Simply proceed as described below. After each measure, check whether the issue persists.

  7. Click "Apply" to save your settings.

4 Selecting the correct line type

The line type you must select when configuring your landline number(s) depends on how the FRITZ!Box is connected to the telephone line and not the number of available numbers. For example, if you have an ISDN line with one number, you must select the line type "multiple landline numbers (ISDN line)":

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Telephone Numbers" in the "Telephony" menu.
  3. Click the "New Telephone Number" button.
  4. Enable the option "Landline number" and click "Next".
  5. Select the type of landline and click "Next".

    Important:You will only be asked to select the type of landline (analog or ISDN line) when you configure the first landline number. If you would like to change the type of landline later, you must first delete all of the landline numbers you entered.

  6. Enter your landline number or ISDN telephone numbers (MSNs) and click "Next".

5 Setting up FRITZ!App Fon

Defining telephone numbers for FRITZ!App Fon

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Telephony Devices" in the "Telephony" menu.
  3. Click the button (Edit) for FRITZ!App Fon. When it was installed, FRITZ!App Fon was automatically configured with the telephone's device name on the "LAN/WLAN" port in the FRITZ!Box.
  4. From the drop-down list "Outgoing Calls", select the number to be used by FRITZ!App Fon for making calls.
  5. Select the numbers that FRITZ!App Fon should react to when you receive calls.
  6. Click "OK" to save the settings.

Enabling alternative microphone

The following steps are only necessary if the issue occurs when using FRITZ!App Fon with an Android device:

  1. Start FRITZ!App Fon.
  2. Tap "More" and then "Settings".
  3. Tap the menu key on the telephone and then tap "Advanced".
  4. Enable the option "Alternative microphone".

6 Disabling HD telephony

  1. Enter #962*2* on your telephone and press the call key (lift the receiver).
  2. Hang up again after about 3 seconds.

    Note:You can re-enable HD telephony by entering #962*1*.

7 Checking the cabling

Mistakes in the cabling can often be overlooked. Therefore, make sure that the FRITZ!Box is correctly connected to your line:

  • Check the cabling to your landline.

8 Setting your analog telephone to tone dialing

  • Set your telephone to "tone dialing" (DTMF) and not "pulse dialing". You can find information on configuring the device in its manual, or consult its manufacturer directly.

    Note:If you hear a tone when you press a number key, then your telephone is set for "tone dialing". If you hear clicking sounds, it is set for "pulse dialing".

9 Configuring the FRITZ!Box

Reconfiguring your telephone

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Telephony Devices" in the "Telephony" menu.
  3. Delete the telephone that cannot be used to make calls with. To do so, click the corresponding (Delete) button.
  4. Use the Wizard for telephony devices to reconfigure the telephone: To do so, click the "Configure New Device" button and follow the instructions.

    Important:Do not use the Wizard for telephony devices to configure FRITZ!App Fon. FRITZ!App Fon is automatically reconfigured when you close FRITZ!App Fon completely and then restart the app.

Deleting dialing rules

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Call Handling" in the "Telephony" menu.
  3. Click on the "Dialing Rules" tab.
  4. Delete all dialing rules for numbers or number ranges to be dialed from the landline. In the factory settings, two dialing rules are configured for emergency numbers. You can change these rules, but you cannot delete or block them.
  5. If a "Global Carrier Prefix" has been entered on the "Carrier Prefixes" tab, delete it and click "Apply".
  6. Do not enter any new dialing rules until you are able to conduct calls from the landline. If the error occurs again, then you are using an incorrect dialing rule.

10 Checking the landline

  1. Disconnect the FRITZ!Box from the landline.
  2. Connect a telephony device to the same telephone line and check whether it works.
  3. If this telephony device also does not work when connected to the telephone line, contact your telephony provider and have your line checked.

    ATTENTION!You may be charged for checking. Ask your telephony provider about charges in advance!
