There are two Exchange 2010 Unified Messaging user interfaces available to subscribers: the Telephone User Interface (TUI) and the Voice User Interface (VUI). These two interfaces together are called Outlook Voice Access. Outlook Voice Access can be used when subscribers access the Unified Messaging system from an external or internal telephone to access their individual mailbox, including their personal e-mail, voice messages, contacts, and calendaring information in their Exchange 2010 mailbox.

If you want to prevent users from receiving voice mail but want to allow them access to their Exchange 2010 mailbox using Outlook Voice Access, you can enable users for Unified Messaging and configure the users' mailbox with an extension number that isn't currently being used by another user in the organization.

Important:
For the VUI or Automatic Speech Recognition (ASR) to be used for subscriber access, it must be enabled on the UM dial plan to enable the VUI functionality as described in the earlier scenarios.

The following scenarios demonstrate how Outlook Voice Access can be used for subscriber access from a telephone:

• Access e-mail   An Outlook Voice Access user places a call to the subscriber access number from a telephone and wants to access voice mail. The voice prompt says, "Welcome. You're connected to Microsoft Exchange. To access your mailbox, please enter your extension. To contact someone, press the # key." After the user enters a mailbox extension number, the voice prompt says, "Please enter your PIN and press the # key." After the user enters a PIN, the voice prompt says, "You have 2 new voice mails, 10 new e-mail messages, and your next meeting is at 10:00 A.M. Please say voice mail, e-mail, calendar, personal contacts, directory, or personal options." When the user says "E-mail," Unified Messaging reads the message header and then the name, subject, time, and priority for the messages that are in the subscriber's mailbox.
  
  
• Access calendar   An Outlook Voice Access user places a call to the subscriber access number from a telephone and wants to access voice mail. The voice prompt says, "Welcome. You're connected to Microsoft Exchange. To access your mailbox, please enter your extension. To contact someone, press the # key." After the user enters a mailbox extension, the voice prompt says, "Please enter your PIN and press the # key." After the user enters a PIN, the voice prompt says, "You have 2 new voice mails, 10 new e-mail messages, and your next meeting is at 10:00 A.M. Please say voice mail, e-mail, calendar, personal contacts, directory, or personal options." When the user says "Calendar," Unified Messaging says, "Sure, and which day should I open?" The user says, "Today's calendar." Unified Messaging responds by saying, "Opening today's calendar." Unified Messaging reads each of the calendar appointments for that day for the user.
  
  

  Note:
  If a Unified Messaging server encounters a corrupted calendar item in a user's mailbox, it will fail to read the item, but will return the caller to the Outlook Voice Access main menu and will skip reading any additional meetings that may be scheduled for the rest of the day.

• Access voice mail   An Outlook Voice Access user places a call to the subscriber access number from a telephone and wants to access voice mail. The voice prompt says, "Welcome. You're connected to Microsoft Exchange. To access your mailbox, please enter your extension. To contact someone, press the # key." After the user enters a mailbox extension number, the voice prompt says, "Please enter your PIN and press the # key." After the user enters a PIN, the voice prompt says, "You have 2 new voice mails, 10 new e-mail messages, and your next meeting is at 10:00 A.M. Please say voice mail, e-mail, calendar, personal contacts, directory, or personal options." The user says "Voice mail" and Unified Messaging reads the message header and then the name, subject, time, and priority for the voice messages that are in the user's mailbox.
  
  

  Note:
  If speech recognition is enabled, users can access their UM-enabled mailbox using speech input. However, subscribers can also use touchtone, also known as dual tone multi-frequency (DTMF), by pressing 0. Speech recognition is not enabled for PIN input.

• Locate an e-mail alias   An Outlook Voice Access user places a call to the subscriber access number from a telephone and wants to locate a person in the directory by spelling the e-mail alias. The voice prompt says, "Welcome. You're connected to Microsoft Exchange. To contact someone, press the # key." The user presses the # key, and then spells the name of the person using DTMF or touchtone inputs.
  
  

  Note:
  The directory search feature with subscriber access is not speech-enabled. Users will be able to spell the name of the person who they want to contact only using DTMF inputs.

  Important:

  In some companies (especially in East Asia), office telephones may not have letters on the keys of the telephone. This makes the spell-the-name feature that uses the DTMF interface almost impossible to use, without a working knowledge of the key mappings. By default, Exchange 2010 Unified Messaging uses the E.161 key mapping. For example, 2=ABC, 3=DEF, 4=GHI, 5=JKL, 6=MNO, 7=PQRS, 8=TUV, 9=WXYZ. When inputting a combination of letters and numbers, for example, Mike1092, the numeric digits are mapped to themselves. For an e-mail alias of Mike1092 to be entered correctly, the user must press the numbers 64531092. Also, for characters other than A-Z and 0-9, there won't be a telephone key equivalent. Therefore, these characters shouldn't be entered. For example, the e-mail alias mike.wilson would be entered as 6453945766. Even though there are 11 characters to be input, only 10 digits are entered by the user because the period (.) does not have a digit equivalent.

Important:
If you need to access the e-mail message after you delete it using Outlook Voice Access, you can use Outlook Web App or Outlook to move the e-mail message back into the appropriate folder from the Deleted Items folder. You can't use Outlook Voice Access to access the Deleted Items folder.
