The 999 Lockout Notification on Mitel phone systems allow an ONS CLASS extension to be programmed for 999 notifications. The 999 caller's name and number is identified on the display.

This Mitel phone system application is ideal for after-hours operation, when the attendant or sub-attendant is not at the desk. For example, in hotels for security guards, or in hospital applications when the on-duty personnel is away from their desks, they can still be notified of lockout alarms and/or 999 calls, with the use of an ONS/CLASS portable display telephone.
