Identification elements97System functions and features as of R3.0syd-0367/1.3 – R3.0 – 03.20134. 6. 4 CLIP/CLIR settingsThese settings are used to truncate prefixed access digits so that the CLIP numberis as short as possible.To enable the communication server to interpret CLIP numbers correctly, the sys-tem’s own regional prefixes need to be entered under CLIP/CLIR:• International and national prefixes for the locations ("00" and "0" for Switzerland,"00" and "-" for France)• Country code and toll area code of the location (for Switzerland "41", for Geneva"22"", see also "Numbering Plan Identifier E.164", page 48).Aastra Intelligent Net:In an AIN the nodes may be spread over different regions or even coun-tries. Some settings do not apply throughout the system but only to oneregion. A region is assigned to one or more AIN nodes. An region can alsobe assigned for each trunk group. The trunk group allocation takes prior-ity over the node-specific allocation.Display CLIRWhen CLIR is activated (suppress CLIP) the public network provider will still send aCLIP to special customers, for instance the fire brigade and the police. The CLIR in-formation will, however, include the CLIP (see also "Suppressing CLIP / COLP (CLIR /COLR)", page 85).In the private leased-line network a CLIP is always sent with an activated CLIR. It isalso provided with the CLIR information.If Display CLIR = yes, a CLIP with CLIR information is still displayed in the case of in-coming calls.In internal traffic, a suppressed CLIP is always displayed.4. 6. 5 Numbering planThe CLIP number is prefixed with the regional prefix for outgoing calls to a PISNuser or via a trunk group with Network type = private.For incoming calls, the regional prefix is removed from the CLIP number (providedit begins with that digit sequence).
