Question: Upon receiving a Floor Release Multi Talker message from the Floor Control Server, what state should the Floor Participant Interface toward the MCPTT (Mission Critical Push To Talk) client remain in, considering the current specification?
Option 1: Transition to 'P: has permission' state to allow continuous transmission.
Option 2: Enter a 'Standby' mode awaiting further instructions from the Floor Control Server.
Option 3: Remain in the 'P: has no permission' state, as per specified protocol behavior.
Option 4: Automatically initiate a request for floor grant to the Floor Control Server.
Explanation: The correct answer is Option 3 because, according to the provided telecom specification, upon receiving a Floor Release Multi Talker message, the interface should remain in the 'P: has no permission' state. This behavior aligns with the noted limitation that the multi-talker feature is not supported in the current document, implying that granting or managing multiple talker permissions is not within the scope of this specification. Thus, maintaining the 'no permission' state ensures adherence to defined protocol boundaries.
