from along with the telephone number of the caller. The feature is available for incoming calls, but a voice announcement can also be selected for alarms and appointments.

When you get a call, instead of a ringtone the caller's name is announced if their telephone number is in your contacts.

If there is no telephone book entry, the location from which the call is coming is announced, depending on the country, along with the telephone number of the caller.

You'll need to have an active MyFRITZ! account.

This feature can be enabled under "Telephony / Telephony Devices" in the user interface.

Select the FRITZ!Fon handset you want to edit, assign one or more telephone numbers for incoming calls, and then switch to "Ringtones".

Select there the "Voice" ringtone for the corresponding telephone number at the end of the list.

You can configure additional settings under "Voice Ringtone".

For alarms and the appointment calendar you can select the "Voice" ringtone directly on the FRITZ!Fon.

Appointment Calendar

With the new calendar, you can now set up appointments in FRITZ!Fon and create a reminder for them.

You can also be reminded of the appointment with the new "Voice" ringtone.

Note: The new features are available for FRITZ!Fon M2, C4, C5 and C6 with the latest handset firmware.

[2] WireGuard Support for Simple Setup of VPN Connections

WireGuard(R) is a modern, easy to understand, fast, and simple VPN solution.

For most operating systems, there are apps or programs from WireGuard for connecting single devices to a network via WireGuard VPN.

WireGuard is a registered trademark of Jason A. Donenfeld (https://www.wireguard.com).

WireGuard is not compatible with other VPN protocols. Therefore it cannot connect to IPSec, OpenVPN and similar peers.

WireGuard itself does not contain any mechanisms for key distribution. Both parties therefore require the public keys of the respective remote site.

The concept for the FRITZ!Box is that both key pairs can be generated on the FRITZ!Box to set up a connection, and all the necessary dial-in data can be imported on the client side via a file or QR code, e.g. in the WireGuard App.

For your FRITZ!Box to be accessible via WireGuard VPN, you need a MyFRITZ! address your (you'll need to register your FRITZ!Box with MyFRITZ!Net) - or a third-party DynDNS address for your FRITZ!Box.

Please note that the connection configuration - QR code or configuration file - is not permanently stored on the FRITZ!Box (for security reasons). Do not let the QR code or configuration file fall into the hands of unauthorized persons.

[3] Mesh Wi-Fi - More Performance for FRITZ!Box as Mesh Repeater

FRITZ!Box devices that support "Mesh Repeater" operating mode could previously be connected to other FRITZ!Boxes or FRITZ!Repeaters only with one Wi-Fi band (2.4 or 5 GHz) at a time.

With the new FRITZ!OS, it's now also possible to use more than one Wi-Fi band for the Wi-Fi uplink.

This enables higher data throughputs and stability in the Mesh. When updating a Mesh network that's already been set up with an older FRITZ!OS, which consists of one or more FRITZ!Box devices in Mesh Repeater mode, the previously unused Wi-Fi band is connected automatically.

[4] More Operating Convenience in the FRITZ!Box User Interface

The FRITZ!Box user interface has been visually refreshed with the new version.

Particularly noticeable here is the separation of the menu from the left edge of the screen and the width of the displayed pages have been trimmed for better readability.

This has a positive effect on tables and texts, especially when displayed on particularly large screens (resolutions), and at the same time improves the display on smartphones and tablets.

The redesign is based on a new style guide that facilitates the integration of innovative operating concepts.

[5] Automation

Scenes - Create the Perfect Mood for Every Occasion

With scenes you can simultaneously perform different actions in the Smart Home.

For example, with the "Coming Home" scene, all radiator controls can be set to the comfort temperature at the touch of a button, and your LED lights and smart plugs, the Wi-Fi and/or guest Wi-Fi, and the answering machine can all be switched on at the same time.

The preconfigured two scenes "Coming Home" and "Leaving Home" and can be applied directly. They consist of automatically generated templates that can be subsequently turned on and off as required.

