Question: In a CAMEL environment, when using the SplitLeg operation to move a leg into a new Call Segment (CSID1) that doesn't exist, what is the required phase of the BCSM for the leg to be split?
Option 1: Idle Phase
Option 2: Alerting or Active Phase
Option 3: Held Phase or Suspended State
Option 4: Disconnected Phase
Explanation: According to CAMEL specifications for SplitLeg operations, when moving a leg into a new Call Segment (CSID1) that doesn't exist, the BCSM for the leg to be split must be in either the Alerting Phase or the Active Phase. This ensures that the call is in an appropriate state to be successfully split and managed within the new Call Segment, maintaining continuity of service.
