Matrix PRASAR UCS System Manual 615
Call Cost Calculation (CCC)
What’s this?
PRASAR UCS can calculate the cost in amount for the external calls made by the extension users.
The call cost is calculated according to the tariffs offered by the ITSP’s. Different types of tariffs are provided by
different ITSP’s. These may be:
• Time Based Tariffs, for example, free calling from 11.00 p.m. to 6.00 a.m.
• Special Day Tariffs, for example, subsidized calls rates on August 15.
• Tariffs according to the Geographical Distances, for example, calling rates for UAE differ from calling rates
to Canada.
Using the Call Cost Calculation feature, the system calculates the cost of the call according to the duration of the
call interpreted in terms of units and the charge applicable for the duration as per the service provider.
How it works
For this feature to work,
• you must get the tariff details from the ITSP’s and configure the same.
• determine the outgoing trunk for the calls according to the type of calls, namely, local calls, national calls or
international calls.
PRASAR UCS will calculate the cost of the call as follows:
• When the call is made from a trunk, the system checks the Call Cost Calculation Pulse Rate Option, 1 to
4 assigned to the trunk, on the basis of the Call Cost Calculation Time Schedule configured for the
outgoing call.
Each Call Cost Calculation Pulse Rate option contains a Pulse Rate Type for the Pulse Rate, which is
assigned in the Area Code Table.
• The system matches the Number dialed by the extension user with the Area Code Table configured in the
system. When the area code matches with an entry in the table, the system obtains the Pulse rate type
configured for the Call Cost Calculation Pulse Rate option assigned to the trunk.
•This Pulse Rate type obtained from the Area Code Table is checked in the Pulse Rate table to obtain
the corresponding duration and cost to be applied for the call duration. The Pulse Rate Table may be the
Normal Pulse Rate Table or Discounted Pulse Rate Table, depending on the day of the call. The
system uses the built-in RTC to determine the day.
• The Pulse Rate Type applied (duration and cost) is divided into two parts for each time zone:
• First unit.
• Additional units.
• Number of Units is derived from the pulse rate at the time of the call and duration of the call. System
acquires the pulse rate type and call duration with the help of in-built RTC.
