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.
