Group Call - PTT function
From Zenitel Wiki
This article describes how to configure a DAK key on a station to activate a Group Call when the key is pressed, and cancel the group call when the DAK key is released.
Configure the group to use "Automatic M-key"
In AlphaPro, select the Group Call, and enable "Automatic M-key". When enabled, there is no need to press the M-key to open the microphone during the group call:
In the Event Handler, the event 30 (Station DAK or Input) is triggered when a DAK Key is pressed.
The following event will activate group call 85 when the DAK key number 3 (= Subevent 3) is pressed, and cancel when the key is released.
Configuration
In the following example the volume will be set to level 6 when group call 86 is called from stations in UDP group 2. The volume is set to level 3 (default) when the group call is ended.
When stations outside UDP group 2 dial group call 86 this event will not be triggered, and the volume will not be altered.
In AlphaPro, go to Exchange and System -> Events, press Insert and create the following event (the action strings can be copy/paste from here into AlphaPro):
Action commands:
IF %chg(1,0) $DD L%1.dir L85 stop ENDIF $C L%1.dir
Note that in the DAK table of station 164 the DAK key 3 must be blank.
