Communications Server 1000 with
Microsoft Exchange Server 2007
Unified Messaging
Overview CS 1000 support for Microsoft Exchange Server 2007 Unified Messaging
enables interoperability between the voice service capabilities of
Communication Server 1000 and the Unified Messaging solution provided
as a component of Microsoft Exchange Server 2007. This interoperability
provides the following capabilities:
•Call Answering: With call answering, Communications Server 1000
with Microsoft Exchange Server 2007 Unified Messaging is configured
to answer incoming calls on behalf of a user by playing their personal
greeting, recording a voice message from the caller, and submitting it
for delivery to the user inbox as an e-mail message.
•Subscriber Access: enables dial-in access for users. A subscriber
dialing into the Microsoft Exchange Unified Messaging system
accesses their mailbox using Outlook 2007 Voice Access, enabling
access using either a telephone keypad or voice inputs. When dialed
into the Unified Messaging system using a telephone, a subscriber or
user can perform the following functions:
—Listen to, forward, or reply to voice mail messages, and call the
sender of the voice mail.
—Listen to calendar information.
—Access or dial contacts stored in the global address list or in a
personal contact list.
—Accept or cancel meeting requests.
—Set a voice mail Out-of-Office message.
—Set security preferences and personal options.
•Auto Attendant: Provides a set of voice prompts that provides access
to the Microsoft Exchange Unified Messaging system by external
users. Using the Auto Attendant, the external user navigates the menu

10 Communications Server 1000 with Microsoft Exchange Server 2007 Unified Messaging
structure, using either the telephone keypad or speech inputs, to place
a call to a user or to locate a user for the purpose of placing a call to
that user. In addition, the Auto Attendant gives system administrators
the ability to perform the following functions:
—Create a customizable set of menus for use by external users.
—Define informational greetings, business hours greetings, and
non-business hours greetings, and greetings for holiday schedules.
—Add instructions for callers describing how to search the
organizational directory, and how to connect to a specific user by
means of their extension number.
—Enable access for external callers to the operator. For more
information, see “Configure the Operator Assistance feature” (page
30).
•Play on Phone: Allows a Microsoft Exchange Unified
Messaging-enabled user to access a voice mail message
through Outlook 2007 or Outlook Web Access and listen to the
message over a telephone.
•Message Waiting Indication (MWI): Designed by Geomant, the MWI
application is an add-on to the Microsoft Exchange Unified Messaging
Server 2007 which provides support for MWI notifications to users
connected to the Microsoft Exchange Unified Messaging Server. For
more information on the installation and configuration of the Geomant
MWI application, see “Install Geomant Message Waiting Indicator
(MWI) application” (page 33) and “Configure Geomant Message
Waiting Indicator (MWI) application” (page 34).
Note: The MWI 2007 software is a third-party software developed
by Geomant. Information on Geomant and MWI 2007 is provided
in this documentation for ease of reference only. Nortel does not
sell, warrant or provide operational support for Geomant’s MWI
2007 software product, nor warrant the accuracy of MWI 2007
descriptions contained in this document. Customers using this
document are strongly recommended to obtain the most recent MWI
2007 documentation from Geomant.

Overview 11
Multiple Microsoft Exchange Unified Messaging servers on a single
network
Multiple Servers can be configured for a single network to ensure the
effective handling of potential issues caused by challenges of:
•Capacity: Each Microsoft Exchange Unified Messaging Server is
capable of supporting a maximum of 200 total concurrent (combination
of inbound and outbound) calls. In larger customer networks that need
to support a higher volume of concurrent calls, additional Microsoft
Exchange Unified Messaging Servers can be configured in the same
network so that users can be load-balanced.
•Redundancy: An additional Microsoft Exchange Unified Messaging
Server can be configured as a redundant server in a network by
utilizing the Least Cost Routing Mechanism on the Network Routing
Service (NRS) - configuring an additional Microsoft Exchange Unified
Messaging Server provides a greater measure of fault tolerance for
the services provided, allowing a continuation of those services in the
event of system failure
•Geographical location: If network systems are located across multiple
geographic locations, Microsoft Exchange Unified Messaging Servers
can be implemented in such a way that they are both local and specific
to each location. Configuring multiple servers in this way would

12 Communications Server 1000 with Microsoft Exchange Server 2007 Unified Messaging
automatically result in load sharing of access to Microsoft Exchange
Unified Messaging services by users in the network.
Operational Considerations
Considerations specific to Microsoft Exchange Server 2007 are as follows:
•The only supported codecs are G711 and G723.
•RFC2833 is required for DTMF digit transmission to the Exchange
Server.
•Exchange Server 2007 must always be configured as a static endpoint
on the NRS as Registration is not supported.
•The Fax on UM capability is supported.
•Geomant Message Waiting Indicator (MWI) 2007 is a required add-on
for MWI functionality.
•Microsoft Outlook 2007 is required.
•Exchange Server 2007 requires the use of x64 processors.
•For the Play on Phone option to function, the default Outlook data file
used must be of type .ost. If the default Outlook data file is of type
.pst, the Play on Phone option will not be available.
•Calling a non-Exchange user using the Auto Attendant functionality is
not supported by Microsoft Exchange Unified Messaging.
•Due to known issue concerning support of Payload 101 for RFC2833,
intermittent DTMF issues will be experienced with PC-based clients.
•Interoperability with BCM/SRG and CS 2100 over H.323 causes
speech path issues due to non-handling of RE-INVITE requests by
Microsoft Exchange Unified Messaging Server.
Considerations specific to the Geomant MWI Application are as follows:
•In a Main Office-Branch Office (MO-BO) environment, MWI
functionality is provided in either Normal or Local mode, as MWI is not
supported as multiple instances in the same domain.
•In a Geographic Redundant System environment, MWI functionality
is provided in either a Primary Call Server (PCS) or a Secondary Call
Server (SCS) system, as MWI is not supported as multiple instances
in the same domain
Considerations specific to the Communication Server 1000 are as follows:
•Only CDP dialing is supported between the home CS 1000 and the
UM Server - users dial in to the home CS 1000 using any configured

