Abstract

Systems and methods provide foreign call back number compatibility. The systems and methods receive a local telephone number assigned to a subscriber, the subscriber having a non-local telephone number as the normal calling number of the subscriber. Furthermore, the systems and methods query a database with the local telephone number to obtain the non-local telephone number and to provide the non-local telephone number. In addition, systems and methods provide a foreign call back number compatibility database. The systems and methods receive a local telephone number assigned to a subscriber and a non-local telephone number comprising the normal calling number of the subscriber and saving the local number and the non-local number to a database.

Claims

1. A method for providing foreign call back number compatibility, the method comprising:

assigning a non-local telephone number to a subscriber;

assigning a local telephone number to a subscriber; and

providing periodically both the non-local telephone number and the local telephone number associated with the subscriber.

2. The method of claim 1, wherein assigning the local telephone number further comprises assigning the local telephone number to the subscriber comprising a voice-over-internet-protocol subscriber.

3. The method of claim 1, wherein assigning the local telephone number further comprises assigning the local telephone number configured to identify a geographic location of the subscriber.

4. The method of claim 1, wherein assigning the non-local telephone number further comprises assigning the non-local telephone number configured not to identify a geographic location of the subscriber.

5. The method of claim 1, wherein providing periodically further comprises providing periodically to an automatic location information database.

6. A computer-readable medium which stores a set of instructions which when executed performs a method for providing a foreign call back number compatibility database, the method comprising:

assigning a non-local telephone number to a subscriber;

assigning a local telephone number to a subscriber; and

providing periodically both the non-local telephone number and the local telephone number associated with the subscriber.

7. The computer-readable medium of claim 6, wherein assigning the local telephone number further comprises assigning the local telephone number to the subscriber comprising a voice-over-internet-protocol subscriber.

8. The computer-readable medium of claim 6, wherein assigning the local telephone number further comprises assigning the local telephone number configured to identify a geographic location of the subscriber.

9. The computer-readable medium of claim 6, wherein assigning the non-local telephone number further comprises assigning the non-local telephone number configured not to identify a geographic location of the subscriber.

10. The computer-readable medium of claim 6, wherein providing periodically further comprises providing periodically to an automatic location information database.

11. A method for providing foreign call back number compatibility, the method comprising:

receiving a local telephone number assigned to a subscriber, the subscriber having a non-local telephone number as the normal calling number of the subscriber;

querying a database with the local telephone number to obtain the non-local telephone number; and

providing the non-local telephone number.

12. The method of claim 11, wherein receiving the local telephone number assigned to the subscriber further comprises receiving the local telephone number assigned to the subscriber comprising a voice-over-internet-protocol subscriber.

13. The method of claim 11, wherein receiving the local telephone number further comprises receiving the local telephone number configured to identify a geographic location of the subscriber.

14. The method of claim 11, wherein receiving the local telephone number assigned to the subscriber, the subscriber having a non-local telephone number as the normal calling number of the subscriber, further comprises the non-local telephone number configured not to identify a geographic location of the subscriber.

15. The method of claim 11, wherein querying the database further comprises querying the database comprising an automatic location information database.

16. The method of claim 11, wherein querying the database with the local telephone number to obtain the non-local telephone number further comprises querying the database with the local telephone number to obtain the non-local telephone number from a remote call-forwarding field in the database.

17. A system for providing foreign call back number compatibility, the system comprising:

means for receiving a local telephone number assigned to a subscriber, the subscriber having a non-local telephone number as the normal calling number of the subscriber;

means for querying a database with the local telephone number to obtain the non-local telephone number; and

means for providing the non-local telephone number.

18. The system of claim 17, wherein the means for receiving the local telephone number assigned to the subscriber further comprises the means for receiving the local telephone number assigned to the subscriber comprising a voice-over-internet-protocol subscriber.

19. The system of claim 17, wherein the means for receiving the local telephone number further comprises the means for receiving the local telephone number configured to identify a geographic location of the subscriber.

20. The system of claim 17, wherein the means for receiving the local telephone number assigned to the subscriber, the subscriber having a non-local telephone number as the normal calling number of the subscriber, further comprises the non-local telephone number configured not to identify a geographic location of the subscriber.

21. The system of claim 17, wherein the means for querying the database further comprises the means for querying the database comprising an automatic location information database.

22. The system of claim 17, wherein the means for querying the database with the local telephone number to obtain the non-local telephone number further comprises the means for querying the database with the local telephone number to obtain the non-local telephone number from a remote call-forwarding field in the database.

23. A computer-readable medium which stores a set of instructions which when executed performs a method for providing a foreign call back number compatibility database, the method comprising:

receiving a local telephone number assigned to a subscriber, the subscriber having a non-local telephone number as the normal calling number of the subscriber;

querying a database with the local telephone number to obtain the non-local telephone number; and

providing the non-local telephone number.

24. The computer-readable medium of claim 23, wherein receiving the local telephone number assigned to the subscriber further comprises receiving the local telephone number assigned to the subscriber comprising a voice-over-internet-protocol subscriber.

25. The computer-readable medium of claim 23, wherein receiving the local telephone number further comprises receiving the local telephone number configured to identify a geographic location of the subscriber.

26. The computer-readable medium of claim 23, wherein receiving the local telephone number assigned to the subscriber, the subscriber having a non-local telephone number as the normal calling number of the subscriber, further comprises the non-local telephone number configured not to identify a geographic location of the subscriber.

27. The computer-readable medium of claim 23, wherein querying the database further comprises querying the database comprising an automatic location information database.

28. The computer-readable medium of claim 23, wherein querying the database with the local telephone number to obtain the non-local telephone number further comprises querying the database with the local telephone number to obtain the non-local telephone number from a remote call-forwarding field in the database.

29. A method for providing foreign call back number compatibility, the method comprising:

maintaining a database comprising a plurality of local telephone numbers;

associating a one of the plurality of local telephone numbers with a subscriber having a non-local telephone number as a normal calling number; and

providing periodically the non-local telephone number and the one of the plurality of local telephone numbers associated with the subscriber.
