Abstract

A method and apparatus for reducing the cost of long distance phone calls is disclosed. Accordingly, an originating phone network is operatively connected to a first intermediate point, and a receiving phone network is operatively connected to a second intermediate point. Each intermediate point is operatively connected to communicate via a data network. Users on the originating and destination phone networks may communicate based on virtual numbers. The virtual number is preferably within the local calling area of the originating phone network. The first and second intermediate points route calls to any geographic location, regardless of distance, over the data network based on the virtual number. This provides the advantage of allowing a user on the originating phone network to access a user at a distant location for a price that is substantially similar to the price of a local call.

Claims

1. A method for transmitting information between two or more points, comprising:

receiving a virtual number at a first intermediate point from at least one originating point, the at least one originating point operatively connected to an originating network, and the first intermediate point operatively connected to a packet-based network;

convening the virtual number into at least one physical number;

determining a second intermediate point based on the at least one physical number, the second intermediate point operatively connected to the packet-based network;

determining at least one destination point based on the at least physical number; and

transmitting information between the at least one originating point and the at least one destination point via the first and second intermediate point;

wherein the originating network is selected from the group consisting of;

the public switched telephone network and a packet-based network.

2. The method according to claim 1, wherein the receiving comprises establishing a communication path via a router between the first intermediate point and the at least one originating point.

3. The method according to claim 2, wherein the converting further comprises:

interpreting the virtual phone number at the router;

communicating with a routing table, and;

determining the physical number from the routing table.

4. The method according to claim 3, wherein the determining at least one destination point further comprises:

selecting a destination router based on the routing table;

determining routing instructions corresponding to the destination router based on the routing table; and

establishing a communication path between the router and the destination router.

5. The method according to claim 4, wherein the destination router is in a local calling area of the at least one destination point.

6. The method according to claim 1, wherein the receiving comprises establishing a communication path via an analog-to-digital converter between the first intermediate point and the at least one originating point.

7. The method according to claim 6, wherein the converting further comprises converting analog voice data into packets using a standard network protocol.

8. The method according to claim 7, wherein the standard network protocol is Internet Protocol.

27. The method of claim 1, wherein the information is voice.

9. A method for transmitting information between two or more points, comprising:

receiving a virtual number at a first intermediate point from at least one originating point, the first intermediate point operatively connected to a packet-based network;

converting the virtual number into at least one physical number,

determining a second intermediate point based on the at least one physical number, the second intermediate point operatively connected to the packet-based network;

determining at least one destination point based on the at least one physical number; and

transmitting information between the at least one originating point and the at least one destination point via the first intermediate point and the second intermediate point;

wherein the at least one destination point is operatively connected to a network selected from the group consisting of;

a public switched telephone network and a packet-based network.

10. The method according to claim 9, wherein the determining at least one destination point comprises establishing a communication path via a router between the at least one destination point and the second intermediate point.

11. The method according to claim 10, wherein the determining at least one destination point further comprises:

communicating with a routing table;

selecting the router based on the routing table;

determining routing instructions corresponding to the router based on the routing table, and

establishing a communication path between the first intermediate point and the router.

12. The method according to claim 11, wherein the router is in a local calling area of the at least one destination point.

13. The method according to claim 9, wherein the determining at least one destination point comprises establishing a communication path via a digital-to-analog converter between the at least one destination point and the second intermediate point.

14. The method according to claim 13, wherein the transmitting comprises converting packets into analog voice data using the digital-to-analog converter.

15. A System for transmitting information across a computer network, comprising:

a first intermediate point operatively connected to an originating network including at least one originating device;

a second intermediate point operatively connected to a destination network including at least one destination device;

said first intermediate point comprising first means for receiving a virtual number from, the originating network;

converting the virtual number into at least one physical number;

selecting the second intermediate point based on the second intermediate point'"'"'s proximity to the destination device;

converting voice data received from the originating network into data packets; and

transmitting data packets to a computer network;

said second intermediate point comprising second means for receiving said data packets from the computer network, converting data packets into voice data and placing voice data on the destination network for transport to the destination device; and

,

said first intermediate point and said second intermediate point operatively connected to each other via the computer network.

16. The system according to claim 15, wherein the at least one physical number comprises a country code, wherein the country code is outside a local calling area of the at least one originating device and within a local calling area of the at least one destination device.

17. The system according to claim 15, wherein the second intermediate point is within the local calling area of the at least one destination device.

18. The system according to claim 15, further comprising a memory operatively connected to the first and second intermediate points, wherein the memory stores an assignment of the virtual number to the second intermediate point, the at least one physical number and the at least one destination device.

19. The system according to claim 18, wherein the memory is a routing table.

20. The system according to claim 15, wherein the first and second intermediate points comprise routers.

21. The system according to claim 20, wherein the first and second intermediate point routers are accessible to a plurality of virtual numbers.

22. The system according to claim 15, wherein information is transmitted over the computer network based on packets.

23. The system according to claim 15, wherein information is transmitted to and from the originating and destination devices as analog signals.

24. The system according to claim 15, wherein the first and second intermediate points comprise means for analog-to-digital conversion and digital-to-analog conversion.

25. The system according to claim 15, wherein the at least one originating device and the at least one destination device comprise telephones operatively connected to the public switching telephone network.
