Data Sync Overview and Key Settings

The data of the various devices can be updated on VOSS-4-UC, or also directly on the device. Therefore, it is necessary to periodically synchronize cached VOSS-4-UC data with the data on devices.

Consider an example: when an instance of a Unified CM is added to the system, its data is imported and cached. However, when instances are added, updated or removed from the Unified CM, the cached data in VOSS-4-UC becomes out of sync with data on the device.

If data is deleted from Unified CM before it is deleted from VOSS-4-UC, the error “The specified resource could not be found” is displayed. This means the resource is out of sync and VOSS-4-UC may need to re-sync with Unified CM to delete or update it.

The Data Sync feature provides a means to dynamically synchronize cached VOSS-4-UC data with data on devices. The data sync instance is associated with the connection parameters of a device type in VOSS-4-UC.

Supported devices include:

  • HCM-F (if installed)
  • Cisco Unified CM
  • Cisco Unity Connection
  • LDAP
  • WebEx

Individual Add, Update and Delete operations carried out by a data sync instance can be disabled on the user interface. If no operation is selected, the default behavior is maintained.

Refer to the Best Practices Guide chapter on Data Sync for additional considerations when managing your data syncs.
