When the Avaya message store is the storage destination for user messages, the message store resides on the same server that performs the storage role. When a third-party server is the storage destination for user messages, the message store resides on a third-party, corporate storage server.
When you use a third-party storage server, your system still requires at least two Avaya servers: one for the AxC/Directory server, and one or more for application servers.
You can use the AxC/Directory server for notification capabilities, the LDAP database, and to provide communications between the application servers and the third-party storage server. You can also use the AxC/Directory server to store user properties, name, and greeting recordings. All voice messages are stored on the user’s third-party storage server.
