Microsoft provides cabinet files (.cab) that contain software updates for unified communications (UC) devices on the Microsoft Help and Support Web site . As a best practice, you should check this site regularly, at least every three months, for updates that apply to your organization"s devices. You can determine which updates apply to your devices by checking the Device Update Service audit logs to see what versions the devices are currently running. For details, see "To view update and UC device information for your organization," in Auditing Update Requests.

New updates that you obtain from Microsoft Help and Support should apply to your organization"s UC devices, corresponding to their type, brand, model, and language. In most cases, the revision should be more recent than the revision for the last update the UC devices received.

For example, if your organization uses Microsoft Office Communicator 2007 R2 Phone Edition devices with a US English display language, and a software version of 3.5.6887, you should obtain an update with the following characteristics:

Device Type Brand Model Locale Version

UC

Microsoft

CPE R2

DV3

ENU

Later than 3.5.6887, such as 3.5.6897.0

Once you locate the update .cab files that you want, you download the files to your system. From there, you can upload them to Device Update Service.

When a .cab file is uploaded, its data is written to the Windows Management Instrumentation (WMI) data store, and the files it contains are stored in the appropriate file system folders in the DeviceUpdates folder. They are also listed on the Pending Updatestab of the Device Update Service Management Console. When you approve updates, they appear on the Deployed Updatestab, and any device that connects to Device Update Service and requires that update can retrieve it. Until you approve an update, however, only test devices can retrieve it.

After uploading the updates, you should test them prior to deploying them to your organization"s UC devices.

Note:
DeviceUpdates Folder Location.For Office Communications Server 2007 R2 Standard Edition, device update files and Device Update Service audit log files are stored on the local computer in %ProgramFiles\Office Communications Server 2007 R2\DeviceUpdateFiles\DeviceUpdates. For Office Communications Server 2007 R2 Enterprise Edition, you can find the DeviceUpdates folder on the shared updates folder that was created during deployment for client and device update files.
