ABSTRACT:
A method and system of the present invention updates a replicated database of a telecommunications network system. A call transport system forwards calls from a local telephone station to a destination. A signaling system is operatively connected to the call transport system and includes primary site databases containing customer records for call routing and other signaling functions and at least one secondary site database containing the customer records of the primary site database. Both primary and secondary site databases maintain multiple versions of the same customer record so that queries of a call can use a version number to access the corresponding version of the record in the same database for consistent routing and other signaling information. A customer record is updated in the primary site database and that information is transmitted through the signaling network to the secondary site database containing the replicated version of the record. The records are then updated according to the sequence of the version number. The processing of all calls querying the previous version of the primary and secondary site database record is completed before the previous version of the database record is deleted.
