3. 6. 2 PISN users
Number setting
The call number entered under Number is compared with the CLIP number of an in-
coming call. If the two numbers match up, the PISN user number is displayed as the
CLIP with NPI = private and TON = level 0.
CLIP selection setting
See "Internal call to a PISN User", page 56.
3. 6. 3 Trunk groups
Call if NPI unknown setting
If a call with NPI = unknown is received, it is signalled with the internal or external
ringing pattern on the basis of this setting. It is also decided at the same time
whether the exchange access prefix (0-) should precede the CLIP number.
Truncate CLIP setting
A digit sequence can be configured here. If the sequence matches the initial digits
of the CLIP number received, the digits will be truncated. This setting is normally
used to remove any superfluous "0".
CLIP automatic setting
This setting is effective only if Network type = private has been set in the trunk
group configuration.
If CLIP automatic = yes, the numbering plan identifier and type of number are left
unchanged.
If CLIP automatic = No, the numbering plan identifier and type of number are taken
from the trunk group setting, but not the actual CLIP number. This may be neces-
sary in cases where connected third-party systems do not process numbering plan
identifiers and types of number correctly.
Numbering Plan identifier, Type of Number, Number
These settings are used if the CLIP number could not be created automatically. This
is the case when there is no suitable DDI number available with a call to the public
network.
