Group Call - Increased volume
From Zenitel Wiki
This article describes how to increase the volume of the gong signal, and set it back to normal when the group call is answered (or canceled).
As from firmware version AMC 10.23 the volume to a station can be changed by the data command VOL. By using 4 events the Event Handler, one can set a higher volume during the gong signal, and set it back to a normal level when the call is answered.
In the following example a door station (101) is making a group call with repeatative gong to group 4. The members in group 4 also needs to be members of UDP group 7. In AlphaPro, go to Exchange and System -> Events, press Insert and create the following event:
| Event Owner: | Station Id: Id: 1 (101 The Door) |
| Event type: | 15 - Event Trigger Feature |
| When change to: | ON |
| When related to: | Id: 9534 |
| Action: | WUDD 2 0 |
| $ER U15 U1 U1 U1 L101 U3 L9001 |
When a station starts to ring the volume is set to level 6, and when the ringing stops the volume is set to level 3.
