Symptoms

There was a scenario where the quantity granted by the PCM_OP_TCF_AAA_AUTHORIZE opcode was not correct.

1. The subscriber has $0.60 remaining credit on the monetary balance.
2. The subscriber was placing a voice call rated at $0.25 per minute with a minimum event quantity of 1 minute and an increment quantity of 1 minute.

The result was:
The PCM_OP_TCF_AAA_AUTHORIZE opcode returned a successful authorization even when credit limit was exceeded.

In an attempt to solve this issue,  the user has configured the INCR_QUANTITY to 60 seconds in the "/config/reserve/st_cellular/voice" object and the tested again the same scenario.

To grant a quota of 160 seconds according to the subscriber's monetary balance and the event quantity rounding rules, with setting the INCR_QUANTITY to 60 seconds, only 120 seconds should have been granted.

It seemed like both C-Rating engine and real-time pipeline did not take into account the event quantity rounding rules configured at the product level in the price list in the authorization process when credit limit was exceeded.
