Starting with Exchange 2010 SP1, the Unified Messaging server role relied on Unified Communications Managed API v. 2.0 (UCMA) for its underlying SIP signaling and speech processing. The UCMA platform, along with its prerequisites, must be installed on the UM server before you install or upgrade UM to Exchange 2010 SP2. If any of the prerequisites are missing from the server, Exchange 2010 SP2 Setup will inform you that the component is missing and provide you with a download link so you can download and install it. Then you can continue by restarting Setup for SP2.

The Unified Messaging server role in Exchange 2010 SP2 relies on the following components and requires that they be installed prior to installing SP2:

• Windows Server 2008 or Windows Server 2008 R2 - Installing Windows Server 2008 R2
  
  
• Microsoft .NET Framework 3.5 Service Pack 1 (SP1) - Microsoft .NET Framework 3.5 Service Pack 1
  
  
• Microsoft .NET Framework 3.5 Family Update for Windows Vista x64, and Windows Server 2008 x64 updates - Microsoft .NET Framework 3.5 Family Update for Windows Vista x64, and Windows Server 2008 x64
  
  
• Windows Remote Management (WinRM) 2.0 and Windows PowerShell V2 (Windows6.0-KB968930.msu) - Windows Management Framework Core package (Windows PowerShell 2.0 and WinRM 2.0)
  
  
• Microsoft Speech Platform - Server Runtime (Version 10.1) (SpeechPlatformRuntime.msi)
  
  
• Unified Communications Managed API 2.0, Core Runtime (64-bit) (UcmaRuntimeWebDownloadX64.msi)
  
  

  Note:
  If you've already installed a version of the Unified Communications Managed API v. 2.0 on a Client Access server in your Exchange organization, you must also install a hotfix. For information about how to install the required hotfix, see OCS 2007 R2 Web Service Provider Hotfix KB 981256.

For more information about UCMA, see UCMA 2.0 Core Architecture or Overview of Unified Messaging.

You can download and install Exchange 2010 SP2 on each server or install SP2 from the Exchange 2010 SP2 DVD. Either way, you use the Microsoft Exchange Server 2010 Service Pack 2 Setup wizard to install Exchange 2010 SP2.

• To download and install Exchange 2010 SP2 from the Web, see Exchange Server 2010 SP2.
  
  
• To install Exchange 2010 from the Exchange 2010 SP2 DVD, see Upgrade Exchange 2010 to Exchange 2010 SP1, SP2 or Exchange 2010 SP3.
  
  

Exchange Unified Messaging language packs are version-specific and platform-specific. Since Exchange 2007, there have been separate releases for UM language packs, including the RTM version of Exchange 2007, Exchange 2007 SP1, SP2, and SP3, the RTM version of Exchange 2010, and Exchange 2010 SP1 and SP2. For some of these versions, both 32-bit and 64-bit downloads are available, but for other releases only 64-bit downloads are available.

It's very important that you install the correct version and platform of the UM language packs on a UM server. Don't install UM language packs on a Unified Messaging server that's running an earlier version of Exchange or that's designed for a 32-bit platform.

The last task to perform when you upgrade is to download and install the required Unified Messaging SP2 language packs that you need on the UM servers in your organization. Make sure to install each UM language pack on each UM server and to set the default language on all dial plans that the UM server is associated with. Setting the default language makes that language available to users. Each UM language pack is bundled in a single .exe file. To download the SP2 UM language packs, see Exchange Server 2010 SP2 UM Language Packs.

Important:

To ensure that all Unified Messaging features are available in the UM language packs you install, you must install the Exchange 2010 Client and Server Language Pack on each UM server in the dial plan. If you don’t install the Client and Server Language Pack, some features may not work as expected. Some features, like Voice Mail Preview, will work in the language that's configured on the dial plan, but when only the UM language pack is installed. However, features like Outlook Voice Access and user interface text won’t work in the language chosen by the user without having both the UM language pack and the Client and Server Language Pack installed. The language pack bundle for Exchange Server 2010 Service Pack 2 (SP2) is integrated into the download for Exchange 2010 SP2. To download SP2 for Exchange 2010, see Microsoft Exchange Server 2010 Service Pack 2 (SP2). However, the language pack bundle for Exchange 2010 SP1 is still available. To download and install the additional Exchange 2010 SP1 client and server language packs on servers in your organization, see the Microsoft Exchange Server 2010 SP1 Language Pack Bundle.

After you install the Unified Messaging server, it's in an enabled state. However, before the UM server can answer and process incoming calls, you must add the UM server to a UM dial plan. You can add an Exchange 2010 SP2 UM server to one or more UM dial plans that have different security settings at the same time. For more information, see Add a UM Server to a Dial Plan.

Verify that you've deployed or upgraded the Client Access, Mailbox, and Hub Transport servers in your organization to Exchange 2010. For details, see Verify an Exchange 2010 Installation.

While you're upgrading the UM server running Exchange 2007 SP3, you don't want it to be able to answering incoming calls. Perform one of the following two tasks to prevent the UM server from answering incoming calls:

• Disable Unified Messaging   For information about how to do this, see How to Disable Unified Messaging on Exchange 2007.
  
  
• Remove the UM server from a dial plan   For information about how to do this, see How to Remove a Unified Messaging Server from a Dial Plan.
  
  

Unified Messaging language packs make it possible for Exchange 2007 and Exchange 2010 UM servers to speak additional languages to callers and recognize languages other than US English (en-US) when callers use Automatic Speech Recognition (ASR) or when voice messages are transcribed. Several UM language packs are available for Exchange 2010 SP2.

After you install the Unified Messaging sever role, only the en-US UM language pack is available. If you've installed other UM language packs in addition to the en-US language pack on any UM server, you must first remove all Exchange 2007 UM language packs except the en-US language pack (because it can't be removed). You must do this because of the differences between the speech services platform included with Exchange 2007 and the platform used for speech services and SIP signaling in Exchange 2010 SP2. For more information about the new UM language packs that are available, see New Unified Messaging Functionality and Voice Mail Features in Exchange 2010 SP1.

To check which UM language packs are installed, run one of the following commands.

• To see a list of all the language packs that are installed on a specific UM dial plan, run:
  
  

  	Copy Code
  Get-UMDialPlan identity MyUMDialPlan |FormatList

• To see a list of all the UM language packs installed on a single UM server, run:
  
  

  	Copy Code
  Get-UMServer -identity MyUMServer |FormatList

For more information about how to remove a language pack from a UM server, see How to Remove a Unified Messaging Language Pack from a Unified Messaging Server.

After you've removed all the language packs, install the Exchange 2010 SP2 version. For details, see Upgrade Exchange 2010 UM Language Packs from RTM or SP1 to Exchange 2010 SP2.

Important:
If you have multiple UM dial plans in your organization, we recommend that you remove all UM language packs from each of the UM servers that are associated with a single dial plan. After you remove these language packs, you can install the prerequisites and Exchange 2010 SP2 and then install the SP2 UM language packs on each UM server.

For more information about UCMA, see UCMA 2.0 Core Architecture or Overview of Unified Messaging.

After you've removed the Exchange 2010 RTM UM language packs from the UM servers, you can download and install Exchange 2010 SP2 on each UM server. You use the Microsoft Exchange Server 2010 Service Pack 2 Setup wizard to install Exchange 2010 SP2.
