There are multiple methods that you can use to install the Unified Messaging (UM) server role on a computer that is running Exchange Server 2007. The Unified Messaging server role can be installed on a single computer that has no other Exchange Server 2007 server roles installed, or on a computer that is running another Exchange Server 2007 server role. This topic discusses the methods that you can use to install the Unified Messaging server role.

Important:
After you install the Unified Messaging server role, you must perform other tasks before the UM server can process incoming calls. To complete the steps that are required to enable and configure UM, see Post-Installation Tasks.
