Caller ID is not shown for incoming calls

Caller ID is not shown for incoming calls:

  • When you receive calls, a telephone connected to the FRITZ!Box does not show the caller's telephone number (caller ID), or the caller's telephone number is only shown briefly in its display.
  • A telephone does not show which telephone number the caller has called.

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

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Activating text information in the FRITZ!Box

The following steps are only necessary if you are using a FRITZ!Fon:

  1. Enter #960*2* on your telephone and press the call key (pick up the handset).
  2. Hang up again after about 3 seconds.

    Note:To deactivate text information display again, enter #960*0*.

2 Defining display names in the FRITZ!Box

The following step is only necessary if the telephone shows caller ID, but not the number that the caller called:

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Telephone Numbers" in the "Telephony" menu.
  3. Click the (Edit) button for the respective telephone number.
  4. Enter a name of your choice in the "Display name" field.

    Example:
    You can enter "VOIP_12345", "provider_12345", "office", "private" or "12345" as the display name for the internet telephone number 12345.

  5. Click "Apply" to save the settings.

3 Checking the FRITZ!Box's call list

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Calls" in the "Telephony" menu.
  3. Check whether there any incoming calls (blue or red handset) that show the caller ID.
  4. If caller IDs are displayed, the FRITZ!Box detects the numbers of the callers. The telephone does not display the caller IDs because it does not process the numbers signaled by the callers according to the general specifications. However, the telephone may display caller ID when connected directly to your line, but not when it is connected to the FRITZ!Box.

    Note:CLIP can be used with many cordless telephones, for example with all FRITZ!Fon models and many telephones from the Siemens Gigaset series. However, AVM cannot guarantee that CLIP will work with telephones from other manufacturers.

    • If no caller ID is shown, either your internet telephony provider did not enable CLIP, or the callers do not transmit their caller ID.
