Communications Server Enterprise Voice leverages the Exchange UM infrastructure to provide call answering, call notification, voice access (including voice mail), auto attendant services, and fax services.

Call Answering

Call answering is the taking of voice messages on behalf of users whose extensions are not answered or are busy. It includes playing a personal greeting, recording a message, and submitting the message to the Exchange Hub Transport Server to be queued up for delivery to the user's mailbox, which is stored on the Exchange mailbox server.

If a caller leaves a message, the message shows up in the user's inbox. If a caller chooses not to leave a message, a missed call notification is stored in the user's mailbox. Users can then access their inboxes using the Microsoft Office Outlook messaging and collaboration client, Outlook Web Access, the Exchange ActiveSync technology, or Outlook Voice Access. The subject and priority of calls can be displayed in a way similar to that of e-mail.

Outlook Voice Access

Outlook Voice Access enables an Enterprise Voice user to access not just voice mail, but also the Exchange inbox, including e-mail, voice messages, calendar, and contacts from a telephony interface. The subscriber access number is assigned by an Exchange UM administrator.

Auto Attendant

Auto attendant is an Exchange UM feature that can be used to configure a phone number that outside users can dial to reach company representatives. In particular, it provides a series of voice prompts that assist an external caller in navigating a menu system. The list of available options is configured on the Exchange UM server by the administrator.

Fax Services

Exchange UM includes fax features, which enable users to receive incoming faxes in their Exchange mailboxes. For details, see "Unified Messaging" in the Microsoft Exchange Server documentation at http://go.microsoft.com/fwlink/?LinkId=135652.

Fax services are not available in Exchange Server 2010.
