Question: In an MCPTT session, upon receiving a Floor Granted message with the G-bit set to '1' (Dual floor), what action does the floor control server interface take regarding sending Floor Taken messages?
Option 1: Sends a Floor Taken message to all participant interfaces, including the one to which the Floor Granted message is sent.
Option 2: Sends a Floor Taken message only to the floor participant interface to which the Floor Granted message is sent.
Option 3: Sends a Floor Taken message to floor participants that will listen to the RTP media from the overriding MCPTT client, based on local policy.
Option 4: Does not send any Floor Taken messages when the G-bit is set to '1' (Dual floor).
Explanation: When the Floor Indicator field in the Floor Granted message has the G-bit set to '1', indicating a dual floor scenario, the floor control server interface selectively sends Floor Taken messages. These are sent to participants who, according to local policy, will listen to the RTP media from the overriding MCPTT client. This selective sending ensures that only relevant participants are notified of the floor status change in a dual-floor context, maintaining efficient communication within the group call.
