Abstract

A telephone network capable of handling directory assistance calls includes a switch, connection circuitry coupled between the switch and a directory assistance center, and call origination circuitry. In response to receipt of a incoming directory assistance call from the switch, the connection circuitry connects the incoming directory assistance call to the directory assistance center. Following receipt of a requested telephone number from the directory assistance center, the call origination circuitry originates an extension call to the requested telephone number on the public telephone network and transmits, in conjunction with the extension call, at least a billing identifier captured from the incoming directory assistance call. In this manner, the switch is able to automatically associate the extension call with the billing identifier captured from the incoming directory assistance call.

Claims

call origination circuitry coupled to said connection circuitry that, following receipt of a telephone number from the directory assistance center, originates an extension call to said telephone number through a switch of the public telephone network and transmits to said switch, in conjunction with said extension call, at least a billing identifier captured from said incoming directory assistance call, wherein said call origination circuitry, after originating said extension call, releases said extension call to said public telephone network, such that said extension call and said incoming directory assistance call are connected together by said public telephone network independently of said apparatus and said apparatus is no longer involved in the connected call.

7. The apparatus of claim 6, wherein said call origination circuitry originates said extension call only in response to receipt of caller authorization via said incoming directory assistance call.

8. The apparatus of claim 6, wherein said connection circuitry is connectable between a switch of the directory assistance center and a switch of the public telephone network.

11. The apparatus of claim 6, wherein said apparatus comprises a computer system.

20. The apparatus of claim 6, and further comprising the directory assistance center.

21. The apparatus of claim 20, said directory assistance center including a switch and having a telephone number database.

25. The apparatus of claim 6, wherein the call origination circuitry originates the extension call through an inter-exchange carrier switch.

9. An apparatus for handling directory assistance calls in a public telephone network, said apparatus comprising:

connection circuitry, connectable between a switch of a public telephone network and a switch of a directory assistance center, that connects an incoming directory assistance call received from the public telephone network to the directory assistance center via a non-dedicated line; and

call origination circuitry coupled to said connection circuitry that, following receipt of a telephone number from the directory assistance center, originates an extension call to said telephone number through a switch of the public telephone network and transmits to said switch, in conjunction with said extension call, at least a billing identifier captured from said incoming directory assistance call, wherein said call origination circuitry, after originating said extension call, releases said extension call to said public telephone network, such that said extension call and said incoming directory assistance call are connected together independent of said apparatus.

10. The apparatus of claim 9, wherein:

said at least one connection can convey both voice and data; and

said apparatus receives said telephone number and billing information related to said extension call from said directory assistance center via said at least one connection.
