3. 3. 1 Analysing and Editing the CLIP
The following information is necessary for specifying the CLIP properties in a PISN
correctly. . This sub-chapter can be skipped in the case of the configuration of a
stand-alone PBX.
The system analyses and adapts the CLIP number of an incoming call as accurately
as possible so that the CLIP number is always displayed correctly, even in a PISN.
For this purpose CLIP number prefixes such as regional prefix, prefix and code are
evaluated, and the type of number adapted.
The tables below show how the system handles the type of number and the CLIP
number of an incoming call.
Tab. 11 Handling a CLIP number with NPI-type PNP or unknown
Tab. 12 Handling a CLIP number with NPI-type E.164
