Making Calls General Information
LCR and its application in the
OpenCom 100 correspondingly. Ask
your system administrator for the
configuration applicable to you.
Please note: Baby call and exter-
nal call forwarding are not automat-
ically routed via preferred connec-
tions. In this case, if you do not wish
to use the standard network opera-
tor, you can key in the appropriate
operator’s code digits before enter-
ing the call number.
Transmission of Call
Numbers
In ISDN there are different features
which allow or prevent the transmis-
sion of call numbers between the
calling and called subscribers.
CLIP feature
CLIP is an abbreviation for “Calling
Line Identification Presentation”.
The caller’s call number (if transmit-
ted) is displayed. If this call number
is also stored in the OpenCom 100
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 been 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.
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 as-
sumes that the network provider
transmits this information with the
connection. If the caller's call
number is listed in the
OpenCom 100 telephone book, then
this (local) entry is displayed in pref-
erence.
CLIR feature
CLIR is an abbreviation for “Calling
Line Identification Restriction”. Be-
fore dialling a call number, you can
decide from case to case if you wish
to prevent your call number from be-
ing displayed to the called sub-
scriber. To do this, select Suppress
number (see also “Selection” Menu
in the Idle State starting on page 31).
If this feature is not provided, your
call number will always or never be
displayed, depending on the system
setting. Consult your system ad-
ministrator for more information.
