  • 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.
