  • Patent number: 6594352
    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.

  • Patent number: 6381325
    Abstract: A method of providing wireless directory assistance service includes the steps of receiving a call placed by a caller at a telecommunications carrier switch, routing the call to a call management platform coupled to the telecommunications carrier switch. A directory assistance service provider is contacted via the telecommunications carrier switch or via a frame relay network. The call is then split from the call to the directory assistance service provider. The call management platform then receives a destination number from the directory assistance service provider and supplies it to the caller in a voice announcement. The destination number may be received in-band or via the frame relay network. The call management platform waits a predetermined time period and then automatically connects the call to the destination number via the telecommunications carrier switch if the call has not been disconnected within the predetermined time period.
