ABSTRACT:
A method and apparatus for providing a single shadow number to be associated with one or more out of area phone numbers that have registered service addresses in the same local area. For instance, if multiple subscribers with service addresses within the same local calling area choose to use out of area phone numbers, these multiple out of area phone numbers will all be associated with a single shadow phone number that is local within the local calling area. In one embodiment, when a subscriber using an out of area phone number places an E911 call, the out of area phone number as well as the associated shadow number will be sent to the E911 PSAP.
