Abstract

Abstract A system and method for providing directory information with a call completion feature includes a data network server located on a data network for establishing a connection between a first communication device and a second communication device. The network server is configured to transmit a search command signal in response to a search command request and to transmit an establish-connection command signal in response to an establish-connection request, the establish-connection command signal being necessary to establish the connection between the first and second communication devices. A database is connected to the network server and is configured to transmit a first telephone number to the server in response to the search command signal. In a preferred embodiment, the establish-connection command signal is transmitted to a computer connected to the server, causing the computer to dial the first telephone number, thereby establishing the connection between the first and second communication devices. In another preferred embodiment, the establish-connection command signal is transmitted from the server to a telephone switch, causing the telephone switch to establish the connection between the first and second communication devices. In alternative embodiments, the system may be implemented over an internet protocol (IP) telephony connection or via any known network.

Claim 5
Dependent Claim 115 words
The system of claim 1 wherein said server is connected to a computer via said data network, said computer being said requesting source, said connection being configured to relay said search request and said establish-connection request from said computer to said server, and further wherein said establish-connection command signal transmitted from said server includes said first telephone number assigned to said first communication device and instructions directing said computer to establish said connection between said first communication device and said second communication device based upon said first telephone number, said first communication device being a first telephone remotely located from said computer and said second communication device being a second telephone connected to said computer.
Claim 6
Independent Claim 135 words
A method for providing telephone directory information comprising the steps of: receiving a data transmission from a computer via a data network, including receiving a search request for a first telephone number assigned to a first communication device; accessing said telephone number from a generally accessed telephone directory database; transmitting data related to said telephone number accessed from said database to said computer via said data network; transmitting a command to said computer via said data network to establish a telephonic connection that includes said first communication device, said first communication device being remotely located from said computer, said command being specific to said telephone number; and establishing said telephonic connection involving said first communication device as a response to said command to establish said connection, including utilizing said computer in initiating said telephonic connection.
