With the Avaya Aura® Messaging flexible storage capability, you can use the Avaya message store or a third party storage destination. Messaging supports the following third-party storage destinations:
Microsoft Exchange
VMware Zimbra
All voice messages are stored on the user e-mail account for Exchange or Zimbra message store. Avaya message store is used to store users properties, name, and greeting recordings. Messaging supports 15,000 users with Microsoft Exchange as a storage destination.
You can retrieve only 1000 messages at any point of time from the Zimbra mailbox. The count of 1000 refers to the maximum limit for each of the Unread, Read, and Saved categories of messages. If you have 10,000 messages, that is, about 1 GB of data in your Zimbra mailbox, you must access the mailbox nine more times to retrieve all messages.
Messaging supports the G.711 and GSM 6.10 encoding formats. To determine how much space you need to allocate for message storage, use the formulas to calculate KB of disk space per minute of recorded message provided by the encoding format you choose.
