wPrioId Passes the prio-status of the chairman unit. This priority
information indicates to the remote controller that the delegate
units can be muted due to a priority key pressed on this
chairman-unit. Although the microphone is turned on, the
delegate can not
yet speak.
This parameter can be one of the following values:
• MM_C_PC_PRIO_ON
• MM_C_PC_PRIO_OFF
• MM_C_PC_PRIO_NONE
The ‘NONE’ values of the parameters ‘wMicroId’ and ‘wPrioId’ indicate that the specific
parameter is not used.

these parameters are returned with the events:
