Abstract

A system and method for directing directory assistance calls allows a caller seeking a non-published number to access a voice mail box associated with the non-published number. If a caller calls directory assistance to request a telephone number determined to be non-published, the call may be routed to an automatic recording indicating that the caller may leave a message. The caller may then leave a voice mail message for delivery to the appropriate party.

Claims

1. A method for delivering a message to a voice mail box of a listed party with a non-published directory number comprising the steps of:

receiving a directory assistance call from a caller to a destination;

determining that the destination is a non-published directory number;

determining whether a voice mail box is associated with the non-published directory number;

routing the call to the associated voice mail box; and

screening the call to determine if the caller is eligible to use message delivery.

2. The method of claim 1 wherein the step of determining whether a voice mail box is associated with the non-published directory number includes the step of

checking a directory assistance database for an indicator to determine whether to route messages for the listed party to the associated voice mail box.

3. The method of claim 1 wherein the receiving step includes the steps of receiving the directory assistance call at a local switch;

directing the directory assistance call to an operator services switch;

connecting the directory assistance call to an operator through the operator services switch;

receiving information from the caller identifying a listed party; and

accessing a database to retrieve the listed party'"'"'s number based on the information.

4. The method of claim 1 wherein the step of determining that the destination is a non-published directory number includes the step of

receiving from a directory assistance database an indication that the requested number is non-published.

5. The method of claim 1 wherein the routing step includes the steps of

reading from a database a number to a voice mail system associated with the non-published number;

and

accessing the voice mail box using the number to the voice mail system and the non-published number.

6. The method of claim 5 wherein the accessing step includes the step of

transmitting the non-published number and the voice mail system number to a services computer to access the voice mail box associated with the listed party.

7. The method of claim I further including the step of

maintaining billing information.

8. The method of claim 7 wherein the maintaining step includes the step of

providing an operator services switch with billing information.

9. The method of claim 7 wherein the maintaining step includes the step of providing an operator services switch with information indicating a type of service provided.

10. A method for delivering a message to a voice mail box of a listed party with a non-published directory number comprising the steps of:

receiving a directory assistance call from a caller to a destination;

determining that the destination is a non-published directory number;

determining whether a voice mail box is associated with the non-published directory number;

routing the call to the associated voice mail box; and

monitoring the call to the voice mail box for evidence of fraud.

11. A system for delivering a message to a voice mail box of a listed party with a non-published directory number, comprising

means for receiving a directory assistance call from a caller to a destination;

means for determining that the destination is a non-published directory number;

means for determining whether a voice mail box is associated with the non-published directory number;

means for routing the call to the associated voice mail box; and

means for screening the call to determine if the caller is eligible to use message delivery.

12. The system of claim 11 wherein the means for determining whether a voice mail box is associated with the non-published directory number includes

means for checking a directory assistance database for an indicator to determine whether to route messages for the listed party to the associated voice mail box.

13. The system of claim 11 wherein the receiving means includes

a local switch;

an operator services switch linked to the local switch and to an operator;

a directory assistance database linked to the operator and to the operator services switch;

means for receiving information from the caller identifying a listed party; and

means for accessing the directory assistance database to retrieve the listed party'"'"'s number based on the information.

14. The system of claim 11 wherein the means for determining that the destination is a non-published directory number includes

means for receiving from a directory assistance database an indication that the requested number is non-published.

15. The system of claim 11 wherein the routing means includes

means for reading from a database a number to a voice mail system associated with the non-published number;

and

means for accessing the voice mail box using the number to the voice mail system and the non-published number.

16. The system of claim 15 wherein the accessing means includes

means for transmitting the non-published number and the voice mail system number to a services computer to access the voice mail box.

17. The system of claim 11 further including

means for maintaining billing information.

18. The system of claim 17 wherein the maintaining means includes

means for providing an operator services switch with billing information.

19. The system of claim 17 wherein the maintaining includes means for providing an operator services switch with information indicating a type of service provided.

20. A system for delivering a message to a voice mail box of a listed party with a non-published directory number, comprising

means for receiving a directory assistance call from a caller to a destination;

means for determining that the destination is a non-published directory number;

means for determining whether a voice mail box is associated with the non-published directory number;

means for routing the call to the associated voice mail box; and

means for monitoring the call to the voice mail box for evidence of fraud.

21. A services computer for delivering a message to a voice mail box of a listed party with a non-published directory number comprising the steps of:

means for obtaining a non-published dialed number and an associated voice mail system number;

means for accessing a voice mail system according to the voice mail system number;

means for accessing a voice mail box according to the non-published dialed number;

means for establishing a connection between a caller and the accessed voice mail box; and

means for monitoring the connection for evidence of fraud.

22. The services computer of claim 21 further including

means for reporting billing information to an operator services switch.

23. In a system for delivering a message to a voice mail box of a listed party with a non-published directory number, a database comprising:

a list of names;

a phone number associated with each name in the list;

a first flag indicating whether the phone number is non-published; and

a second flag associated with each non-published number indicating whether to route messages to an associated voice mail box a third flag indicating whether a caller is eligible to use message delivery.
