“Calling line identification restriction (CLIR)“ is available and activated
by your network provider.
For some of the ISDN telephones and for the system tele-
phone COMfort 1000/1200/2000 plus, COMfortel 1500/
2500/2500 AB/VoIP 2500 AB and COMfortel DECT 900/900C you
can activate the “Calling line identification restriction (CLIR)“ via an
existing function key or via menu. (see manual of the telephone; per-
haps it is called as “deactivate the identification“ etc.).
If you use an analog telephone as an internal subscriber
phone where a “call without presentation of the calling
number“ can be started, you will be able to use also this comfortable
operation (see manual of the telephone).
Note: Establishing a private call with PIN entry is possible from each
internal telephone with the corresponding exchange line authoriza-
tion. The charges are assigned to the user with help of his user PIN.
