A button set to this function indicates when a call has been made from the system to which the user’s extension is registered. The definition of an emergency call is one using a number routed by a Dial Emergency button or short code.
Pressing the button displays details of currently connected emergency calls (the first 10).
After pressing the button, the History option displays details of any previously connected emergency calls (the first 30) and allows deletion those call details.
The emergency call history for a system is shared by all users on the same system. Therefore updates to or deleting the history affects the details shown on all user phones on the same system.
The time shown in the call details, is the UTC time of the alarm calls. On J189 phones, it also includes the location name if an IP Office Location entry was used to route the call.
Note that the button only works for an extension registered to the same system as the outgoing trunk used for the emergency call.
