Abstract

A central location of a telephone switching system is placed where favorable local exchange tariffs are available. The central location includes a caller responsive unit which compares the caller identification accompanying the call attempt against a prestored list of identification data assigned to authorized system users. The system then calls the originating caller telephone from the central location. The system allows the originating caller to input the number of the party to whom a connection is desired by the originator. The system establishes a connection with the called party and bridges communications between the called and calling parties at the central location. The system includes the capability of employing audio responses of various types to calling or called parties.

Claims

1. A system for establishing a communication link between a subscriber station and a destination station, both being connected through a network comprising:

control means operable for managing a database of caller information;

storage means connected to the control means and operable for storing the database of caller information including a preassigned signal associated with a subscriber and a subscriber call-back number associated with the subscriber telephone station;

first connection means connected to the control means and operable for receiving an incoming signal as part of an incoming call attempt from the subscriber telephone station;

second connection means connected to the control means and operable for establishing a communication path;

the control means further operable for comparing the incoming signal to the preassigned signal and, if the incoming signal matches the preassigned signal associated with the subscriber, the control means is further operable for;

calling the subscriber through the outbound path;

receiving from the subscriber a calling number for the destination station;

calling the destination number through the second outbound path; and

for bridging the path to the second path so that the subscriber is connected to the destination.

2. A system as in claim 1 wherein the preassigned signal associated with the subscriber is a means to (a) identify the subscriber and (b) to ascertain the stored subscriber call-back number.

3. A system as in claim 2 wherein the means to identify the subscriber and to ascertain the call-back number is a direct inward dial number.

4. A system as in claim 2 wherein the means to identify the subscriber and to ascertain the call-back number is a signal through a packet switched network.

5. A system as in claim 4 wherein the packet switched network is based on Internet Protocol.

6. A system as in claim 4 wherein the packet switched network is X.25.

7. A system as in claim 4 wherein the packet switched network is X.400.

8. A system as in claim 4 wherein the packet switched network is Frame Relay.

9. A system as in claim 2 wherein the means to identify the subscriber and to ascertain the call-back number is a signal via a cable television network.

10. A system as in claim 2 wherein the means to identify the subscriber and to ascertain the call-back number is an optical network.

11. A system as in claim 2 wherein the means to identify the subscriber and to ascertain the call-back number is a radio frequency network.

13. A method as in claim 12 wherein the step of receiving the preassigned signal associated with the subscriber is via a direct inward dial number sent from the subscriber through the public switched telephone network.

14. A method as in claim 12 wherein the step of receiving the preassigned signal associated with the subscriber is via a packet switched network.

15. A method as in claim 13 wherein the packet switched network is X.25.

16. A method as in claim 13 wherein the packet switched network is X.400

17. A method as in claim 13 wherein the packet switched network is based on Internet Protocol.

18. A method as in claim 14 wherein the packet switched network is Frame Relay.

19. A method as in claim 12 wherein the step of receiving the preassigned signal associated with the subscriber is via an optional network.

20. A method as in claim 12 wherein the step of receiving the preassigned signal associated with the subscriber is via a cable TV network.

21. A method as in claim 12 wherein the step of receiving the preassigned signal associated with the subscriber is via a radio frequency network.

12. A method establishing a communication link between a subscriber and a destination comprising the steps of:

storing a preassigned signal associated with a subscriber;

storing a subscriber call-back number associated with the subscriber station;

receiving an incoming signal as part of an incoming call attempt from the subscriber telephone station;

comparing the incoming signal to the preassigned signal and if the incoming signal matches the preassigned signal associated with the subscriber, performing the following steps;

calling the subscriber on a first outbound path and connecting to the subscriber station;

receiving from the subscriber a calling number for the destination station;

calling the destination number through a second outbound path; and

bridging the first connection to the second connection so that the subscriber is connected to the destination.
