Abstract

A method of providing number portability for the treatment of calls from a calling party to a specific number of a ported called party is disclosed.
Once the dialed digits are received at a switching office serving the calling party, a determination is made of whether the call is a number that has been ported. If the number has been ported, the new routing information is obtained from an enhanced directory number table resident at the originating office. In the event that the originating office is unable to offer LRN service, information is obtained at an alternate office. Routing information is updated automatically and directly from a network Service Management System (SMS) to each telephone exchange.
