With the flexible architecture of Messaging, you can mix different types of storage servers on the same system. Using this flexible design, you can continue using existing email servers in your network environment. This flexibility also ensures that you are not locked into the product of a specific email vendor.
When you use a third-party storage server as the storage destination for user messages , you still need the Avaya storage server for:
The AxC/Directory server role that relays messages between the application server and third-party servers
Notification capabilities
The LDAP database
Store user properties, name, and greeting recordings
Stores voice messages
Note You can turn off the storage functionality, if needed.
