About this app

Easy calling with the landline network

Make calls at home conveniently using your smartphone over your landline telephone numbers - anywhere in the Wi-Fi network of your FRITZ!Box. With the FRITZ!App Fon you benefit from the landline rates; for many providers even from flat rate telephony. HD telephony provides for crystal clear voice quality. Thanks to support for Bluetooth headsets you can enjoy complete flexibility for everyday calling and for working from home. The latest technologies mean that the FRITZ!App Fon works invisibly in the background no matter what the battery status.

The FRITZ!App Fon guides you through the easy Configuration. Simply log in by entering your FRITZ!Box password, selecting one of your landline telephone numbers, and them confirm: your smartphone is ready for landline telephony. Once it has been configured, the FRITZ!App Fon makes your smartphone ring immediately for incoming calls, just as if it were a FRITZ!Fon, the intelligent all-rounder for your home network with FRITZ!. Incoming calls ring simultaneously on your telephones and smartphones. You decide which device should pick up the call. If you would like your smartphone to ring only for certain landline telephone numbers, select only these numbers in the settings of FRITZ!App Fon.

The FRITZ!App Fon is the ideal telephony extension for your FRITZ!Box. Be it a handset for the new roommate in your shared apartment, an additional telephone for working from home, or the convenience of the smartphone that's always handy: with the FRITZ!App Fon you always have a practical solution in no time at all. It is easy to use the FRITZ!App Fon on multiple smartphones.

After some struggles with poor audio quality (voice was barely understandable, I restarted, reseted, reinstalled...), it eventually works ! And I absolutely love the ability to make landline call from my mobile phone ! :) Thanks for the new UI, it looks much better :) And thanks for the answer, I have now my phone contacts once only :) Remain the ability to make calls directly from the Android interface (as there is the option to make Skype or WhatsApp call from a contact).

Hello, when the phone book is open in the FRITZ!App Fon, you can select in the menu (three dots on the top right) which phone books should be displayed. If necessary, please send us feedback with log, support data and the ID "#appfid2920". We have noted your wish to use the Android interface.

Stopped ringing on incoming calls, caller only gets busy signal or client unavailable. Tried everything their FAQs suggest to no avail. Now using LINPHONE without any problems instead.
