Make calls with your smartphone via the FRITZBox

If you want to use your smartphone to make calls to the mobile or fixed network via the Fritzbox, you can do this using the free "Fritz! AppFon" application. We'll show you how it's done.

Call with "Fritz! AppFon" from your iPhone or Android smartphone via the fixed network

The app can only be used as long as you are connected to your home WiFi network. If you are outside this range, the app will no longer work.

1. Download "Fritz! AppFon" for iOS or Android.
2. Connect your device to the WiFi and start the app. You will now be asked for the password for the Fritzbox. If you enter this, your cell phone is automatically set up as a new telephony device in the Fritzbox.
3. Now it can start. You can dial any number from the start screen and call using the green button. The connection is then established via the Fritzbox, you are now making calls via the fixed network and not via the mobile network.

Test judgment and other functions of the "Fritz! FonApp"

• At the top of the app you will see the items "Call list", "Phone book" and "More". You can access both your iPhone contacts and your Fritzbox contacts via the phone book.
• The "More" item takes you to the Fritzbox web interface. There you can check the WiFi connection, export your iPhone contacts to the Fritzbox or make other settings. In the settings you can change your ringtone or suppress your phone number.
• The conversation quality was completely okay in the test. There was hardly any difference to a conversation with the same device via the cellular network.
• Even if your mobile phone is in standby mode or you are using another app, calls are reported and can be answered. Only Bluetooth devices for making calls are currently not supported.

If you want to use your smartphone to make phone calls at home, but don't want to pay money for it, "Fritz! AppFon" is the right choice. A Fritzbox is of course a prerequisite for this.

A simple reset can often help with problems with your internet connection. You can read how to reset your Fritzbox in this practical tip.
