Abstract

Disclosed is a method and apparatus for establishing anonymous telephone communications between service subscribers and responding callers over public telephone lines controlled by a public telephone company central switching office having the capability of interlinking select public telephone lines. Communications between the subscribers and responding callers can be performed with complete confidentiality and mutual anonymity. Incoming calls from callers are transferred by a system controller and an additional subsystem to a message recording facility or directly to the desired subscriber. When a call is transferred directly to a subscriber, the static connection is made and maintained by the public telephone company'"'"'s central switching office, and the system controller is disconnected from both caller and subscriber.

Claims

1. A telephone communication method for anonymously connecting a subscriber station and a caller station via public telephone lines controlled by a public telephone company central switching station having the capability of connecting together select ones of the public telephone lines, the method including the steps of:

storing data at a system controller station that is received from a plurality of subscriber stations, such data including the telephone number of each subscriber station and a corresponding reference number for each subscriber station;

publishing the telephone number of said system controller station in advertisements including the reference numbers for the respective subscriber stations;

receiving a call from a caller station to said system controller station;

receiving a published reference number from said caller station in communication with said system controller station;

matching said received published reference number with the telephone number of the corresponding subscriber station;

automatically connecting the telephone call received from said caller station at the system controller station to said corresponding subscriber station, said connecting being accomplished at said public telephone company central switching station, under the control of said system controller station; and

disconnecting said system controller station from the caller station, the subscriber station, and the public telephone company central switching station, so that after said caller station and said subscriber station are connected together on their respective public telephone lines, the public telephone company central switching station maintains the connection between the caller and subscriber stations.

2. The method of claim 1 and further including the step of storing call transferring instructions as programmed by each subscriber station.

3. The method of claim 1 and further comprising the step of recording a message from said caller station if said corresponding subscriber station is unavailable to receive a call, such recorded message including a call back reference number of said caller station that is indexed to a stored telephone number of said caller station.
