The Sippy Softswitch can round the Call Cost to the needed decimal. This feature is part of version 4.3 Sippy Softswitch.
The balance of the particular account that uses the tariff with non-default Cost Decimal Precision would be debited based on the calculated rounded cost of the call.
The balance of the particular vendor with non-default Cost Decimal Precision would be debited based on the calculated rounded cost of the call.
Default Cost Decimal precision
This method is the default one. No particular rounding for the cost up to 20th digit is being done, and the rating works based on all digits from the cost of some prefix. For example;
A call with a cost of 1.0123456789012345678811 USD will be rounded to 20th digit after the dot. The call cost would be recorded as 1.01234567890123456788 USD.
A call with a cost of 1.0123456789012345678899 USD will be rounded to 20th digit after the dot. The call cost would be recorded as 1.01234567890123456789 USD.
Custom Cost Decimal Precision
This method rounds the call cost after the last configured digit after the dot.
For example, having the Cost Decimal Precision = 2:
A call with a cost of 1.0123456789012345678811 USD will be rounded to 2nd digit after the dot. The call cost would be recorded as 1.01 USD.
A call with a cost of 1.0153456789012345678899 USD will be rounded to 2nd digit after the dot. The call cost would be recorded as 1.02 USD.
A call with a cost of 1.0173456789012345678899 USD will be rounded to 2nd digit after the dot. The call cost would be recorded as 1.02 USD.
Rounding the call cost
Call Cost option allows to select proper rounding method, whether it's Round (rounds the call cost to the nearest digit based on the typical round approach) or Round Up (always round cost up).
The following table illustrates the results of both default and the custom cost decimal precision methods, with different Calls Cost Round policy applied
| Calculated Cost Of The Call | Default Cost Decimal Precision | Custom Cost Decimal Precision (For the Cost Decimal Precision = 2) | Calls Cost Round | Calls Cost Round Up |
| 1.0103456789012345678811 | 1.01234567890123456788 | 1.01 | 1.01 | 1.02 |
| 1.0123456789012345678811 | 1.01034567890123456788 | 1.01 | 1.01 | 1.02 |
| 1.0153456789012345678899 | 1.01534567890123456789 | 1.02 | 1.02 | 1.02 |
| 1.0173456789012345678899 | 1.01734567890123456789 | 1.02 | 1.02 | 1.02 |
