Call restriction from guard station to cell station (Event Handler)

Situation

Calls from the guard station to the cell stations should be rejected unless the cell has made a Call Request to the guard.

Solution

Use the event type “Call Requester Mode” on the cell stations to set/reset call forwarding to a 'dummy' (non-existing) subscriber.

• The text of the 'dummy' subscriber could be ‘Rejected’.
• Number of rings on call forwarding should be set to 0. Go to [[Exchange_&_System_(AlphaPro)#Calls_and_Options|Exchange & System -> System -> Calls and Options and set Call Forwarding – Ringing Count to 0.
• Feature Reminder (blink’n bleep) should be disabled for the cells. Go to [[Users_&_Stations_(AlphaPro)#User_Preferences|Users & Stations -> User Prefernces and tick off Feature Reminder.

In AlphaPro, go to Exchange and System -> Events, press Insert and create the following events:

---

Event 1 - Set transfer to 'dummy' number 345 when not in Call Requester Mode.

Event Owner:	Stations w/UDP, Id: 2 (All cell stations)
