Note The tasks in the list reference detailed instructions in the Cisco Unity installation guide and in other Cisco Unity documentation. Follow the documentation for a successful installation.


Determining the Partner Exchange Server

During configuration of the Cisco Unity software, you will be prompted to select an Exchange server for Cisco Unity to connect with. The server is known as the partner Exchange server, or the partner server. You decide now which server you will use as the partner server, based on the following information; you specify the partner server later in the installation process.

When all Cisco Unity subscriber mailboxes will be homed on the same Exchange server, use that server as the partner server.

When Cisco Unity subscriber mailboxes will be homed on more than one Exchange server, consider the following general guidelines for deciding which server to use as the partner server:

All voice messages from outside callers pass through the partner server on their way to user mailboxes. Use an Exchange server based on its ability to handle the additional traffic.

When Exchange is configured for active/active or active/passive clustering, use either an Exchange server outside the cluster or the Exchange virtual server in the cluster.

When Cisco Unity subscriber mailboxes will be homed in both Exchange 2003 and Exchange 2000—regardless of whether they will also be homed in Exchange 5.5—we recommend, for most topologies, that you use an Exchange 2003 server as the partner server. Otherwise, when you upgrade the partner server to Exchange 2003, Cisco Unity subscriber mailboxes will not have access to messages during the upgrade. In addition, you will need to upgrade the Exchange administration software installed on the Cisco Unity server.


Caution When Windows Server 2003 is installed on the Cisco Unity server, you must use an Exchange 2003 server as the partner server.

However, in some cases, an Exchange 2003 server may not be the best choice. Because of the amount of data that passes between the Cisco Unity server and the partner Exchange server, the partner server should be in the same site as the Cisco Unity server. When Cisco Unity subscriber mailboxes will be homed in Exchange on multiple sites and the only Exchange 2003 servers are on remote sites, do one of the following:

Upgrade a local Exchange 2000 server to Exchange 2003 before you install Cisco Unity.

Use an Exchange 2000 server in the same site as the Cisco Unity server.

When Cisco Unity subscriber mailboxes will be homed in Exchange 2003 and/or Exchange 2000 and will also be homed in Exchange 5.5, you must use an Exchange 2003 or Exchange 2000 server as the partner server.

Installing Exchange Software on the Cisco Unity Server

You install Exchange administration software on the Cisco Unity server. The version of administration software that you install must be the same as the version of Exchange installed on the partner Exchange server.

See the applicable section, depending on the Exchange version on the partner server:

Installing Exchange 2003 Administration Software

Installing Exchange 2000 Administration Software

Installing Exchange 2003 Administration Software


Note Cisco assumes that the Exchange environment is already set up and working before the Cisco Unity system is installed.


When Exchange 2003 is installed on the partner server, you install Exchange 2003 administration software on the Cisco Unity server because it includes the Microsoft messaging API (MAPI). MAPI is the application programming interface that Cisco Unity uses to communicate with Exchange for addressing, sending, and retrieving messages.


Caution Do not install Exchange Messaging and Collaboration Services on the Cisco Unity server.

Later in the installation process, you specify the partner Exchange server that Cisco Unity connects with.

Do the following two procedures in the order listed.

To Install Exchange 2003 Administration Software on the Cisco Unity Server


Step 1 On the Cisco Unity server, insert the Exchange Server 2003 disc in the CD-ROM drive.

If the disc does not run automatically, browse to the root directory, and double-click Setup.exe.

Step 2 Click Exchange Deployment Tools.

Step 3 Click Install Exchange System Management Tools Only.

Step 4 On the Install Exchange System Management Tools Only page, scroll down to Step 4 and click Run Setup Now.


Note In early editions of Exchange 2003, Step 3 on the Install Exchange System Management Tools Only page incorrectly listed Windows Server 2003 Administration Tools Pack as required when the operating system is Windows 2000 Server. In later editions of Exchange 2003, this requirement was removed from Help, as explained in Microsoft Knowledge Base article 826966.


Step 5 In the Welcome to Microsoft Exchange Installation wizard, click Next.

Step 6 In the License Agreement dialog box, click I Agree, and click Next.

Step 7 In the Component Selection dialog box, in the Action column, set the actions for the following three components:

Microsoft Exchange 2003

Change the action to Custom.

Microsoft Exchange Messaging and Collaboration Services

Change the action to None.

Microsoft Exchange System Management Tools

Leave the action as Install.


Step 8 Click Next.

Step 9 Follow the on-screen prompts to complete the installation.

Step 10 Restart the server.


To Install Exchange 2003 Service Pack 1 on the Cisco Unity Server


Step 1 On Cisco Unity Service Packs CD 2, browse to the directory Exchange_2003_SP1\Setup\I386, and double-click Update.exe.

Step 2 Follow the on-screen prompts to complete the installation.

Step 3 Restart the server.

Step 4 If you have not already done so, repeat this procedure on the partner Exchange server and on every Exchange 2003 server on which Cisco Unity subscriber mailboxes are homed.


Installing Exchange 2000 Administration Software


Note Cisco assumes that the Exchange environment is already set up and working before the Cisco Unity system is installed.


When Exchange 2000 is installed on the partner server, you install Exchange 2000 administration software on the Cisco Unity server because it includes the Microsoft messaging API (MAPI). MAPI is the application programming interface that Cisco Unity uses to communicate with Exchange for addressing, sending, and retrieving messages.

