Question: In an IMS centralized services context, where Call Control is solely done in IMS for SeDoC (Service Centralization and Continuity), what is the primary role of Call Control functionality on the A/Iu-cs side of the MSC Server?
Option 1: To manage all call setups and teardowns for both CS and PS domains.
Option 2: To handle specific local exceptions, such as routing undetected emergency calls (e.g., Germany's 110) to E-CSCF.
Option 3: To oversee Radio Resource Management (RR) and Mobility Management (MM) for seamless handovers.
Option 4: To act as a gateway for all incoming calls from the PSTN to IMS.
Explanation: The correct answer highlights the specialized local call control function required on the A/Iu-cs side of the MSC Server enhanced for SeDoC, ensuring specific exceptions (like undetected emergency calls) are correctly identified and routed to the E-CSCF. Primary Call Control for regular calls is handled by IMS.
