System functions and features as of R4.1
syd-0570/1.2 – R4.1 – 08.2016
Notes:
– All calls in the connection data collection are always entered, regardless of the chosen
action.
– For mobile/external users, virtual PISN users and MMC mobile phones, the external call
number is always first replaced with the internal user number, before the comparison with
the blacklist is made.
System configuration
The blacklist can be created in the Blacklist ( =zm) view, or imported from an Ex-
cel file.

6. 3. 2. 2 CLIP based routing
With CLIP based routing, it is possible to route incoming external or internal calls
based on their CLIP. This way certain calls can be rejected, left to come to "nothing" or
routed to a specific destination. For this create call routing tables then, for each switch-
ing position, assign them one or more call distribution elements.
Examples for valid entries in the call distribution tables.
• +234
• +41321234567
•3868
•3867
•386
•X
•?
Notes:
– Each external CLIP number must start with a '+'.
– “X” stands for incoming calls with call identification restriction (CLIR).
– “?” stands for incoming calls without CLIP (unknown number).
– “X” and “?” are specific entries and cannot be combined with digits.
– The table is sorted automatically after an entry is saved. Short numbers starting with the
same digits are given below.
An external or internal call to a CDE, to which a routing table is assigned on the current
switching position, is handled as follows:
Parameter Remarks
