UM provides the ability
to unify your various mailboxes including e-mail, voice mail, and fax. Exchange 2007 UM
brings many of the traditional voice mail features to e-mail in the same way OCS brings
Private Branch Exchange (PBX) features to instant messaging (IM).
What Is It?
Exchange 2007 UM allows you to access your voice mail, e-mail, and faxes all from a single
inbox via your Outlook 2007 client or even Outlook Web Access. Exchange 2007 UM also
incorporates a feature known as Outlook Voice Access (OVA), allowing end-users to access
their voice mail, e-mail, and even Outlook calendar via any telephone. OVA uses voice
recoginizition technology to perform commands based on the spoken voice. For example, OVA
allows you to call Exchange and enter your mailbox number and passcode just as you would
typically access voice mail remotely. However, with OVA you can access new voice mail
messages by simply speaking into the phone the words voice mail. OVA will then play any new
voice mails waiting in your inbox. Alternatively, you can simply launch your Outlook client
and listen to voice mails through your computer speakers.
How Does It Work?
UM works by integrating Exchange Server 2007 with your existing PBX phone system.
Connectivity between the PBX and Exchange Server 2007 typically involves a Voice over
IP (VoIP) gateway device linking the two systems. The VoIP gateway accepts unanswered
incoming calls from the PBX and routes them to the appropriate Exchange mailbox to allow
the caller to record a voice-mail message.
