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.
