Internet switch box, system and method for internet telephony
First Claim
1. A method of establishing a telephony call, comprising:
- associating a telephone number provided by a first terminal with a first Internet protocol (IP) address;
establishing an Internet communication link in a communication path between the first terminal and a second terminal using the associated first IP address;
communicating information across the established Internet communication link;
associating a telephone number provided by the second terminal with a second IP address, wherein;
the Internet communication link is established using the first and second IP addresses,communicating the telephone numbers provided by the first and second terminals to an IP server, wherein;
the IP server associates the respective telephone numbers with the first and second IP addresses and enables the establishment of the Internet communication link based on the first and second IP addresses;
communicating the second IP address, provided by a first device interconnecting the first terminal with a first network connection of the Internet communication link, to the IP server; and
communicating the first IP address, provided by a second device interconnecting the second terminal with a second network connection of the Internet communication link, to the IP server, wherein;
the IP server associates the telephone number provided by the first terminal with the first IP address provided by the second device and associates the telephone number provided by the second terminal with the second IP address provided by the first device.

Abstract
An Internet switch box connects between a telephone set and a public switched telephone network (PSTN) line, the latter of which is used both for PSTN telephone conversations and for connection to an Internet service provider (ISP). The switch box contains hardware and embedded software for establishing a connection to an ISP and for Internet telephony. When two users, each having an Internet switch box connected to the telephone set, wish to have an Internet telephony conversation, one calls the other over the PSTN. When they agree to an Internet telephony conversation, they signal their Internet switch boxes, by pressing either buttons on the switch boxes or certain keys on the telephone keypads, to switch to Internet telephony. The switch boxes disconnect the PSTN call and connect to their ISPs. Once the switch boxes are on the Internet, they contact each other through a server which supplies Internet protocol (IP) addresses of switch boxes, and the users continue their conversation by Internet telephony. The users can also prearrange to call each other solely by Internet telephony, in which case they do not need to talk to each other over the PSTN.

3. A system for establishing a telephony call, comprising:
-
an internet switch box (ISB) terminal and a second terminal; an Internet protocol (IP) server that associates a telephone number provided by the ISB terminal with a first IP address; and first and second devices, in a communication path between the ISB terminal and the second terminal, that establish an Internet communication link using the associated first IP address and communicate information across the established Internet communication link, wherein; the IP server associates a telephone number provided by the second terminal with a second IP address; the first and second devices establish the Internet communication link using the first and second IP addresses; the ISB terminal and the second terminal communicate the respective telephone numbers to the IP server; the IP server associates the respective telephone numbers with the first and second IP addresses and enables the establishment of the Internet communication link based on the first and second IP addresses; the first device communicates the second IP address to the IP servers; the second device communicates the first IP address to the IP server; and the IP server associates the telephone number provided by the ISB terminal with the first IP address provided by the second device and associates the telephone number provided by the second terminal with the second IP address provided by the first device.

4. A system of establishing a telephony call, comprising:
-
first and second Internet service box terminals; an Internet protocol (IP) server that; correlates a first destination telephone number provided by the first ISB terminal with a first origination telephone number provided by the second Internet service box terminal to associate a first Internet protocol (IP) address with the first destination telephone number; and correlates a second destination telephone number provided by the second ISB terminal with a second origination telephone number provided by the first Internet service box terminal to associate a second IP address with the second destination telephone number; and first and second devices, in a communication path between the first and second Internet service box terminals, that establish an Internet communication link using the associated first and second IP addresses and communicate information across the established internet communication link, wherein; the first device communicates the second IP address, of a first network connection of the Internet communication link, to the IP server; and the second device communicates the first IP address, of a second network connection of the Internet communication link, to the IP server, wherein the IP server associates the first destination telephone number provided by the first terminal with the first IP address provided by the second device and associates the second destination telephone number provided by the second terminal with the second IP address provided by the first device.
