Goal

Issue is that user is seeing 30 second impact for zero duration call. That is:

• When passing 0 USU (used service units) for each of the Update and Terminate Voice request, there is impact of 30 second duration in the rated event that is loaded in database.
• Discount Offer has quantity tiers with 30 second (sec) charging interval ranging from 0 to 30 sec, and 30 sec to NO MAX, to track the voice usage.
• Charge offer is configured with unlimited seconds.
• In below scenarios, USU is not passed by network in the CCA (Credit-Control-Answer) and still it is getting charged.

Scenario 1 - Subscriber A is calling Subscriber B and Subscriber B did not receive call within 60 sec (as waiting time is 60 sec)

• Actual Result- Impact is based on Duration RUM configured as END_T - START_T. In the below case, Subscriber A is calling Subscriber B and Subscriber B did not receive call within 60 sec (as waiting time is 60 sec). 62 sec got impacted considering below Start time and End time. For this request, Terminate request was received with 0 USU.
  
    {startTimeOverride=2023-04-04T14:57:15+03:00[UTC+03:00]}
    {endTimeOverride=  2023-04-04T14:58:17+03:00[UTC+03:00]}
  
  
• Expectation - 0 sec to be charged for any usage with USU as 0.

Scenario 2 - Subscriber A is calling to Subscriber B and Subscriber B did not receive call within 40 sec and then Subscriber A cancels call.

• Expectation - 0 sec to be charged for any usage with USU as 0.
