Abstract

A method for automatically updating a central LNP database shared among a plurality of central office switches is instigated when a message from a provisioning system to add a directory number is received by a central office switch. In response to the message, a first central office switch accesses the central LNP database by sending a query message which contains the directory number to be added and routing data specific to the central office switch. Responsive to the query message, the LNP
database searches for the directory number received from the first central office switch. If the directory number is found, the database queries a second central office switch to determine if the directory number is in use. If the number is in use, the central LNP database returns a failure message to the first central office switch. If the directory number is not found in the central LNP database or if the directory number is not being used by the second central office switch, the directory number and routing data received from the first central office switch and a transaction entry are added to a table corresponding to the first central office switch in the database.
