2-2e. Event Trigger - Event Handler (solution)
From Zenitel Wiki
Solution
Call setup:
- The Entrance and the SOS Point should be configured to make a Call Request (623 + 101) to the Control Room.
- The Control Room should be configured as a CRM (Control Room Master), the DAK display should be enabled, and the Navigation Keys should be used for call queue navigations.
Toggle Call Request Forwarding:
- When dialing the event trigger number 9533, or when pressing a DAK key programmed to 9533 on the Control Room station, the following features should be toggled ON/OFF every time the number is activated:
- Turn on/off Call Request Forwarding from Control Room station 101 to station 103 (M. Larsen), so that all new call requests will be forwarded to station 103. Use the command "$SCRT" for this.
- Turn on/off a lamp (use RCO 3) to signal that call forwarding is active
- Write to the System LOG that the call forwarding has been activated/turned off. Use the LOG "..." statement.
The full action string is:
IF %udd(1) If Call Forwarding is active (UDD 1 different from 0") $SCRT L101 Turn off Call Forwarding at 101 RCO 3 OFF Turn off RCO 3 LOG "Control Room: Call Forwarding turned off" Send info to System log WUDD 1 0 Set new status = Call Forwarding not active (UDD 1 = 0) STOP Don't execute the rest of the actions ENDIF If Call Forwarding is not active (UDD 1 = 0) $SCRT L101 L103 Turn on Call Forwarding at 101 RCO 3 ON Turn on RCO 3 LOG "Control Room: Call Forwarding active" Send info to System log WUDD 1 1 Set new status = Call Forwarding active (UDD 1 = 1)
Program DAK 1 of the Control Room station with the code for Call Forwarding on/off (9533), and add an appropriate display text.
Verify that:
- Call Forwarding is toggled on and off
- RCO 3 is toggled on and off
- The Call forwarding on/off is logged in the "System Log" (AlphaWeb: System Monitoring -> Logging. It might be that logging has to be enabled first: System Configuration -> Logging).
