A mobile telephone, or personal communication services subscriber who wishes
directory assistance services is connected in the conventional manner to an operator who identifies a destination
telephone number desired by the subscriber. As known in the prior art, the operator then initiates a call connecting the subscriber to the destination
telephone number. In a preferred embodiment, the operator locates a desired destination
telephone number in a
computer database, and can select automatic dialing of the located number. Further, rather than dropping all further involvement with the call, the preferred embodiment of the present invention continually monitors the connection thereby established for a predetermined DTMF
signal issued by the customer, such as that obtained by pressing the “★” button. If such a
signal is detected, the customer is transferred to a
directory assistance operator, who can then provide whatever further assistance is needed (e.g., providing further
directory assistance). If a busy
signal or non-answering party is detected, a customer is given a plurality of options including leaving a recorded message or page, or a predetermined
alphanumeric message or page for the called party. In this case, the
system automatically tries, repeatedly, to deliver the recorded message or page and, optionally, confirms successful or failed
message delivery to the calling party.
