2.1.15 Transmission of Call Numbers
With ISDN there are different features which allow or prevent the transmission of
(external) call numbers between subscribers.
“CLIP”
“CLIP” is an abbreviation for “Calling Line Identification Presentation”. The caller’s
call number (if transmitted) is displayed by means of the corresponding call key. If
this number is also stored in your telephone book, the caller’s name is displayed.
“CLIP no screening” Feature
Using “CLIP no screening” outgoing connections instead of sending the real call
number of the caller, send another call number. Thus, instead of being shown your
number, the subscriber you have called is shown, for example, a service call
number. The feature “CLIP no screening” must be enabled by the network provider
and activated in the system configuration by the system administrator. When you
receive an external call where the caller indicates a different number than the one
actually being transmitted, your display will show a “?” next to the call number. If
the indicated call number is saved as a phone book entry, as usual, the name will
be shown along with a question mark.
“CNIP” Feature
“CNIP” is an abbreviation for “Calling Name Identification Presentation”. In
addition to the call number, the name configured by the caller is also transmitted
and displayed on the corresponding call key. This assumes that the network pro-
vider transmits this information with the connection. If the caller's number is listed
in the OpenCom 100 / Aastra 800 telephone book, then this
–

–
entry is dis-
played in preference.
“CLIR” Feature
“CLIR” is an abbreviation for “Calling Line Identification Restriction”. Before dialling
a call number, you can decide from case to case if you wish to prevent your call
number from being displayed to the called subscriber. To do this, select
Sup-
press number
from one of the MenuCards described in the next section.
If this feature is not provided, your telephone number will always or never be dis-
played, depending on the system setting. Consult your system administrator for
more information.
