DRAG DROP
You have a server that has Exchange Server 2013 installed. You plan to configure Unified
Messaging (UM) to connect to an IP-PBX. A telecommunications administrator configures
the following numbers on the IP-PBX:
• First extension number: 12100
• Last extension number: 12499
• Help extension number: 12500
• Incoming pilot number: 12000
You need to configure UM to support the following requirements:
• Users must be able to use Outlook Voice Access.
• Users must be able to receive voice mail when callers connect to the users’
extension.
• Callers must be able to dial into an automated help system hosted by your company,
which uses standard menus and speech-enabled menus.
Which numbers should you use for the UM configurations?
To answer, drag the appropriate number to the correct UM object in the answer area. Each
number may be used once, more than once, or not at all. Additionally, you may need to drag
the split bar between panes or scroll to view content.

Explanation:
Box 1: 12000
Box 2: 12500
Box 3: 12000
Note:
* An Outlook Voice Access number lets a user who is enabled for Unified Messaging (UM)
and voice mail access their mailbox using Outlook Voice Access. When you configure an
Outlook Voice Access or subscriber access number on a dial plan, UM-enabled users can
call in to the number, sign in to their mailbox, and access their email, voice mail, calendar,
and personal contact information.
By default, when you create a UM dial plan, an Outlook Voice Access number isn’t
configured. To configure an Outlook Voice Access number, you first need to create the dial
plan, and then configure an Outlook Voice Access number under the dial plan’s Outlook
Voice Access option. Although an Outlook Voice Access number isn’t required, you need to
configure at least one Outlook Voice Access number to enable a UM-enabled user to use
Outlook Voice Access to access to their Exchange 2013 mailbox. You can configure multiple
Outlook Voice Access numbers for a single dial plan.
* After you create a Unified Messaging (UM) auto attendant, incoming calls to an external
telephone number that a human operator would ordinarily answer are answered by the auto
attendant. Unlike with other Unified Messaging components, such as UM dial plans and UM
IP gateways, you aren’t required to create UM auto attendants. However, auto attendants
help internal and external callers locate users or departments that exist in an organization
and transfer calls to them.* Hunt group is a term used to describe a group of Private Branch eXchange (PBX) or IP
PBX extension numbers that are shared by users. Hunt groups are used to efficiently
distribute calls into or out of a specific business unit. Creating and defining a hunt group
minimizes the chance that a caller who places an incoming call will receive a busy signal
when the call is received.
In a telephony network, a PBX or an IP PBX can be configured to have a single hunt group
or multiple hunt groups. Each hunt group created on a PBX or IP PBX must have an
associated pilot number. Using a pilot number helps to eliminate busy signals and to route
incoming calls to the extension numbers that are available. The PBX or IP PBX uses the
pilot number to locate the hunt group and in turn to locate the telephone extension number
on which the incoming call was received and the extensions that are assigned to the hunt
group. Without a defined pilot number, the PBX or IP PBX can’t locate where the incoming
call was received.
