Your company policy indicates that voice mail messages from internal users can be no longer than 120
seconds. Your company policy also indicates that voice mail messages from outside callers can be no longer
than 300 seconds.
All UCM voice mail message length options are currently set to the defaults.
Which of the following options should you modify in Cisco Unity Connection? (Select the best answer.)

A.
Message Settings > Maximum Message Length

B.
Class of Service > Recorded Name-Maximum Length

C.
Class of Service > Message Length-Maximum Length

D.
Advanced > Conversations > System Broadcast Message: Maximum Recording Length in Milliseconds

Explanation:
You should modify the Class of Service > Message LengthMaximum Length field in Cisco Unity Connection to
configure a 120second voice mail recording limit for internal users. The Class of Service > Message
LengthMaximum Length field sets a maximum length in seconds for users who are assigned to the specific
Class of Service (CoS) that is being modified. Cisco Unity Connection enables an administrator to limit voice
mail recording lengths for internal users separately from outside callers. Therefore, you can configure Unity
Connection so that outside callers can leave longer messages than internal users. By default, both outside
callers and internal users are limited to 300second voice mail messages. Therefore, you only need to configure
the Class of Service > Message LengthMaximum Length field to 120 to meet your company’s requirements.
CoS settings can be modified for multiple users by using the Phone section of a Unity Connection user template
or by using Bulk Edit Mode.
You should not modify the Message Settings > Maximum Message Length field, because this field limits the
length of voice mail messages that are left by outside callers. By default, the Maximum Message Length field is
configured to 300 seconds, which is your company’s requirement; therefore, you need not modify this field.
However, if you were to modify the Maximum Message Length field value for a single user, you would edit the
field on the Message Settings page of the user’s account. There are three typical ways to create users in Unity
Connection: local manual creation, import from Cisco Unified Communications Manager (UCM), or
synchronization by using Lightweight Directory Access Protocol (LDAP).
You can also modify the setting for a number of users at once by editing the Maximum Message Length field in
Bulk Edit Mode. In addition, you can configure the Maximum Message Length field on the Message Settings
page of a voice mail user template to apply a nondefault maximum message length to any new user accounts
that are based on the template.
You should not modify the Class of Service > Recorded NameMaximum Length field. This field applies to users
who have been assigned to the CoS and limits the length of time allotted to a user for recording the voice
mailbox name that will be announced to callers who reach that user’s voice mail. By default, the Recorded
NameMaximum Length field is set to 30 seconds; the field’s configurable range is from one through 100
seconds.
You should not modify the Advanced > Conversations > System Broadcast
Message: Maximum Recording Length in Milliseconds field, because this field limits the length of system
broadcast messages that are played for all voice mail users. System broadcast messages are typically used for
announcements and can be scheduled to start and end on specific dates and times. By default, the maximum
length of a broadcast message is configured to 300,000 milliseconds, which is 300 seconds or five minutes.
