Microsoft Communications Server 2010 includes the Device Update service, which is automatically installed as part of the Web Services role. This service lets you download updates from Microsoft, test them, and then deploy the updates to all the IP phones in your organization. You can also use Device Update service to roll back devices to previous software versions. We recommend that you check for updates every three months.

For information about the Device Update process and components, see Updating Devices, in the Planning Guide.
