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

1-33. -33. (canceled)

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

assigning a non-local, packet switched telephone number to a subscriber, the non-local, packet switched telephone number comprising a callable telephone number;

assigning a local telephone number to a subscriber that is associated with the subscriber'"'"'s geographic location but is not a callable telephone number, wherein the subscriber is a voice-over-internet-protocol subscriber; and

providing the subscriber'"'"'s geographic location and the subscriber'"'"'s assigned local telephone number to an automatic location information database of a public safety system.

35. The method of claim 34, 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.

36. A non-transitory, computer-readable medium wherein the medium is a computer memory 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, packet switched telephone number to a subscriber, the non-local, packet switched telephone number comprising a callable telephone number;

assigning a local telephone number to a subscriber that is associated with the subscriber'"'"'s geographic location but is not a callable telephone number, wherein the subscriber is a voice-over-internet-protocol subscriber; and

providing the subscriber'"'"'s geographic location and the subscriber'"'"'s assigned local telephone number to an automatic location information database of a public safety system.

37. The computer-readable medium of claim 36, 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.

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

assigning a non-local, packet switched telephone number to a subscriber, the non-local, packet switched telephone number comprising a callable telephone number;

assigning a local telephone number to a subscriber that is associated with the subscriber'"'"'s geographic location but is not a callable telephone number, wherein the subscriber is a voice-over-internet-protocol subscriber;

providing the subscriber'"'"'s geographic location and the subscriber'"'"'s assigned local telephone number to an automatic location information database of a public safety system;

determining, using a packet-switched routing apparatus, whether a called number is a predetermined number including at least an emergency number; and

determining whether a calling number is local to the subscriber, and when the calling number is not local to the subscriber, the packet-switched routing apparatus substitutes the assigned local telephone number of the subscriber for the calling number and routes the substituted assigned local telephone number to the public safety system that services the subscriber'"'"'s geographic area.

39. The method of claim 38, wherein the emergency number comprises “

9-1-1”

.

40. The method of claim 38, comprising determining the public safety system that services the subscriber'"'"'s geographic area based on the substituted assigned local telephone number for the calling number.

41. The method of claim 40, comprising displaying the non-local, packet switched telephone number in an Alternate Number field viewable at a public safety answering point of the public safety system that services the subscriber'"'"'s geographic area.

42. A non-transitory, computer-readable medium wherein the medium is a computer memory 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, packet switched telephone number to a subscriber, the non-local, packet switched telephone number comprising a callable telephone number;

assigning a local telephone number to a subscriber that is associated with the subscriber'"'"'s geographic location but is not a callable telephone number, wherein the subscriber is a voice-over-internet-protocol subscriber;

providing the subscriber'"'"'s geographic location and the subscriber'"'"'s assigned local telephone number to an automatic location information database of a public safety system;

determining, using a packet-switched routing apparatus, whether a called number is a predetermined number including at least an emergency number; and

determining whether a calling number is local to the subscriber, and when the calling number is not local to the subscriber, the packet-switched routing apparatus substitutes the assigned local telephone number of the subscriber for the calling number and routes the substituted assigned local telephone number to the public safety system that services the subscriber'"'"'s geographic area.

43. The computer readable medium of claim 42, wherein the emergency number comprises “

9-1-1”

.

44. The computer readable medium of claim 42, comprising determining the public safety system that services the subscriber'"'"'s geographic area based on the substituted assigned local telephone number for the calling number.

45. The computer readable medium of claim 44, comprising displaying the non-local, packet switched telephone number in an Alternate Number field viewable at a public safety answering point of the public safety system that services the subscriber'"'"'s geographic area.
