Bosch Security Systems B.V. | 2003 December | MM Remote Interface Description
Note that a delegate does not really turns on its microphone, but he makes a Request to speak. Depending
on the operation mode and the current lists, he is added to the SPK list or the RTS list. On this Request-to-
Speak-event also a remark has to be made if the unit/delegate is in the Speakerslist but with the microphone
off (which is possible with the function MM_C_SET_MICRO_ON_OFF, see section 3.3.1). In that case for all
operation modes a MM_C_SPK_REMOVE_ON_PC update notification is first given for the current unit after
which the update notifications according to the event matrix are generated.
