[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 7.56 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 7.56 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.

####New features for Mesh

General information on Mesh is presented at en.avm.de/mesh-networking.

Enabling the Mesh Function

To check whether a FRITZ! product is enabled for Mesh, see the Mesh Overview of the FRITZ!Box (the Mesh Master) under "fritz.box -> Home Network -> Mesh". Here the products in the Mesh are designated with a corresponding "Mesh active" symbol.

A FRITZ!WLAN Repeater or FRITZ!Powerline Adapter with FRITZ!OS 6.90 or higher installed can be enabled for Mesh in various ways:

  • If the product has the ex works settings configured and is being connected with the FRITZ!Box for the first time, it will be automatically enabled for Mesh.
  • If the product is already connected, but not enabled for Mesh, it is added to the Mesh by pressing a button on the product to be integrated and a button on the FRITZ!Box. On the FRITZ!Box, use the button that initiates WPS (depending on the model, press the "Connect" or "WPS" button briefly, or the "WLAN/WPS button for 6 seconds)

If you've received the second FRITZ!Box from your internet provider this feature may not work in some cases. Please configurate this FRITZ!Box as a mesh repeater by visit the FRITZ!Box GUI manually. Instructions for configuring a FRITZ!Box connected via wireless LAN as a Mesh Repeater are presented at en.avm.de/mesh-faq

Telephony Mesh and Smart Home Mesh

With FRITZ!OS 7.0, telephony and Smart Home are also compatible with the Mesh.

The connections of cordless telephones and Smart Home products are displayed in the FRITZ!Box Mesh Overview. You can use a second FRITZ!Box as Mesh repeater, and use telephones registered with the second FRITZ!Box with the numbers assigned in the first FRITZ!Box, the "Mesh Master".

Configuring a second FRITZ!Box as a Mesh repeater with the press of a button


  • Your existing FRITZ!Box supports Mesh (FRITZ!OS 6.90 or higher). This box is the Mesh Master.
  • The FRITZ!Box to be deployed as a Mesh repeater has been updated to FRITZ!OS 7.0 and you have restored its settings ex works. This box is to become the Mesh repeater.

Here's how:

  • Connect the LAN1 port of the Mesh repeater with the Master using a LAN cable
  • Initiate the Connect function on both boxes (7590: press the "Connect" button briefly; 7490: press and hold down the WLAN/WPS button for 6 seconds)

After the connection procedure is concluded, the second FRITZ!Box is ready for operation as a Mesh repeater. (It operates in "IP client" mode and, as a Mesh repeater, adopts the wireless LAN settings and other important settings from the FRITZ!Box).

Please note that this function can be used only if the second FRITZ!Box is permanently connected with the first box by LAN cable.

Instructions for configuring a FRITZ!Box connected via wireless LAN as a Mesh repeater are presented at en.avm.de/mesh-faq

Transmit the telephone numbers of a Mesh Master to another FRITZ!Box in the home network

Once you have added an additional FRITZ!Box to the Mesh, you can configure it so that all telephone numbers are available on each FRITZ!Box. If your FRITZ!Box is connected with a landline, you can use the telephones connected to the second FRITZ!Box to make calls over the internet as well as on the landline. If the latest FRITZ!OS 7.0 is installed on both FRITZ!Boxes, the telephone numbers are transferred automatically in the Mesh once the "Telephony in the Mesh" option is enabled.

If the new FRITZ!Box is already part of the Mesh, or if you have already set up telephone numbers there, these telephone numbers must be deleted and one of the two FRITZ!Boxes must be restarted.

Then the new FRITZ!Box must be enabled for "Telephony in the Mesh". To do so proceed as follows:

  • Click on "Home Network" in the user interface of the Mesh Master.
  • Click on "Mesh" in the "Home Network" menu.
  • Click on the "Mesh Settings" tab.
  • In the "Use Telephony in the Mesh" section, click on the "Enable" link next to the Mesh repeater in question and then confirm this operation on the Mesh Master as well, if prompted to do so.

The telephone numbers are now distributed in the Mesh and can be assigned to your telephones and other terminal equipment for telephony (for instance, answering machines) on the FRITZ!Box.

Note: Telephony Mesh is not the same thing as DECT repeating, which requires the support of special hardware on the FRITZ!Box deployed as the Mesh Master. If you would like to use DECT repeating, you can purchase the FRITZ!DECT Repeater 100 from an electronics retailer.

Display of 802.11k and 802.11v support on wireless devices

FRITZ!OS now displays wireless devices that support the wireless standards 802.11k and 802.11v directly in the user interface. Both standards are already widespread for wireless devices and are important prerequisites for the further development of Mesh WiFi for the fastest, lowest-interference, and most convenient control of wireless devices in Mesh environments To find out whether your wireless devices offer support for the 11k and/or 11v standards, see the "Properties" under the Wireless / Radio Network menu, or use the "Edit" function to display the properties of each wireless device.

####Additional Innovations in FRITZ!OS 7.0

What's new for the FRITZ! Hotspot

The new FRITZ!OS 7.0 vmakes setting up and using the FRITZ! Hotspot even easier. It's now even easier for users to choose whether the wireless guest access should be provided as an open hotspot, or encrypted as a private hotspot. If an open hotspot is chosen, the guests do not need to enter a security key. Caf\E9s, doctor's offices and small businesses, as well as all FRITZ!Box users, can provide their customers and visitors an easy-to-use internet access that complies with the current legal regulations. Whether it's private or public hotspot, guests cannot access the home network, but surf using a second wireless LAN provided by the FRITZ!Box.

Secure and Complete Control

The operator of the hotspot can decide which applications can be used in the guest network and which are prohibited. Daily email messages notify the operator of the hotspot about which devices were registered in the radio network and when. Another advantage is the option to reserve bandwidth. This options allows you to specify how much of the data rate is reserved for their own wireless LAN and how much is available to their guests.

Individual & Convenient

The Welcome page of the FRITZ! Hotspot offers additional convenience. Caf\E9s or businesses can greet their guests with a short welcome text, photo or logo. If desired, the guests can also be requested to consent to the terms of use for the hotspot. The hotspot is also available in locations where FRITZ!WLAN Repeaters or powerline devices supporting WiFi provide for better coverage.

Increased speed when using USB storage media with NTFS data systems

If you're using USB sticks or flash drives on your FRITZ!Box that are formatted with the data system NTFS, you can benefit from increased speed during transmission. You don't have to do anything - just continue to use the existing USB storage media as before. To check what data system is used, go to Home Network -> USB Storage Media in the FRITZ!Box user interface.

New security feature in the wireless LAN: "Protected Management Frames (PMF)"

FRITZ!OS now supports additional security during registration of devices with the wireless LAN. "Protected Management Frames" ("PMF" for short) offer additional protection for the wireless connection during the setup phase. PMF is standardized according to IEEE 802.11w-2009 and is automatically offered to or negotiated with wireless devices that support this technology. The new feature is available in the user interface under Wireless > Security > Additional Security Settings.

Support for Telekom SIP Trunking

With FRITZ!OS AVM 7.0 provides support for the SIP trunking technology from Deutsche Telekom. For a few months now, Deutsche Telekom has been offering its business clients a SIP Trunk standard, making it easy to switch from ISDN to IP-based ports. The FRITZ!Box supports up to 20 direct inward dialing (DID) numbers for telephones connected directly to the FRITZ!Box. If a user's phone tariff contains more than 20 direct inward dialing numbers, these can be used with an ISDN PBX (Private Branch Exchange) for the system connection via the FRITZ!Box's internal S0 interface. With FRITZ!OS 7.0, the FRITZ!Box supports the "Deutschland LAN SIP Trunk" and "Deutschland LAN SIP Trunk Pooling" tariffs.

Detailed configuration instructions are presented in the following guide:


MyFRITZ! access to your FRITZ!Box via internet now without security messages in the browser

When you access the user interface of your FRITZ!Box from the internet, a security warning may be displayed in the browser. The new FRITZ!OS version enables your FRITZ!Box to receive a SSL certificate for your MyFRITZ! address from the organization letsencrypt.org. Browser access via the MyFRITZ! address to the interface of FRITZ!Box is no longer accompanied by a security warning, since most browsers trust the certificates from letsencrypt.org.

Proceed as follows:

  1. First you need to register your FRITZ!Box with MyFRITZ! (myfritz.net).
  2. Under "Internet / MyFRITZ! Account", enable the "Let's encrypt" optLet's Encryption.
  3. Confirm by clicking "Apply" and wait for the status "Certificate issued successfully".

