9. 6. 21 Private calls with PIN
This feature is used to charge private phone calls automatically to private charge 
counters, using the appropriate System Configuration. Users must always enter 
their valid PIN beforehand. They can do so both on one of their own terminals and 
on a third-party terminal on the same communication server or within a PISN.
Detailed Description
The user dials the function code #46, keys in his user number and enters his per-
sonal PIN. This deactivates his external digit barring; the terminal is also unlocked, 
and the user obtains the exchange dial tone. He can then make an external call, 
which is automatically charged to his private charge counter.
Note:
To prevent unauthorized persons from making private calls at other user’ 
expense, all private phone calls must be made with a PIN, even when 
users are using their own terminals. The procedure is the same for both 
locked and unlocked terminals.

Other properties:
• During a call the function can also be made from an enquiry call.
• The called party sees the caller’s user number and not the number of the user 
whose terminal is being used by the caller.
• For reasons of data protection no entry is made in the redial register.
• Unlike with #36 (making calls with your own settings but on a third-party 
phone) you cannot hang up after activating the function and then prefix dial 
within 60 seconds.
• The same PINs are used as for the phone lock.
• Users without their own terminals can be defined as virtual users, and can then 
also use this feature.
