The Messaging administrator determines the storage destination for the voice messages of each user. Because the storage destination is determined on a per user basis, users can use their current email server for storing voice mail.
In a single storage configuration, when the administrator turns off the message storage function of the Avaya storage server, the AxC/Directory server sends all messages to the third party server.
In a dual storage configuration, the administrator configures the system so that the AxC/Directory server sends some messages to the Avaya storage server and others to the third-party server.
