The conference is started by dialing event trigger 9533 from the Bridge. UDD 500, which contains the current Active User, is cleared:

Event Owner:	The Bridge station
Event type:	15 - Event Trigger
Subevent:	0
When change to:	ON
When related to:	Directory number: 9533

- A user talks into the conference by pressing the M-key. When the M-key is released, the users in UDP 1 shall remain the active talker. This event will force the user to feed the conference when M is released, and the directory number of the active user is stored in UDD 500.
