CLIP of an Incoming Call
User A calls user B:
User A sends his CLIP, which is received in the communication server by the trunk
group, processed and displayed to user B.
For more details see as of page 80
.
CLIP of an Outgoing Call
User C calls user D:
User C sends his CLIP number, which is processed in the communication server. If
there already is a direct dialling and a corresponding allocation, the CLIP number is
adapted and sent to user D.

The default configuration has been selected so that the CLIP display is correct. The
relevant settings do not normally have to be adjusted.
4. 3 CLIP with Incoming Calls
The CLIP number of an incoming call is processed and presented in two stages:
• Analysis and processing of the CLIP number
• Presentation of the CLIP number on the destination user’s terminal
4. 3. 1 Analysing and Editing the CLIP
The following information is necessary for specifying the CLIP properties in a PISN cor-
rectly. This sub-chapter can be skipped in the case of the configuration of a stand-
alone communication server.
The system analyses and adapts the CLIP number of an incoming call as accurately as
possible so that the CLIP number is always displayed correctly, even in a PISN.
For this purpose CLIP number prefixes such as regional prefix, prefix and code are
evaluated, and the type of number adapted.
The tables below show how the system handles the type of number and the CLIP num-
ber of an incoming call.
