General Functions Telephoning
Least Cost Routing (LCR)
Whenever you make an external call, your system automatically uses LCR to set up a connection to a network
operator that has been selected by the system administrator. If you do not wish to use this preferred
connection and want to select a network operator yourself for each call (i.e. on a call-by-call basis), then
before making the call, select the
LCR off
entry from the menu described in the section entitled MenuCard
“Selection” in the Idle State .
This is only necessary if LCR has been configured for you in the Comfort Pro. Consult your system
administrator about this.
N
Note: Baby call and external call forwarding are not automatically switched via
preferred connections. In this case, if the network operator you wish to use is not the
default operator, you can key in the appropriate operator’s code digits before entering
the call number.
Transmission of Call Numbers
With ISDN there are different features which allow or prevent the transmission of (external) call numbers
between subscribers.
“CLIP” Feature
“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.
