Types of Telephone Systems
Phone System
Description
Centrex
• Organization leases several lines from
the phone company
Key Telephone System
Private Branch
Exchange (PBX)
• All calls are switched at the phone
company central office
• Each phone line connects to multiple
telephones in the organization
• All the phones associated with the line
ring
• PBX switches telephone calls on the
customer premises
• Each user has a unique extension
Components of a Telephony System
Components of a telephony system include:
• Direct Inward Dialing (DID)
• Dial plan
• Hunt group
• Pilot number
• Coverage path
• Call transfer
Types of PBXs
PBX Type
Description
Analog
• Sends voice and signaling information as actual
analog sounds
• Encodes analog sound into a digital format
Digital
IP PBX
Hybrid PBX
• Uses packet switching to carry voice
conversations over data networks
• Acts as a gateway between telephone and data
networks
• Provides both digital and IP PBX capabilities
What Is a VoIP Gateway?
VoIP gateway converts traditional circuit-switching
protocols into packet-switched protocols
• Circuit-switched networks use a dedicated connection
between two network devices, such as phones
• Packet-switched networks divide each data message into
packets that are sent to their destination and
reassembled
• VoIP enables IP-based networks as the transmission
medium for telephone calls
Unified Messaging Protocols
Protocol
Description
Session Initiation
Protocol (SIP)
• Signaling protocol used to create,
manipulate, and disconnect interactive
communication sessions on an IP
network
• Protocol used to transmit streaming
voice or video data over an IP network
• IP-based network communication
between a client, the Unified Messaging
server, the Client Access server, and
computers running other Exchange
Server 2010 server roles
Real-Time Transport
Protocol (RTP)
Unified Messaging
Web Services
Lesson 2: Introducing Unified Messaging
• What Is Unified Messaging?
• Overview of Unified Messaging Communications
• Server Communications for Unified Messaging
• Call-Answering Features of Unified Messaging
• Outlook Voice Access Features
• How Unified Messaging Works with a VoIP Gateway
• Integrating Unified Messaging with OCS 2007 R2
• International Requirements for Unified Messaging
What Is Unified Messaging?
Unified Messaging combines voice messaging and
e-mail messaging into one store that is accessible from
a telephone and a computer
Unified Messaging features include:
• Call answering
• Outlook Voice Access
• Play on Phone
• Voice mail preview
• Protected voice mail
• Call answering rules

Server Communications for Unified Messaging
Unified Messaging servers communicate with:
• Active Directory domain controllers to locate
user mailboxes and subscriber information
• The Mailbox server role to access subscribers’
personal greetings and the contents of their
mailboxes
• The Hub Transport server role to send messages
with voice mail or fax attachments
• The Client Access server role when messaging
clients need to communicate with the Unified
Messaging server using SIP
Call-Answering Features of Unified Messaging
The Unified Messaging server can accept the following
types of calls:
• Voice messages are captured as MIME messages
and routed to the Mailbox server using SMTP
• Outlook Voice Access calls provide prompts for
Unified Messaging users to access their
mailboxes
• Auto attendant calls provide prompts for users to
locate and call Unified Messaging users
Outlook Voice Access Features
With Outlook Voice Access, users can:
• Listen to new and saved e-mail and voice-mail messages
• Forward, reply, save, and delete e-mail and voice
messages
• Review, accept, or decline meetings
• Locate users in the global address list and send
messages
• Change their PINs, spoken names, or greetings

Integrating Unified Messaging with OCS 2007 R2
You can integrate Unified Messaging with OCS 2007
R2 to provide access to messaging and voice
functionality using both messaging and OCS clients
OCS 2007 R2 provides:
• Instant messaging
• Presence information
• Web conferencing
• Audio conferencing
• VoIP telephony
• Response Group service
International Requirements for Unified Messaging
Unified Messaging provides language packs to satisfy
international requirements for Unified Messaging
A language pack adds the following:
• Copies the language prompts that will be used to

• What Is a Unified Messaging Dial Plan?
• What Is a Unified Messaging IP Gateway?
• What Is a Unified Messaging Hunt Group?
• What Is a Unified Messaging Mailbox Policy?
• What Is a Unified Messaging Auto Attendant?
• Rules for Call Answering
Process for Installing Unified Messaging
1 Install the Unified Messaging server role
2 Create a Unified Messaging dial plan
3 Create a Unified Messaging IP gateway
4 Create a Unified Messaging hunt group
5 Configure a Unified Messaging mailbox policy
6
Enable mailboxes for Unified Messaging
7
Create an auto attendant
What Is a Unified Messaging Dial Plan?
Unified Messaging dial plans:
• Are used to link user mailboxes to their
extension numbers
• Are used to configure default settings such as
greetings, dial codes, and languages
• Are managed using the Exchange Management
Shell or the Exchange Management Console
You need at least one Unified Messaging dial plan, and that
dial plan requires a Unified Messaging server and an
associated Unified Messaging IP gateway
What Is a Unified Messaging IP Gateway?
A Unified Messaging IP gateway is an Active Directory
container object that logically represents a physical
VoIP gateway or IP-PBX device
Unified Messaging IP gateways:
• Are managed using the Exchange Management
Shell or the Exchange Management Console
• Can be disabled to drop all calls or stop receiving
new calls
What Is a Unified Messaging Hunt Group?
Unified Messaging hunt groups:
• Are logical representations of an existing PBX
hunt group to link IP gateways and dial plans
• Are used to locate the PBX hunt group
• Are managed using the Exchange Management
Shell or the Exchange Management Console
What Is a Unified Messaging Mailbox Policy?
Unified Messaging mailbox policies apply configuration
settings for Unified Messaging–enabled users
You can specify:
• Dial plan
• Maximum greeting length
• Login attempts before the password is reset
• PIN restrictions
• Restrictions on international calling
• Protected voice-mail settings
What Is a Unified Messaging Auto Attendant?
Auto attendants let callers navigate through a voicemenu system to locate, and place calls to, users in
the organization
Auto attendants provide:
• Corporate or informational greetings
• Custom corporate menus
• A directory search function
• The ability to connect to the telephone of
organizational members
Rules for Call Answering
Call answering rules provide users with more control over
their personal call answering system with features such as
special greetings by contact or time of day
Call answering rules include:
• Conditions: If it evaluates to true, then run
• A greeting and menu: Collect caller’s menu
selection
• Actions: Transfer, “Find me,” or leave message
Configure call answering rules in Outlook Web App or
Outlook 2010

Lab Scenario
You are a messaging administrator for A. Datum Corporation.
Your organization has deployed Exchange Server 2010. Your
users expect to have voice access to their mailboxes, so you
must enable this feature and configure Unified Messaging.
Additionally, many native German speakers work at A. Datum,
so you need to install the German language pack so that they
also can use Unified Messaging.
