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 routing
of the call.
• A number is entered permanently as the CLIP number in the user configuration.
3. 4. 1 Creating the CLIP in the PBX
With the Automatic CLIP = Yes setting in the user configuration, the PBX generates a
CLIP number. If there is a suitable DDI number for the calling user, 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 user via a call distribution
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. 14, page 48), for calls into the private leased-line network it
also depends how the automatic CLIP is set in the trunk group configuration
(Fig. 16, page 49).
