In AlphaPro, Exchange & System -> Events, insert events with the following parameters:

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
Action:	WUDD 500 0 CNG 9 1

---

The conference is stopped by dialing event trigger 9534 from the Bridge:

Event Owner:	The Bridge station
Event type:	15 - Event Trigger
Subevent:	0
When change to:	ON
When related to:	Directory number: 9534
Action:	CNG 9 0

---

When a user releases the M-key, the station will still be feeding the conference:

Event Owner:	UDP Group 1 (Active users)
Event type:	31 - M-key
Subevent:	255
When change to:	OFF
When related to:	All
Action:	pause $CONF_TALK L%1.dir

---

When the Bridge releases the M-key, the Active User will be talking into the conference. A 1.0 sec timer is used to retrigger the Active Talker in case the Bridge (or radio) presses M-key briefly:

Event Owner:	UDP Group 2 (Bridge and Radio)
Event type:	31 - M-key
Subevent:	255
When change to:	OFF
When related to:	All
Action:	$CONF_TALK L%udd(500) $ST L%1.dir W10 L99

---

The 1.0 sec timer retriggers the Active Talker in case the Bridge (or radio) pressed the M-key briefly:

Event Owner:	UDP Group 2 (Bridge and Radio)
Event type:	21 - Event Timeout
Subevent:	0
When change to:	ON
When related to:	Directory number: 99
Action:	$CONF_TALK L%udd(500)

---

When someone is talking into conference 8201, on the station 138 switch off the "Active User LED" for the previous user, and switch on the "Active User LED" for the current user. Store the current active user in UDD 501. If the talker is member of group 10 (i.e. all users except bridge), update the Active User UDD 500:

Event Owner:	UDP Group 8 (All stations)
Event type:	08 - Conversation Outgoing
Subevent:	0
When change to:	ON
When related to:	Directory number: 8201
Action:	OWN r 138 IND %2.phy %2.dak(I%udd(501)) 2 3 OFF IND %2.phy %2.dak(I%1.dir) 2 3 ON WUDD 501 %1.dir IF %sgm(%1.phy,10) WUDD 500 %1.dir ENDIF

---

Turn the red LED steady ON when a station joins the conference 8201:

Event Owner:	UDP Group 8 (All stations)

Subevent:	0
When change to:	ON
When related to:	Directory number: 8201
Action:	OWN r 138 IND %2.phy %2.dak(I%1.dir) 1 1 ON

- 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.
