4. 4 CLIP with Outgoing Calls
With an outgoing call the CLIP number is transmitted along with the NPI and TON in-
formation. In principle there are two possible variants for creating a CLIP number:
• The communication server creates the CLIP number automatically, based on the or-
igin and routing of the call.
• A number is entered permanently as the CLIP number in the user configuration.
4. 4. 1 Creating the CLIP in the communication server
If in the user configuration the setting Create CLIP number automatically is acti-
vated, the communication server 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 ele-
ment, 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. 35), for calls into the private leased-line network it also depends on
how the automatic CLIP is set in the trunk group configuration ( =bg) (Fig. 37
).
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 251).
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 98
).
The required CLIP number, the Numbering plan identifier (NPI) and Number
type (TON) are entered in the user configuration. The setting Create CLIP number
automatically must be deactivated.
For the Numbering plan identifier (NPI) E.164 is set in normal case.
