Timeout of conversation (Event Handler)
From Zenitel Wiki
Using the $ST (Set_Timer) message.
Timeout of incoming calls to one specific station:
In AlphaPro, go to Exchange and System -> Events, press Insert and create the following events:
Event 1
Action commands:
$ST L%1.dir w%chg(1800,0) L%2.dir
Event 2
Action commands:
$C L%1.dir
If the conversation timeout should apply for outgoing calls as well, add the following events:
Event 3
Action commands:
$ST L%1.dir w%chg(1800,0) L%2.dir
If the timeout should apply to a number of stations the easiest way is to assign the stations concerned to a UDP group, and then set the UDP group as Event Owner instead of the 'The station' in the above events.
