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.
