Question: In a CAMEL Call Party Handling (CPH) scenario, when a call leg is moved from one call segment to another, what happens to the grouped field for that call leg in the respective Charging Data Records (CDRs)?
Option 1: The grouped field for that call leg is merged with another existing field in the original CDR.
Option 2: The grouped field for that call leg remains open in the original CDR, and a duplicate is created in the new CDR.
Option 3: The grouped field for that call leg is deleted from both CDRs to avoid duplication.
Option 4: The grouped field for that call leg is closed in the original CDR, and a new grouped field is opened in the CDR of the call segment it was moved to.
Explanation: This is the correct procedure to maintain accurate and up-to-date charging information when call legs are rearranged between call segments. Closing the old field and opening a new one ensures that each CDR reflects the current state of its respective call segment, preventing errors in billing or charging management.
