If one of your user calls an emergency service, someone for e.g. the front desk or receptionist of the building should get the caller information. So when the emergency personnel arrives, receptionist can use the caller information and identify the user. You can set up Communication Manager to alert the attendant and up to ten other extensions whenever an end-user dials an emergency number. The display on the receptionist's telephone shows the name and the number of the person who placed the emergency call. The telephone also ring with a siren-type alarm, which receptionist must acknowledge to cancel.
Note:
You must decide if you want one user to be able to acknowledge an alert, or if all users must respond before an alert is canceled. Verify that the ARS field is y on the System Parameters Customer-Options (Optional Features) screen.
Ensure that the extensions you notify belong to physical digital-display telephones. When you assign crisis alert buttons to the telephones, check the Type field on the Station screen to be sure you are not using a virtual extension.
Refer to Telephone Reference for a list of telephone types.
