Question: In a Local Call Local Switch (LCLS) scenario, when an MSC server determines that local switching should be disconnected in a SIP-I based CS core network, which specification dictates the call clearing procedures?
Option 1: 3GPP TS 23.205
Option 2: 3GPP TS 23.231
Option 3: 3GPP TS 29.060
Option 4: The specific specification is not dependent on the type of CS core network (BICC or SIP-I) for LCLS disconnection
Explanation: According to the context, for a SIP-I based CS core network, call clearing procedures for disconnecting local switching in an LCLS scenario are performed in accordance with 3GPP TS 23.231, highlighting the importance of adhering to specific standards for different core network types.
