4. 4. 2 Entering a fixed CLIP
In practice a permanent CLIP number is used if the CLIP of the user concerned is al-
ways to remain the same in the public network, regardless of the path used for
routing an outgoing call. Break-out is a typical application (see page 270).
If a call goes out to the public network, the permanent CLIP number is retained un-
changed together with the numbering plan identifier NPI and the type of number
TON, even if the call is routed via another PINX (see example on page 103).
The CLIP number required, the numbering plan identifier NPI and the type of
number are entered in the user configuration. The Automatic CLIP setting, also in
the user configuration, must be set on No.
E.164 is normally set for the numbering plan identifier NPI.
4. 4. 3 Suppressing CLIP / COLP (CLIR / COLR)
If CLIR = Yes has been set in the caller’s user configuration, the information sent
along with the CLIP and COLP numbers specifies that they are not to be displayed
to the call’s recipient (CLIR: Calling Line Identification Restriction, COLR: Connected
Line Presentation Restriction). In this case the network provider does not forward
the CLIP number to the recipient (the CLIP number may nonetheless be sent to a
number of public authorities, such as the police, see also "Display CLIR", page 97 ).
The same setting is also used to prevent the name being displayed to the call's re-
cipient. The suppression of CNIP (Calling Name Identification Presentation) and
CONP (Connected Name Identification Presentation) is called CNIR (Calling Name
Identification Restriction) and CONR (Connected Name Identification Restriction).
Depending on the network provider it may be necessary to subscribe to CLIR.
For each user CLIR can only be activated permanently or temporarily for one call
(see "Suppression of the call number display", page 514).
