Walkthrough: Run the Exchange UM Integration Utility

Topic Last Modified: 2009-07-15

To integrate Office Communications Server with Exchange Unified Messaging, you must run the Exchange UM Integration Utility (OCSUMUtil.exe). The utility has two functions:

  • Create contact objects for all defined Exchange Unified Messaging subscriber access and auto-attendants. These objects are needed to route incoming subscriber access and auto-attendant calls to Exchange Unified Messaging.
  • Verify that the Exchange Unified Messaging SIP dial plan names match the corresponding Office Communications Server location profiles. This functionality is needed to enable the routing of outgoing calls from Exchange Unified Messaging to Office Communications Server and to ensure that the correct number normalization is performed. The tool does not correct any mismatches; it only displays them.

The tool is installed on Office Communications Server, Front End Server, at %programfiles%\Microsoft Office Communications Server 2007 R2\Support\ocsumutil.exe.

To run the Exchange UM Integration Utility

  1. On a Server Front End Server, open a Command Prompt window, and then go to C:\ProgramFiles\Common Files\Microsoft Office Communications Server 2007 R2\Support\.

  2. At the command prompt, go to the location of the utility. Type Ocsumutil.exe, and then press ENTER.

  3. Click Load Data in order to find all trusted Exchange forests.

  4. In the SIP Dial Plans list, select a UM SIP dial plan for which you want to create contact objects, and then click Add.

  5. In the Contact box, accept the default organizational unit, or click Browse to start the OU Picker. In the OU Picker box, you can select an OU and then click OK, or you can click Make New OU to create a new organizational unit under the root or any other OU in the domain (for example, "OU=RTC Special Accounts,DC=fourthcoffee,DC=com"), and then click OK.

  6. In the Name box, either accept the default dial plan name or type a new user-friendly name for the contact object that you are creating. For example, if you are creating a subscriber access contact object, you might simply name it Subscriber Access.

  7. In the SIP Address box, either accept the default SIP address or type a new SIP address. If you type a new address, it must begin with sip:.

  8. In the Server or Pool list, select the Standard Edition server or Enterprise pool in which the contact object is to be enabled, preferably the pool where users who are enabled for Enterprise Voice and Exchange UM are homed.

  9. In the Phone Number list, select either Enter phone number or Use this pilot number from Exchange UM, and then enter a phone number.

  10. In the Contact Type list, select the contact type that you want to create, and then click OK.

Note

You should create at least one contact for each auto attendant. If you want external access, you also need a Subscriber Access contact and to specify Direct Inward Dial (DID) numbers.

To verify that the contact objects have been created, open Active Directory Users and Computers and select the OU in which the objects were created. The contact objects should appear in the details pane.
