Question: When an IWF (Interworking Function) floor control server detects the overriding IWF media endpoint disconnecting from an MCPTT (Mission Critical Push To Talk) call, what action does it take regarding RTP (Real-time Transport Protocol) media packet distribution?
Option 1: It continues distributing RTP media packets to ensure seamless communication among remaining participants.
Option 2: It requests the media distributor to buffer RTP media packets temporarily before redistributing them.
Option 3: It shall request the media distributor in the IWF to stop distributing RTP media packets received from the overriding IWF media endpoint to other media endpoints.
Option 4: It redirects RTP media packets to a default endpoint for further processing.
Explanation: This action is crucial for efficiently managing resources and preventing unnecessary data transmission when a controlling endpoint disconnects. By stopping the distribution of RTP media packets from the overriding IWF media endpoint, the IWF floor control server ensures that other endpoints are not receiving redundant or irrelevant media streams, thus maintaining the integrity and efficiency of the MCPTT call.
