Abstract

The present invention provides a technique for directly calling telephones via a shared telephone number, which telephones do not have telephone numbers in the address space of the Public Switched Telephone Network. This is particularly useful for visitors and guests who are, for example, temporarily at a hotel, school campus, or business.

Claims

1. A method comprising:

receiving a first call set-up message for a first voice telephone call that has been forwarded from a first originally-called telephone number, wherein said first originally-called telephone number is an address in the address space of the Public Switched Telephone Network; and

attempting to establish a voice telephone call with a first device that has an address outside the address space of the Public Switched Telephone Network;

wherein said address of said first device is found from said first originally-called telephone number.

2. The method of claim 1 further comprising mapping said first originally-called telephone number to said address of said device.

3. The method of claim 1 wherein said device is a telephone extension of a private branch exchange.

4. The method of claim 3 wherein said private branch exchange serves a hotel.

5. The method of claim 1 further comprising:

receiving a second call set-up message for a second voice telephone call that has been forwarded from a second originally-called telephone number, wherein said second originally-called telephone number is an address in the address space of the Public Switched Telephone Network; and

attempting to establish said voice telephone call with said first device;

wherein said address of said first device is found from said second originally-called telephone number.

6. The method of claim 5 wherein said first originally-called telephone number is a residential telephone number and said second originally-called telephone number is a business telephone number.

7. The method of claim 1 further comprising:

receiving a second call set-up message for a second voice telephone call that has been forwarded from a second originally-called telephone number, wherein said second originally-called telephone number is an address in the address space of the Public Switched Telephone Network; and

attempting to establish said second voice call with a second device that has an address outside the address space of the Public Switched Telephone Network;

wherein said address of said second device I found from said second originally-called telephone number.

8. The method of claim 7 wherein said first originally-called telephone number is a first business telephone number and said second originally-called telephone number is a second business telephone number.

9. The method of claim 7 wherein said first originally-called telephone number is a residential telephone number and said second originally-called telephone number is a business telephone number.

10. The method of claim 7 wherein said first originally-called telephone number is a first residential telephone number and said second originally-called telephone number is a second residential telephone number.

11. An apparatus for comprising:

a switch for;

(1) receiving a first call set-up message for a first voice telephone call that has been forwarded from a first originally-called telephone number, wherein said first originally-called telephone number is an address in the address space of the Public Switched Telephone Network and

(2) attempting to establish a voice telephone call with a first device that has an address outside the address space of the Public Switched Telephone Network;

wherein said address of said first device is found from said first originally-called telephone number.

12. The apparatus of claim 11 further comprising a forwarding database for mapping said first originally-called telephone number to said address of said device.

13. The apparatus of claim 11 wherein said device is a telephone extension of a private branch exchange.

14. The apparatus of claim 13 wherein said private branch exchange serves a hotel.

15. The apparatus of claim 11 wherein said switch is also for:

(3) receiving a second call set-up message for a second voice telephone call that has been forwarded from a second originally-called telephone number, wherein said second originally-called telephone number is an address in the address space of the Public Switched Telephone Network; and

(4) attempting to establish said voice telephone call with said first device;

wherein said address of said first device is found from said second originally-called telephone number.

16. The apparatus of claim 15 wherein said first originally-called telephone number is a residential telephone number and said second originally-called telephone number is a business telephone number.

17. The apparatus of claim 11 wherein said switch is also for:

(3) receiving a second call set-up message for a second voice telephone call that has been forwarded from a second originally-called telephone number, wherein said second originally-called telephone number is an address in the address space of the Public Switched Telephone Network; and

(4) attempting to establish said second voice call with a second device that has an address outside the address space of the Public Switched Telephone Network;

wherein said address of said second device I found from said second originally-called telephone number.

18. The apparatus of claim 17 wherein said first originally-called telephone number is a first business telephone number and said second originally-called telephone number is a second business telephone number.

19. The apparatus of claim 17 wherein said first originally-called telephone number is a residential telephone number and said second originally-called telephone number is a business telephone number.

20. The apparatus of claim 17 wherein said first originally-called telephone number is a first residential telephone number and said second originally-called telephone number is a second residential telephone number.