Your FRITZ!Box has the certificate created for your MyFRITZ! address and uses it for browser access to this address, for example when you access your FRITZ!Box via your account on https://myfritz.net.

It's also possible to send links for FRITZ!NAS file sharing (for example photos) to third parties, who'll have access without annoying certificate warnings. This way, FRITZ!NAS becomes an even greater alternative to cloud storage services.

Note: To receive the certificate, the TCP port 443 of your FRITZ!Box is open for a few minutes. The certificate is currently valid for 60 days and is then renewed by the FRITZ!Box. HTTPS access to your FRITZ!Box via public or local IP address, "fritz.box" in the home network or over a DynDNS provider do not use the certificate from letsencrypt. MyFRITZ!App: After activation of the Let's Encrypt certificate in the FRITZ!Box, the MyFRITZ!App notifies you once about the change of the certificate fingerprint. Select "trust" to continue using the new certificate.

Option for assessing and, if necessary, remedying detected interference with VDSL from Powerline

In the Internet / DSL Information / Interference Resistance menu of the FRITZ!Box, any interference with VDSL that may have been caused by FRITZ!Powerline can be minimized. This process of checking and adjusting can take up to ten minutes. During this time, the load on the powerline connection may affect the network quality and internet connection. This procedure can be repeated to optimize the interaction of VDSL with a high-performance powerline installation step by step, and the adjustmented settings can be returned to their original configuration.

This option is available only if VDSL interference was detected that could have been caused by a FRITZ!Powerline product.

Support for DECT ULE/HAN FUN

DECT-ULE/HAN-FUN is a manufacturer-independent standard for Smart Home devices.

The following sensors passed testing with FRITZ!OS 7.0 to confirm that they work with HAN-FUN:

  • SmartHome wall switches (https://www.smarthome.de/geraete/telekom-smarthome-wandtaster)
  • SmartHome door/window sensor (https://www.smarthome.de/geraete/eurotronic-smarthome-tuer-fensterkontakt-optisch)
  • SmartHome motion detector (https://www.smarthome.de/geraete/telekom-smarthome-bewegungsmelder-innen) Please note: The HAN-FUN devices are not supported by DECT repeaters. Other types of sensors can also be used as long as their manufacturers have declared them to be compatible with DECT-ULE/HAN-FUN. Actuators from the Telekom SmartHome product range are not supported at this time (e.g., InDoor/OutDoor adapter plugs, sirens).

Used in combination with a FRITZ!Box and the FRITZ!DECT 200/210 smart plug, they can be used to realize the following scenarios:

  • Press wall switch => Outlet is switched => Light on/off
  • Motion sensor triggered => Light on in the home/garage/yard
  • Window sensor open/closed switches FRITZ!DECT 200 => connected humidifier / air purifier switches off/on Please note during installation: The Telekom app cannot be used to install SmartHome devices to be deployed with a FRITZ!Box. The HAN-FUN devices are connected (paired) with the FRITZ!Box via the DECT button. In addition to the AVM Smart Home devices, a maximum of ten HAN-FUN devices can be registered with a FRITZ!Box.
    After successful DECT pairing, the new devices are listed in the FRITZ!Box user interface (Home Network => Smart Home) as "HAN-FUN function xxx" and their properties can be configured accordingly.

If the firmware version 4.01 is installed on your Speedphone 11, perform the following steps:

  1. Register the Speedphone 11 with the FRITZ!Box according to these instructions, during which the expanded security functions of the FRITZ!Box will be disabled briefly: https://avm.de/service/fritzbox/fritzbox-7590/wissensdatenbank/publication/show/3288_Speedphone-nach-Neustart-der-FRITZ-Box-abgemeldet/
  2. If a new Speedphone firmware is available for updating, it will be offered automatically. Alterntively, you can perform a manual check via the menu.
  3. Once the firmware has been updated (> version 4.01), the security functions disabled in step one should be reactivated in the FRITZ!Box.
  4. Re-register the Speedphone 11 with the FRITZ!Box.

The Speedphone 11 is now available for telephone services with DECT encryption enabled. The following features were tested successfully:

  • caller ID display
  • caller ID
  • access to the FRITZ!Box address book
  • call list
  • use of the FRITZ!Box answering machine
