Multiple phones are used by on-call staff and are not assigned to specific staff due to rotating schedules. An ability to use the same authorization code or an ability to disable the authorization code feature is needed, so that staff are aware of what authorization code to use no matter what phone they are being assigned that day. Using the same authorization code was available in previous versions of the Win-911 and standard operating procedures have been developed and adopted with that in mind. It was not anticipated that a change in operating procedure and the associated costs would be required with the Win-911 upgrade.
