8.2 Calling Line Identification Restriction (CLIR) on a
Call-by-Call Basis
H*14 Z (tel. no.)
For consultation calls:
GR*14 Z (tel. no.)
Activating this function prevents your telephone number from being displayed on
the terminal of the internal or external party for a single call. This procedure is not
necessary:
■ if the “Suppress phone number display permanently” function is set for your
user group or
■ if CLIR is activated for your number in the OpenCom 100 telephone book.
On ISDN telephones you can also activate the calling line identification restriction

acters long.
Please note: Make sure you do not lose your new PIN. Contact your sys-
