Question: In an MCPTT (Mission Critical Push To Talk) scenario, when an IWF (InterWorking Function) floor control server receives RTP (Real-time Transport Protocol) packets from a media distributor, what action is taken if a floor participant's indication shows they are overriding without revoke?
Option 1: The IWF floor control server discards the RTP packet to prevent override conflicts.
Option 2: The IWF floor control server forwards the RTP packet to the associated floor participant.
Option 3: The IWF floor control server changes its state to 'U: not permitted' to block further transmissions.
Option 4: The IWF floor control server sends an override revoke signal before taking any action.
Explanation: According to the MCPTT media plane control interworking specifications, if a participant's indication shows they are overriding without revoke, the IWF floor control server is required to forward the RTP packet to the associated floor participant. This ensures continuous communication flow during an override situation without immediate revocation, maintaining the integrity of the mission-critical communication session.
