Abstract
A method for providing local number portability between subscriber lines served by a distributed switch call manager (DSCM) involves updating translation tables of the DSCM to direct call control messages to a media gateway (MG) that serves the ported number. The service features and service feature profile of the ported subscriber are ported concurrently with the directory number, without re-provisioning.
