ABSTRACT:
A system for calling designated addressable notify devices in response to a query to a local telephone company's ALI database system. An advertisement of the 9-1-1-call notification service directs the new subscriber to contact their local telephone provider to register with the new service. The local telephone provider supplies the new system with the registered subscriber's telephone number (ANI) and password. The new subscriber them calls the new service provider directly to register their addressable communication devices to be notified pending a positive reaction to an ALI database system query and the service providers subscriber database. When a registration call is received from a new subscriber, the software proceeds with a voice answerback menu to register numbers to be notified. The notify numbers are stored in a list in a database memory maintained by the notify service. If a call is received from a current subscriber, the software proceeds with a voice answerback menu to update the previously registered numbers to be notified. Subsequently, if a 9-1-1 call is placed from a station that has previously been registered with the service which initiates an ALI database query, the software automatically places a call to each addressable notify device on the subscriber's notify list. If an answer is confirmed, the software transmits a notify message over the telephone or wireless line. The message at least identifies the subscriber's telephone number, and the time and date of the call. If an answer is not confirmed, or the line is busy, the software turns on a "call later" tag associated with the notify number corresponding to the unconfirmed or uncompleted call. Periodically, the software services any tagged, unconfirmed notify calls.
