Question: Upon receiving an RTP media packet with payload from the associated floor participant, what actions does the floor control interface towards the MCPTT client in the IWF floor control server take?
Option 1: It rejects RTP media packets to prevent overload and transitions to 'U: pending Floor Grant' state.
Option 2: It buffers RTP media packets for later processing but immediately moves to the 'Active' state.
Option 3: It only acknowledges receipt of RTP media packets without forwarding them, staying in the 'Idle' state.
Option 4: It forwards RTP media packets to the media distributor and remains in the 'U: pending Floor Revoke' state.
Explanation: This correct answer reflects the proper handling of RTP media packets as per the specified behavior for interworking between MCPTT (Mission Critical Push To Talk) and LMR (Land Mobile Radio) systems. Forwarding the packets ensures continuous communication flow, while remaining in the 'U: pending Floor Revoke' state indicates that the system is awaiting further floor control instructions without prematurely changing its operational state, thus maintaining protocol integrity.
