Question: What happens to the bootstrap data channel when an IMS MMTel session is released?
Option 1: It remains available for future sessions.
Option 2: It is terminated along with the release of the call.
Option 3: Its termination requires a separate SDP negotiation.
Option 4: It automatically converts to an application data channel.
Explanation: According to IMS session management principles, resources allocated specifically for a session (like the bootstrap data channel) are released when the session is terminated to free up network resources. Thus, the bootstrap data channel, established for the IMS MMTel session, would logically be terminated upon the session's release, ensuring efficient resource allocation.
