When an authenticated UM-enabled user calls in to the Microsoft Exchange 2007 Unified Messaging system, the call is received by your organization's telephony network and then passed to an Exchange 2007 Unified Messaging server that handles and routes the incoming call. This topic discusses the message flow for incoming Outlook Voice Access calls to an Exchange 2007 Unified Messaging server.

Outlook Voice Access

With Exchange 2007 Unified Messaging, UM-enabled users or subscribers can access their e-mail, contacts, and calendaring information by using a standard analog, digital, or cellular telephone. When a UM-enabled user uses Outlook Voice Access, they can perform the following tasks:

  • Listen to new and saved e-mail and voice mail messages.

  • Forward, reply, save, and delete e-mail and voice mail messages.

  • Interact with their calendar.

  • Locate a person in the global address list (GAL) or personal contacts.

  • Send a voice message to a person

  • Change their PIN, spoken name, or greetings.

  • For more information about subscriber access in Exchange 2007 Unified Messaging, see Understanding Unified Messaging Subscriber Access.

Outlook Voice Access Message Flow

Outlook Voice Access incoming calls and messages that are created by using Outlook Voice Access are routed to an Exchange 2007 Unified Messaging server and then to the Mailbox server. However, if a message is submitted by using Outlook Voice Access, for example, a change in the schedule of a meeting from a subscriber, the message is submitted to a Hub Transport server before it is routed to the appropriate mailbox for the Exchange 2007 recipient or recipients.

Figure 1 illustrates how incoming calls and messages placed by subscribers or UM-enabled users flow in an Exchange 2007 organization.
