Blocking your telephone number from being displayed
You can block your telephone number from being displayed when you make a call. That way, the person
you are calling does not see your number in the display of their telephone. This function is called "caller
ID blocking" or "CLIR" (Calling Line Identification Restriction). You can either block your telephone number
(caller ID) for just a specific call or for all of the calls you make.
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.

2. Scroll to "Settings" and press "OK".
3. "Telephony" > "OK" > "Anonymous call" > "OK"
4. Enable the option "Next call".
