Question: Upon receiving RTP media packets from a permitted floor participant, what action does the IWF (Interworking Function) floor control server take regarding timer T1 (End of RTP media), assuming the upper limit for timer T3 (Stop talking grace) is greater than that of T1?
Option 1: The IWF floor control server restarts timer T1, which may expire based on its set duration.
Option 2: The IWF floor control server pauses timer T1 until further instructions are received from the media distributor.
Option 3: The IWF floor control server stops (cancels) timer T1 to prevent its expiration during the transmission.
Option 4: The IWF floor control server adjusts the upper limit of timer T1 to match that of timer T3.
Explanation: According to the provided context, upon receiving an indication of RTP media packets from a permitted floor participant, the IWF floor control server shall restart timer T1 (End of RTP media). This action is independent of the comparative values of timers T1 and T3 unless specifically noted otherwise. Thus, the correct response reflects the server's immediate action upon receiving such packets.
