The Unified Messaging role enables users to receive voice messages, faxes, and e-mail in their personal Exchange mailbox. This data can then be accessed from either a telephone or a computer. Unified Messaging integrates Exchange Server 2007 Service Pack 1 (SP1) with the telephony network in an organization and brings Unified Messaging to the core of the Exchange Server feature set.

When you install the Unified Messaging server role on a computer that does not have other Exchange Server 2007 server roles installed, the Exchange Server 2007 SP1 organization must contain other Exchange Server 2007 servers on which the Mailbox, Hub Transport, and Client Access server roles are installed. However, the Unified Messaging server role can also be installed on the same server with other Exchange Server 2007 SP1 server roles.

Note:
In the current version of the Solution, fax services are not supported.

Unified Messaging server is domain member and keeps the configuration information in Active Directory directory service; therefore, the server can be provisioned using security credentials of domain-based service accounts. The list of accepted domains and accepted recipients is synchronized from Active Directory to the Hub server, and from there the EdgeSync process syncs domains and recipients out to the Internet Incoming Hub servers.

The solution architecture includes steps to deploy System Center Operations Manager to monitor your Exchange server deployment.
