8. 3. 2 Surcharge calculator
The surcharge calculator is used to assess surcharges on top of the official call
charges.
With the charge settings (=b4), four independent surcharge calculators can be con-
figured and allocated to the cumulative 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 dis-
played include surcharges.
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 Multiplier with which the call charges
in the corresponding range limits are multiplied.
The basic surcharge is added to every chargeable call.
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.
