Abstract

The present invention relates generally to logical telephone numbers. In particular, dynamic number users are able to obtain dynamic numbers and to map those numbers to routable numbers of their choosing. The present invention provides a tool for protecting privacy while sharing and/or publicizing a number for public purposes. The present invention relates to a Dynamic Telephone Number Service (DTNS.) wherein users are provided with a logical temporary telephone number that is mapped dynamically to a physically addressable number. The use of the DTNS allows a dynamic number user to publish the logical number, thus avoiding the need to publish private information and phone numbers for public purposes. Further, the logical number is not permanently assigned, but rather is temporary and provided to the dynamic number user for a relatively short period of time.

Claims

1. A system for assigning dynamic telephone numbers on a temporary basis and routing calls made to said dynamic telephone numbers, said system comprising:

means for a requestor to request a dynamic telephone number;

means for assigning said dynamic telephone number to said requestor;

means for mapping said dynamic telephone number to a standard telephone number;

means for routing calls made to said dynamic telephone number from said dynamic telephone number to said standard telephone number; and

wherein said dynamic telephone number is made available to said caller via caller ID, and

wherein said dynamic telephone number is substituted for said standard telephone number in the Automatic Number Identification field and the standard telephone number is thus hidden from said caller.

2. A system for assigning dynamic telephone numbers on a temporary basis and routing calls made to said dynamic telephone numbers, said system comprising:

means for a requestor to request a dynamic telephone number;

means for assigning said dynamic telephone number to said requestor;

means for mapping said dynamic telephone number to a standard telephone number;

means for routing calls made to said dynamic telephone number from said dynamic telephone number to said standard telephone number; and

wherein said dynamic telephone number is made available to said caller via caller ID, and

wherein said caller ID displays a Reply To field set to said dynamic telephone number and the standard telephone number is thus hidden from said caller.