Later in the installation process, you specify the partner Exchange server that Cisco Unity connects with.

Do the following three procedures in the order listed.

To Install Exchange 2000 Administration Software on the Cisco Unity Server


Step 1 On the Cisco Unity server, insert the Cisco Unity Message Store 2000 disc in the CD-ROM drive.

If the disc does not run automatically, browse to the root directory, and double-click Launch.exe.

Step 2 Click Exchange Server Setup.

Step 3 Follow the on-screen prompts until the Product Identification dialog box appears.

Step 4 Enter the key for Cisco Unity Message Store 2000 from the sticker located on the CD sleeve, and click Next.

Step 5 In the Component Selection dialog box, in the Action column, set the actions for the following three components:

Microsoft Exchange 2000

Change the action to Custom.

Microsoft Exchange Messaging and Collaboration Services

Change the action to None.

Microsoft Exchange System Management Tools

Leave the action as Install.


Step 6 Click Next.

Step 7 Follow the on-screen prompts to complete the installation.

Step 8 Restart the server.


Exchange 2000 Service Pack 3 and the Exchange 2000 Server Post-Service Pack 3 Rollup that is described in Microsoft Knowledge Base article 824282 resolve an intermittent problem with message notification.


Note If Service Pack 3 and the rollup are not installed, Exchange 2000 Server sends extra UDP packets to ports on the Cisco Unity server that are not listening for packets. Such activity is seen by intrusion-detection systems as port scans or attacks.


To Install Exchange 2000 Service Pack 3


Step 1 On Cisco Unity Service Packs CD 2, browse to the directory Exchange_2000_SP3\Setup\I386, and double-click Update.exe.

Step 2 Follow the on-screen prompts to complete the installation.

Step 3 Restart the server.

Step 4 If you have not already done so, repeat this procedure on the partner Exchange server and on every Exchange 2000 server on which Cisco Unity subscriber mailboxes are homed.


To Install the Exchange 2000 Post-Service Pack 3 Rollup


Step 1 On the Cisco Unity Post-Install CD, browse to the directory Exchange_2000_Post_SP3_Rollup\Setup\I386, and double-click Update.exe.

Step 2 Follow the on-screen prompts to complete the installation.

Step 3 Restart the server.

Step 4 If you have not already done so, repeat this procedure on the partner Exchange server and on every Exchange 2000 server on which Cisco Unity subscriber mailboxes are homed.


Installing the Latest Exchange Service Pack and Updates

Install the latest Exchange service pack (if any) and updates that are recommended for use with Cisco Unity. These are the service pack and updates that you downloaded in the "Downloading Software for the Installation" section.

Some Exchange updates can be installed only after a prerequisite service pack has been installed. Install the service pack, if any, before you install updates.

To Install the Latest Exchange Service Pack


Follow the instructions that you printed or downloaded when you downloaded the service pack.


To Install the Latest Exchange Updates


Step 1 Insert the Cisco Unity Post-Install disc in the CD-ROM drive.

Step 2 Browse to each of the applicable directories and install the correct language version of each update: English (ENU), French (FRA), German (DEU), or Japanese (JPN). (For example, if the French version of Exchange 2000 administration software is installed on the Cisco Unity server, install the French version of any Exchange 2000 updates.)

To speed the installation, you may want to:

Install each update at a command prompt by using the /z option, so you do not have to restart the computer after installing each update.

Install each update at a command prompt by using the /m option, so the update installs without displaying any dialog boxes.

Create a batch file that installs all of the updates at once.

Step 3 Restart the Cisco Unity server.


Extending the Active Directory Schema for Cisco Unity

Several changes need to be made to the Active Directory schema for Cisco Unity to work properly.To see the changes that the schema update program makes, browse to the directory Schema\LdifScripts on Cisco Unity DVD 1 or CD 1, and view the file Avdirmonex2k.ldf.

Changes to the Active Directory schema may take 15 minutes or more to replicate throughout the forest. The changes must finish replicating before you can install Cisco Unity.

To Extend the Active Directory Schema for Cisco Unity


Step 1 Confirm that all domain controllers are on line. (The Active Directory schema extensions replicate only when all domain controllers are on line.)

Step 2 On the computer that has the schema master role (typically the first DC/GC in the forest), log on to Windows as a user who is a member of the Schema Admins group.

Step 3 On Cisco Unity DVD 1 or CD 1, browse to the directory ADSchemaSetup, and double-click ADSchemaSetup.exe.

Step 4 In the Active Directory Schema Setup dialog box, check the Exchange 2000 or Exchange 2003 Directory Monitor check box.

Step 5 If you plan to use VPIM Networking or Cisco Unity Bridge Networking, check the applicable check boxes.

Step 6 Click OK.

Step 7 When the schema extension has finished, Ldif.log and Ldif.err files are saved to the desktop. View the contents of the files to confirm that the extension completed successfully.


Creating Organizational Units and a Mailbox Store

Users and distribution lists are created in locations that you specify. If you want users and distribution lists to be created in custom organizational units (OUs), create the OUs now. Both OUs need to be in the same domain, but they do not need to be in the same domain as the Cisco Unity server. For information on creating OUs, refer to Active Directory Users and Computers Help.

You also have the option to create a custom mailbox store as the default for subscribers that are added through the Cisco Unity Administrator or that are imported from a CSV file. For information on creating a custom mailbox store, refer to Exchange System Manager Help. (Later in the installation process, you configure Cisco Unity to use the mailbox store.)