Overview 13
dialing plan to access services provided by Communications Server
1000 with Microsoft Exchange Server 2007 Unified Messaging.
•Configuration of the voice mail soft key cannot be changed if there is
a combination of CallPilot and Microsoft Exchange Unified Messaging
voice mail users on a single node. A recommended deployment
solution would be to have CallPilot users and Microsoft Exchange
Unified Messaging users associated with separate Line TPS nodes.
The voice mail soft key feature on the phone set assigns a unique key
to each of the voice messaging functions.
•While operating with an MCS PC Client, Microsoft Exchange Unified
Messaging calls can not be placed on hold.
•The existing limitation on the NRS of multiple endpoints with the same
static IP address is not supported. This affects network environments
where two CDP domains are configured to use the same Microsoft
Exchange Server 2007.
•The IP Softphone 2050 does not support RFC2833; therefore, it can
not be used with the Subscriber Access and Auto Attendant features of
the Exchange Server 2007.
•If a call originates from an H.323 endpoint (CS 1000/BCM/SRG) and
is tandem transferred by the CS 1000 to the Microsoft Exchange
Unified Messaging Server using SIP, the Subscriber Access and Auto
Attendant feature can only be accessed by voice command and not by
keypad (DTMF), as there is no support for RFC2833 over an H.323
network.
•If the far end does not support RFC2833 (with a payload value of 101),
the Play on Phone functionality is not supported.
•Calls forwarded by Integrated Call Director (ICD) to Microsoft
Exchange Unified Messaging are not supported.
Microsoft Exchange Unified Messaging operational characteristics
•When a Microsoft Exchange Unified Messaging-enabled user plays
back stored voice mail messages, the order of playback begins
with the last message recorded. That is, when voice mail has been
received (in order) from User 1, User 2, and User 3, the messages are
replayed in the order of User 3, User 2, User 1.
•For a voice mail message that is a reply to an earlier voice mail
message, the reply message is played before the playback of the
original message.
•If there is only one voice mail message waiting for the user, it is not
possible to undelete that voice mail message once it has been deleted.

14 Communications Server 1000 with Microsoft Exchange Server 2007 Unified Messaging
•Voice mail messages that have been listened to will continue to
register as a new message until the next option is used.
•When a user dials the Auto Attendant number (with speech enabled)
and does not provide a name, Auto Attendant repeats the prompt for
a name three times. After the third prompt, the call is forwarded to the
operator automatically.
CS 1000 set configuration
This section details appropriate set configuration to provide operation
for Communications Server 1000 with Microsoft Exchange Server 2007
Unified Messaging.
Required class of service configurations are as follows:
•CFXA (Call Forward External): Allowed
•FNA (Call Forward No Answer): Allowed
•HTA (Hunting): Allowed
•CLS (Trunk: Call Access Restriction): Unresricted
•MWA (Message Waiting Indicator): Allowed
Both FDN (Call Forward No Answer DN) and Hunt (Hunt DN) must be
set to the value for the configured Subscriber Access DN.
SIP provisioning guidelines
This section details the SIP provisioning requirements for operations
on Communications Server 1000 with Microsoft Exchange Server 2007
Unified Messaging.
Assumptions
•Call model and traffic rate calculations are based on the assumptions
provided by Microsoft for a typical heavy user, as described at the
following URL: http://msexchangeteam.com/archive/2006/08/14/42
8677.aspx
•A single Microsoft Unified Messaging server can have up to 3000
heavy users associated with it.
•All Microsoft Unified Messaging messages are received by telephone
using an SIP Trunk, and not using Microsoft Exchange Client (which
does not use an SIP Trunk).
•The use of Auto Attendant for Thru-Dial and other custom voice menu
services makes the following assumptions:

Overview 15
—Menu selection and call transfer time is 30 seconds, with a
completed call duration of 180 seconds.
—Busy Hour (BH) Auto Attendant usage is 0.35 calls per hour for
each Microsoft Unified Messaging user.
•Auto Attendant operation requires the usage of two SIP trunks, which
remain in use for the duration of the call.
•If Microsoft Unified Messaging system usage differs from the call model
described for the purpose of SIP trunk table calculations, it is the
responsibility of the customer to monitor the actual usage of the system
and ensure that there are sufficient SIP trunks available for use.
