Question: In IMS-based VoIP interception, where the content of communications is separated from packet data network interception, which of the following scenarios is NOT covered by this standard?
Option 1: Single CSP handling both media transport and signaling nodes
Option 2: Different CSPs handling media transport and signaling nodes within the same country
Option 3: Interception for IMS-based VoIP calls using SR-VCC (Service Centralized VCC)
Option 4: Scenarios where media transport nodes and signalling nodes are handled by different Communication Service Providers (CSPs)
Explanation: This scenario is explicitly beyond the scope of this standard, highlighting the importance of understanding scope boundaries in telecom standards, particularly for lawful interception in IMS-based VoIP across different CSPs.
