Abstract

Integrated Devices enable the integration of the Internet with the Public Switched Telephone Network (PSTN). A device can place a telephone call to an Integrated Device via dialing on the PSTN and have the call consummated over the Internet via a mechanism of messaging between the associated devices and systems.

Claims

1. A computerized terminal device for conducting audible and visual communications over the Internet that originated as a call dialed on the PSTN, comprising:

(a) control logic for initiating or receiving an integrated Internet and telephony call, wherein a call dialed on the PSTN consummates on the Internet;

(b) Internet connectivity associated with an Internet Protocol (IP) address, or a surrogate, proxy, agent, or other substitute for said IP address, said IP address either permanently or dynamically assigned;

(c) means for PSTN connectivity, said connectivity having an associated telephone number, and said connectivity providing means to carry digital call control messages;

(d) digital messaging means for sending digital call control messages to the PSTN and receiving digital call control messages therefrom, said messages to incorporate telephone numbers and IP addresses.

2. A device as recited by claim 1 further comprising control logic for conducting any or all portions of said consummated communication over the Internet.

3. A device as recited by claim 1 which does not have a display screen for visual communications with other devices.

4. A device as recited by claim 1 wherein said digital messaging means to send and receive digital call control messages is compatible with ISDN.

5. A device as recited by claim 1 wherein said digital messaging means to send and receive digital call control messages is compatible with ADSI.

6. A device as recited by claim 1 wherein said digital messaging means to send and receive digital call control messages is compatible with the Internet Protocol.

7. A device as recited by claim 1 wherein said Internet connectivity and said PSTN connectivity are provided by wireless means.

8. A device as recited by claim 1 wherein said PSTN connectivity means is a DSL connection.

9. A device as recited by claim 8 wherein said Internet connectivity means is said DSL connection.

10. A device as recited in claim 1 wherein said PSTN connectivity means is a cable-TV connection.

11. A device as recited in claim 10 wherein said Internet connectivity means is said cable-TV connection.

12. A device as recited in claim 1 wherein said PSTN connectivity means is an ISDN connection.

13. A device as recited in claim 12 wherein said Internet connectivity means is said ISDN connection.

14. A device as recited in claim 1 further comprising means to place telephone calls to analog telephone devices and to receive telephone calls from analog telephone devices.

19. A device as recited by claim 18, further comprising control logic for conducting any or all portions of said consummated communication over the Internet.

20. A device as recited by claim 19, wherein said computerized terminal device is a Personal Computer (PC), and said control logic is a software application operating on said PC.

15. A method of operation of a computerized terminal device for conducting audible and visual communications over the Internet that originate as a call dialed on the PSTN, comprising the steps of:

(a) sending a digital PSTN call setup request message to the PSTN by a calling device, said message to include a telephone number of a called device;

(b) receiving a digital PSTN call setup response message from the PSTN, said response message to include the IP address of said called device; and

(c) sending an Internet call setup request message over the Internet by said calling device to said called device, said Internet call setup request message having the IP address of said called device as the IP destination address.

16. A method of operation of a computerized terminal device for conducting audible and visual communications over the Internet that originate as a call dialed on the PSTN, comprising the steps of:

(a) sending a digital PSTN call setup request message to the PSTN by a calling device, said message to include a telephone number of a called device;

(b) receiving a digital PSTN call setup message from the PSTN by said called device, said message to include the IP address of said calling device; and

(c) sending an Internet call setup request message over the Internet by said called device to said calling device, said Internet call setup request message having the IP address of said calling device as the IP destination address.

17. A method of operation of a computerized terminal device for conducting audible and visual communications over the Internet that originate as a call dialed on the PSTN, comprising the steps of:

(a) sending a digital PSTN call setup request message to the PSTN by a calling device, said message to include a telephone number of a called device;

(b) establishing a messaging channel by the PSTN between said calling and said called devices;

(c) sending a message via said PSTN messaging channel containing the sending device'"'"'s IP address by a first one of said calling and called devices to a second one of said calling and called devices; and

(d) sending an Internet call setup request message over the Internet by said second one of said calling and called devices to said IP address of said first one of said calling and called devices.

18. A computerized terminal device for conducting audible and visual communications over the Internet that originated as a call dialed on the PSTN, comprising:

(a) Internet connectivity associated with an IP address, or a surrogate, proxy, agent, or other substitute for said IP address, said IP address either permanently or dynamically assigned;

(b) control logic for initiating an integrated Internet and telephony call, wherein a call dialed on the PSTN consummates on the Internet, said call being conducted using a Voice over IP arrangement; and

(c) digital messaging means for sending and receiving digital call control messages to and from the PSTN via said Voice over IP, said call control messages incorporating telephone numbers and IP addresses.

21. A method of operation of a computerized terminal device for conducting audible and visual communications over the Internet that originate as a call dialed on the PSTN, comprising the steps of:

(a) sending a digital VoIP call setup request message via the Internet to a VoIP interface device, said message to include the IP address of said terminal device, and a telephone number of a called device;

(b) receiving a digital VoIP call setup response message from said VoIP interface device, said response message to include the IP address of said called device; and

(c) sending an Internet call setup request message over the Internet to said called device, said Internet call setup request message having the IP address of said called device as the IP destination address.
