If you want to integrate Exchange Unified Messaging with Office Communications Server, you must perform the following tasks:
- Deploy the following Exchange Server 2007 with SP1 server roles
in either the same or a different forest as Office Communications
Server 2007 R2: Unified Messaging, Hub Transport, Client Access,
and Mailbox. For details about the supported topologies, see
Enterprise Voice
Server-Side Components. For details about deploying Exchange
Server 2007, see the Exchange Server 2007 product documentation at
http://go.microsoft.com/fwlink/?LinkID=139372 . - On the Exchange Unified Messaging server:
- Create a SIP dial plan based on your specific deployment
requirements (for details, see your Exchange documentation). A
location profile should be created on Office Communications Server
that matches the FQDN of the SIP dial plan.
- Associate users with the appropriate SIP dial plan.
- Create a SIP dial plan based on your specific deployment
requirements (for details, see your Exchange documentation). A
location profile should be created on Office Communications Server
that matches the FQDN of the SIP dial plan.
- Also on the Exchange Unified Messaging server, open the
Exchange Management Shell and run the exchucutil.ps1 script, which:
- Creates a Unified Messaging IP gateway object in Active
Directory Domain Services (AD DS) for each Office
Communications Server Enterprise pool or Standard Edition server
that hosts users who are enabled for Enterprise Voice.
- Creates an Exchange UM hunt group for each gateway. The hunt
group pilot identifier will be the name of the dial plan that is
associated with the corresponding gateway.
- Grants Office Communications Server permission to read Exchange
UM Active Directory objects, specifically, the SIP dial plans
created in the previous task.
- Creates a Unified Messaging IP gateway object in Active
Directory Domain Services (AD DS) for each Office
Communications Server Enterprise pool or Standard Edition server
that hosts users who are enabled for Enterprise Voice.
- On the Office Communications Server, run Exchange UM
Integration Utility, which:
- Creates contact objects for subscriber access and auto
attendant.
- Validates that there is a location profile name whose name
matches the Exchange UM
dialplan.FQDN
.
- Creates contact objects for subscriber access and auto
attendant.

| For details about the supported domain topologies for Office Communications Server and integrated Exchange Unified Messaging, see Environmental Requirementsin the Supported Topologies and Infrastructure Requirements documentation. |
Additionally, you must complete the following tasks:
- Work with Exchange administrators, if necessary, to verify the
tasks that each of you will perform to assure a smooth, successful
integration.
- Deploy the Exchange Mailbox, HubTransport, ClientAccess, and
UnifiedMessaging roles in each forest where Exchange Unified
Messaging is deployed. For details about installing Exchange server
roles, see your Exchange 2007 documentation.
- Obtain a certificate for each Exchange Unified Messaging server
from a trusted root CA. The certificates are required for mutual
TLS (MTLS) between the servers running Exchange Unified Messaging
and Office Communications Server. For details about configuring
certificates on servers running Exchange Unified Messaging, see
Important:When Exchange 2007 SP1 Unified Messsaging is installed, it is configured to use a self-signed certificate (to view the certificate, type Get-ExchangeCertificate | fl runfrom the Exchange Management Console on the Exchange 2007 SP1 Unified Messaging server).
Do not delete the self-signed certificate. Without it, Exchange 2007 Unified Messaging cannot communicate with other Exchange 2007 server roles including the Hub Transport Server, which sends voice mail notifications.
The self-signed certificate, however, does notenable Office Communications Server and Exchange 2007 Unified Messaging to trust each other, which is why it is necessary to request a separate certificate from a CA that both trust. - If Office Communications Server and Exchange Unified Messaging
are installed in different forests, configure each Exchange forest
to trust the Office Communications Server forest.
- If necessary, install the Exchange Management Console on each
Unified Messaging server.
- Deploy a Microsoft Office Communications Server 2007 R2
Standard Edition server (minimum requirement) or Enterprise pool.
For details about installation information, see
- Obtain valid phone numbers for Outlook Voice Access and auto
attendant.
- Coordinate names for Exchange UM dial plans and Enterprise
Voice location profiles.
- For each Exchange UM dial plan, select the SIP gateway.
