Wrong outgoing number is used for some calls

Sometimes the outgoing number you configured in the FRITZ!Box for a telephone is not the number it uses for making calls. Individual calls are made using the internet telephone number from a different provider, for example.

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

1 Using a different outgoing number to call back

If you missed a call and want to use the FRITZ!Fon's call list to return the call, the FRITZ!Fon uses the number that to call back. However, you can use a different outgoing number to call back:

  1. Press the "Menu" key on the telephone.
  2. Scroll to "Settings" and press "OK".
  3. "Telephony" > "OK" > "Own telephone no." > "OK"
  4. Select the desired outgoing telephone number.
  5. Click "OK" to save the setting.

Now the telephone number is shown in the display of the telephone and will be used as the outgoing number for the next call.

2 Deleting dialing rules

Dialing rules may have been configured in the FRITZ!Box that force the call to be made using a different outgoing number. Edit or delete all unsuitable 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 of the dialing rules you want to change.
  5. Reconfigure the desired dialing rules.
