Some valuable benefits are offered through integrating fax messages and voice mail with e-mail and calendaring systems, such as ease of use, increased productivity, and lowered costs. These benefits are delivered through Exchange Server 2007 Unified Messaging unifying fax and voice mail traffic with other data items in users' existing inboxes and then making all of these data items available to the user in several different ways. Exchange Server 2007 reduces the cost of providing fax and voice mail services while at the same time providing services (such as voice access to calendar items) that are not available on other systems, by allowing for centralized deployment and management of unified messaging services.
