A button set to this function indicates when a call has been made using a number in the system's Emergency Numbers list. Pressing the button displays a list of such calls.

The button flashes when an emergency call is in progress. It is on when there are previous emergency calls in the call log.

Pressing the button displays details of any emergency call is progress (up to 10). The History option displays details of previous emergency calls (up to 30) and allows deletion of previous call details.

If an extension already has a button set to this function, creating another button with this function will automatically clear the setting from the existing button.

This function is only supported on a button that includes LED/LCD indicator. The indicator is lit when the function is enabled.

Not supported on ETR6 and 1403 phones. Not supported on BST phones.
