This is only necessary if LCR has been
configured for you in the
OpenCom 100. Consult your system
administrator about this.
Least Cost Routing (LCR) can be eval-
uated with call forwarding to exter-
nal numbers, provided your system
administrator has configured LCR
and its application in the
OpenCom 100 correspondingly. Ask
your administrator for the configura-
tion applicable to you.
Note: Baby call and external call
forwarding are not automatically
routed via preferred connections. In
this case, if the network operator
you wish to use is not the default
operator, you must prefix the de-
sired telephone number with the
operator’s code.
Transmission of Call
Numbers
With ISDN there are different fea-
tures which allow or prevent the
transmission of (external) call num-
bers between subscribers.
CLIP feature
CLIP is an abbreviation for “Calling
Line Identification Presentation”.
The caller’s telephone number (if
transmitted) is displayed. If this
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 number is
listed in the OpenCom 100 tele-
phone book, then this – local – entry
is displayed in preference.
CLIR feature
CLIR is an abbreviation for “Calling
Line Identification Restriction”. Be-
fore dialling a telephone number,
you can decide from case to case if
you wish to prevent your telephone
number from being displayed to the
called subscriber. To do this, select
Suppress number (see also “Selec-
tion” Menu in the Idle State starting
on page 31). If this feature is not
provided, your telephone number
will always or never be displayed,
