Question: Upon expiry of the T12 (Stop talking dual) timer in an MCPTT (Mission Critical Push To Talk) scenario, what action does the IWF (Interworking Function) floor control server take regarding RTP media packets distribution to other media endpoints?
Option 1: Continues distributing RTP media packets to all media endpoints to ensure seamless communication.
Option 2: Requests the media distributor in the IWF to stop distributing RTP media packets to other media endpoints.
Option 3: Starts distributing RTP media packets to additional media endpoints not previously receiving them.
Option 4: Modifies the content of RTP media packets before continuing their distribution.
Explanation: Upon expiry of the T12 timer, the floor control arbitration logic in the IWF floor control server stops distributing RTP media packets to other media endpoints, ensuring resources are managed efficiently and unnecessary packet distribution is halted.
