Make Retail Tariff from Wholesale Tariff explained

Retail Tariff from Wholesale Tariff is done by following algorithm:

1. The highest Rate in Wholesale Tariff for Destinations in Destination Group (DG) is selected.
2. This rate is modified by adding a value or percentage to it.

Example

Imagine we have a Wholesale Tariff with the following rates for the USA:

• Prefix 1, rate 0.01.
• Prefix 12, rate 0.02.
• Prefix 123, rate 0.03.

And we have Destination Group USA with Destinations (1;12;123) in it.

Now, if we want to create a Retail Tariff by adding 0.005 to the Wholesale tariff, we will have a price for USA Destination Group = 0.035.

For example, the highest rate from Destinations is selected and modified.

Inner mechanics

The wholesale tariff line will have these values:

• connection_fee
• min_time
• increment_s

When transforming to Retail, these Advanced Rates are created:

Based on which variable	FROM	DURATION	TYPE	ROUND BY	RATE	Comments
connection_fee	1		event		connection_fee	This record is only created when connection_fee > 0.
min_time	1	min_time	minute	min_time	rate	This record is only created when min_time > 0.
increment_s	min_time + 1	-1 (means 'infinity')	minute	increment_s	rate	This record is always created.