With a scene you create yourself, multiple devices can be combined and controlled.

Templates that have already been created can be added and deleted on an individual basis.

Furthermore, individual templates can be created as a simple scene. Settings for devices and/or device groups can be saved and reused with templates.

Scenes can be used via the FRITZ!Box, a FRITZ!Fon, FRITZ!App Smart Home or the FRITZ!DECT 440.

Routines - for Customizable Automations in the Smart Home

Routines enable devices, scenes and templates to be automatically controlled or enabled by an if-then link.

The shortcut consists of a trigger and a condition that must be met for an action to be performed.

In the Configuration Wizard, you can define a device as a trigger, then specify the change in state or an event (condition). Finally, a previously created scene or template (action) is selected, which is activated when the condition is met.

For example, if the humidity measured by the FRITZ!DECT 440 reaches a certain level, the previously configured scene "Ventilation" with a FRITZ!DECT 200 smart plug with a connected humidifier is applied.

[6] Additional Confirmation

After this update, additional confirmation for certain settings and functions can no longer be disabled.

However, if additional confirmation was disabled before the update, this condition remains intact after the update.

AVM recommends always using additional confirmation for reasons of security.

To allow changes to protected settings from on the go, the TOTP standard with one-time passwords can be also used for additional confirmation.

A freely available password manager or a separate app like the Google Authenticator can be used for this.

[7] New wizard transfers all important settings for the internet, telephony, and Wi-Fi network, and connections to Mesh, telephony and Smart Home devices to a new FRITZ!Box.

Please take note of the following tips and requirements:

The Wizard provided in this FRITZ!OS offers assistance if you are using a FRITZ!Box that you would like to replace with another new FRITZ!Box. Any other FRITZ! products connected with your currently used FRITZ!Box, including FRITZ!Repeaters, FRITZ!Fons, FRITZ!DECT Smart Home products, and FRITZ!Apps will also be connected to the new FRITZ!Box.

This new switching function makes it easier to exchange your old FRITZ!Box with another FRITZ!Box, so that

  • the Wi-Fi and home network and all of the connected home network devices will work the same after the switch

  • no settings have to be changed on the devices connected with the FRITZ!Box because of the switch

  • the internet connection and telephony can continue to be used in the same way

  • all important settings on the currently used FRITZ!Box are transferred to the new FRITZ!Box (for instance, for telephony, Smart Home, and MyFRITZ!)

  1. Two steps must be taken to prepare the other, new FRITZ!Box:

    • a current FRITZ!OS version 7.55 or newer. During the course of the wizard you will be prompted to update your new FRITZ!Box if necessary.

    • Set your new FRITZ!Box back to its factory settings , if it was used at all before, and then disconnect it from electrical power.

  2. The currently used FRITZ!Box provides the internet connection on your line and has the latest FRITZ!OS version 7.55 or newer.

  3. If you use any FRITZ!Repeaters: Update their FRITZ!OS.

  4. If you use FRITZ!Fons or FRITZ!DECT Smart Home products, check whether a software update is available and, if so, install it.

  5. If you use FRITZ!Apps for the previously used FRITZ!Box, have your smartphone ready.

  6. You must have physical access to the FRITZ!Box you are currently using, so that you can insert its network cable and press the buttons. The other, new FRITZ!Box should be close at hand. You will also need to connect to electrical power and the internet for the switching procedure.

  7. If you are not only changing the FRITZ!Box model, but also the type of connection (for instance, from DSL to fiber optic), then the other, new connection must be ready for operation.

  8. You must be connected with the homei network of the currently used FRITZ!Box with a notebook or computer (recommended) or by smartphone. Under "Wizards" in the http://fritz.box user interface there is a "Transfer Your Settings to a New FRITZ!Box" link to click. Read the instructions presented there and follow them carefully. The process usually takes around 10 to 30 minutes, depending on the complexity of the home network.
