Surcharge calculator
The surcharge calculator is used to assess surcharges on top of the official call
charges.
Four independent surcharge calculators can be configured and allocated to the cu-
mulative counters of the users or rooms. Call charges are indicated to each user
(only on system phones with a display) while the call is in progress. If the user has
been allocated a surcharge calculator, the call charges displayed include sur-
charges.
The cost curve of a surcharge calculator is defined by the basic surcharge and
4 cost ranges.
For each of the 4 ranges the user can specify a factor with which the call charges in
the corresponding range limits are multiplied.
The basic surcharge is added to every chargeable call. If the basic surcharge is to be
applied only as of, say, –.20, the following settings are necessary:
Range 1: surcharge factor 0; start of range 2: –.20.
This means, for example, that a hotel guest will only be charged for a call as of the
second metering pulse.
Call charges on cost centres allocated to network interfaces or call distribution ele-
ments are never adapted via the surcharge calculator.
No surcharge calculators are configured after an initialization.
