Types of Telephone Systems
Phone System
Description
Centrex
• Organization leases several lines from
the phone company
Key Telephone
System
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:
• 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
Lesson 2: Introducing Unified Messaging
• What Is Unified Messaging?
• Unified Messaging Protocols
• 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
• Exchange Server 2010 SP1 Changes Supporting Unified
Messaging
• Integrating Unified Messaging with Lync Server 2010
• International Requirements for Unified Messaging
What Is Unified Messaging?
Unified Messaging combines voice messaging and
email 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
• Voicemail preview
• Protected voicemail
• Call answering rules
(Personal Auto Attendant)
Unified Messaging Protocols
Protocol
Description
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

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 voicemail 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 email and voicemail messages
• Forward, reply, save, and delete email 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

Exchange Server 2010 SP1 Changes Supporting
Unified Messaging
Exchange Control Panel improvements
• Manage Unified Messaging objects in crosspremises deployment
• Unified Messaging reports
UM dial plan improvements
• UM Dial Plan Wizard and Set-UMServer addition
• Secondary UM dial plan addition
Deployment and migration improvements
• Lync Server 2010 deployment support
• Lync Server 2010 migration support
Communication improvements
• New UM Language Pack additions
• Call Answering Rules improvements
• Unified Communications Managed API addition
• Caller Name Display enhancements
Integrating Unified Messaging with Lync Server 2010
You can integrate Unified Messaging with Lync Server
2010 to provide access to messaging and voice
functionality using both messaging and Lync clients
Integrating Exchange 2010 with Lync 2010 provides:
• A single inbox for communications
• Instant messaging and presence information
• Web and audio video conferencing
• VoIP telephony
• Outlook Web App integration
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 used to configure
Unified Messaging dial plans and auto attendants
• Allows the TTS engine to read messages when Outlook
Voice Access users access their inboxes
• Enables ASR for speech-enabled Unified Messaging
dial plans and auto attendants
With Exchange Server 2010 SP1, more than 25 language
packs are available
Lesson 3: Configuring Unified Messaging
• Process for Installing Unified Messaging
• 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

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, Exchange Management Console, or the
Exchange Control Panel
You need at least one Unified Messaging dial plan, which
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, Exchange Management Console, or
Exchange Control Panel
• 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, Exchange Management Console or the
ECP
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 voicemail 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.
Lab Review
