The inputs to calculating the cost of a call are:
...
- Use the site, trunk and dialled number to find the carrier used for the call.
- Use the carrier and dialled number to find the tier used for the call.
- Use the tier and date/time of the call to find the rate. Calculate the cost for a call of this duration, taking care that a new rate is started when the call passes into another charging period.
Calculate the Carrier
Two factors determine the carrier associated with a call. Initially the carrier is determined from either the trunk or trunk group used by the call, and then both it and the dialled number can be changed by digit modifications associated with the trunk group.
...
With each trunk group are associated zero or more digit modifications. The digit modifications associated with a trunk group may result in changes to both the dialled number and the carrier for the call.
Calculate the Tier
The set of time rates which are applied for a particular call are called a tier. For instance a local call with a flat rate of $0.25 and an intercapital call which is charged at $0.12 a minute during the day and $0.13 during the night use different tiers. iPECS Report Plus has four different types to identify the tier that a call uses. Each of these is checked in order.
...
Distance - the latitude and longitude of each exchange is known. From this the distance between the two exchanges can be calculated. Then the distance is matched with the distance bands of each tier to find the appropriate tier.
Calculate the Rate Cost
Once the tier has been found the date/time of the call is used to find the call’s rate and the charges associated with that rate in the tier are used to find the cost. Associated with each carrier are one or more period names and period sets. A period set assigns a period name to all times of all days of the week, including holidays.
