TELEPHONE NUMBER GROUPING SERVICE FOR TELEPHONE SERVICE PROVIDERS

An existing telephone service provider network may be adapted to associate a single telephone number with multiple telephone service user devices. The multiple provisioned telephone numbers may be grouped such that service activity originating from a device associated with one of the grouped telephone numbers appears to originate from a selected (and possibly different) one of the grouped telephone numbers, and such that service activity destined for a device associated with one of the grouped telephone numbers may be forwarded to one or more and/or each of the devices associated with the grouped telephone numbers. Any suitable set of provisioned telephone numbers may be grouped including, but not limited to, a set of two provisioned telephone numbers.
