Transmitting own telephone number
When you make calls, you can automatically transmit your telephone number (caller ID) to the person you are calling. The person you call can then see your telephone number in the display of their telephone.
Requirements
- The FRITZ!Fon must be registered with a FRITZ!Box.
- The feature "caller ID blocking (CLIR) for individual calls" must have been enabled by your telephony provider.
1 Preparations
- Enter #514*0*#91** on the telephone and press the call key (pick up the handset).
- Hang up again after about 3 seconds.
2 Disabling caller ID blocking (CLIR)
- Click "Telephony" in the FRITZ!Box user interface.
- Click "Telephony Devices" in the "Telephony" menu.
- Click the (Edit) button for the respective telephone device.
- Click on the "Telephony Device Features" tab.
- Disable the option "Calling line identification restriction (CLIR)".
- Click "Apply" to save the settings.
If the telephone number is not automatically transmitted when you make calls now, you must have your telephony provider enable the feature "caller ID blocking (CLIR) for individual calls". No further settings in the FRITZ!Box are necessary.
