616 Matrix PRASAR UCS System Manual
Total Units = First Unit + Additional Unit.
If the call duration is less than the pulse rate of the first unit then additional unit is zero.
Call Units = (Call duration in seconds)/(Pulse rate in seconds).
• If the duration of the call is less than or equal to one unit,
Cost of Call = Cost of First Unit + Service Charge as applied.
• If the duration of the call is more than one unit,
Cost of Call = [Cost of First Unit + (Number of Additional units x Cost for Additional units)] + Service
Charge as applied.
• The system applies the rates as configured in the Normal Pulse Rate Table for all the days, except when it
detects a day configured in the Discounted Pulse Rate Schedule. These are special days when special
Tariffs are offered.
For the days configured in the Discounted Pulse Rate Schedule as special days, the system checks the
the duration and cost of the First unit and the Additional units configured in the Discounted Pulse Rate
Table.
PRASAR UCS uses the Cost of the Call for SMDR. This cost is deducted from the Call Budget (Amount), if allotted
to the trunk and also from the Call Budget, if assigned to the extension users.
The logic for call cost calculation is explained with the help of an example:
• An Outgoing Call is made using trunk, SIP Trunk-1.
• On SIP Trunk-1, Call Cost Calculation is configured as follows:
• Call Cost Calculation Pulse Rate option = 1
• Call Cost Calculation Schedule
• Time Zone 1 = Start Time: 00:00, End Time: 22:00
• Time Zone 2 = Start Time: 22:01, End Time: 23:59
• Assign Trunk Feature Template 1 to SIP Trunk-1. Configuring the Call Cost Calculation parameters in
the Trunk Feature Template as follows:
