Question: Upon receiving RTP media packets from a permitted MCPTT media endpoint, what actions does the floor control arbitration logic in the IWF floor control server take regarding timers?
Option 1: Starts T11 (End of RTP dual) timer and stops T12 (Stop talking dual) timer if already running.
Option 2: Restarts T11 (End of RTP dual) timer only, without any action on T12 (Stop talking dual) timer.
Option 3: Stops both T11 (End of RTP dual) and T12 (Stop talking dual) timers if they are running.
Option 4: Starts T12 (Stop talking dual) timer if not already running, and restarts T11 (End of RTP dual) timer.
Explanation: According to the specified behavior for handling RTP media packets from an MCPTT media endpoint, the floor control arbitration logic must manage timers to coordinate floor control and media transmission properly. Starting T12 (if not running) ensures dual talking scenarios are managed, while restarting T11 ensures timely closure of RTP dual transmissions. This coordinated action on both timers is crucial for maintaining orderly communication in Mission Critical Push To Talk (MCPTT) scenarios.
