3.4 CLIP with Outgoing Calls
With an outgoing call the CLIP number is transmitted along with the NPI and TON
information. In principle there are two possible variants for creating a CLIP
number:
• The PBX creates the CLIP number automatically, based on the origin and rout-
ing of the call.
• A number is entered permanently as the CLIP number in the subscriber config-
uration.
3.4.1 Creating the CLIP in the PBX
With the "Automatic CLIP = Yes" setting in the subscriber configuration, the PBX
generates a CLIP number. If there is a suitable DDI number for the calling sub-
scriber, that number will be used.
A suitable DDI number is a number in a direct dialling plan which
• is linked directly or through a user group to the calling subscriber via a call dis-
tribution element, and
• is linked with the same trunk group via which the outgoing call is routed.
If there is more than one suitable DDI number, the lowest one is used.
The trunk group settings are used as the numbering plan identifier and type of
number.
If there is no suitable DDI number, the trunk group settings are used for calls into
the public network (Fig. 2.14), for calls into the private leased-line network it also
depends how the automatic CLIP is set in the trunk group configuration (Fig.
2.16).
3.4.2 Entering a fixed CLIP
In practice a permanent CLIP number is used if the CLIP of the subscriber con-
cerned is always 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
348).
