You want to enable a user to access Cisco Unity Connection voice mail by using IMAP.
Which of the following should you modify?

A.
the user’s account configuration

B.
the user’s CoS configuration

C.
the Exchange message store configuration

D.
the user’s interview handler configuration

Explanation:
You should modify the user’s Class of Service (CoS) configuration by setting the Allow Users to Access
Voicemail Using an IMAP Client and/or Single Inbox option on the CoS screen of the Cisco Unity Connection
browser-based graphical user interface (GUI) to enable a user to access voice mail by using Internet Message
Access Protocol (IMAP). Cisco Unity Connection uses CoS to provide some features, such as access to voice
mail by using IMAP and access to deleted voice mail messages. You can implement multiple CoS
configurations in a single Unity Connection environment. In addition, you can modify the IMAP settings for an
individual CoS configuration or use Bulk Edit Mode to edit multiple CoS configurations. Until user templates and
CoS have been configured, user accounts cannot be added to Unity Connection by using the Bulk
Administration Tool (BAT).
To enable IMAP client access to voice mail, you should first edit an existing CoS configuration or create a new
CoS. On the Edit Class of Service page of the CoS configuration, you should select Allow Users to Access
Voicemail Using an IMAP Client and/or Single Inbox. After you have enabled IMAP access, you can configurewhether a user is allowed to download entire voice mail messages by using IMAP. In addition, you can choose
to limit voice mail message downloads to only public messages or to only message headers.
You would not modify the user’s account configuration to enable a user to access voice mail by using IMAP.
Unity Connection user account settings control features that can be configured specifically for individual users,
such as passwords, personal identification numbers (PINs), and touchtone menu settings. For example, you
could configure the Touchtone Conversation Menu Style field to Brief in a user account’s Phone Menu window
to enable that user to hear a shortened version of the Unity Connection touchtone menu instructions when the
user dials into the voice mail system. In addition, you can build user templates or use Bulk Edit Mode to
configure user account settings. For example, CoS settings can also be configured by using the Phone section
of a Unity Connection user template.
You would not modify the user’s Exchange message store configuration to enable a user to access voice mail
by using IMAP. Although Microsoft Exchange Server can be integrated into a Cisco Voice over IP (VoIP)
environment so that voice mails are downloaded to Microsoft Exchange clients, you should configure IMAP
access to voice mail in Unity Connection, not in Microsoft Exchange Server.
You would not modify the user’s interview handler configuration to enable a user to access voice mail by using
IMAP. Interview handlers are responsible for recording a caller’s answers to a series of recorded questions. For
example, you could use an interview handler to conduct a technical support customer satisfaction survey. To
edit an interview handler configuration, you should click Call Management > Interview Handlers in the Unity
Connection GUI. In addition, you can use Bulk Edit Mode to edit existing interview handlers.
