Question: In independent Lawful Interception (LI) of IMS-Conferencing, what is the primary objective when LI is activated on a conference-ID, and how does it relate to basic VoIP calls?
Option 1: The LI is specifically targeted at the conference-ID, isolating interception to only IMS conferencing without correlating it with the underlying basic VoIP call.
Option 2: The activation of LI on a conference-ID automatically triggers a broader interception scope that includes all associated basic VoIP calls for comprehensive monitoring.
Option 3: Independent LI in this context requires simultaneous activation of both correlationNumber and imsVoIP parameters to filter out non-conferencing communications effectively.
Option 4: Activating LI on a conference-ID has no differentiation in treatment, implying that both IMS conferencing and basic VoIP calls are subject to the same interception rules without distinction.
Explanation: In the context of independent Lawful Interception of IMS-Conferencing, activating LI on a specific conference-ID is designed to narrowly focus the interception efforts. This approach ensures that only communications associated with the identified conference-ID (pertaining to IMS conferencing) are intercepted, without unnecessarily broadening the scope to include basic VoIP calls that may not be relevant to the lawful interception's objective. This targeted approach helps in maintaining privacy and reducing unnecessary data collection from unrelated communications.
