Create a Targeted Model Type List
---------------------------------

If you manage data on Cisco Unified Communications Manager (Unified CM) or Cisco
Unity Connection directly on a regular basis, perhaps for configuration that is
not orchestrated from VOSS Automate, such as media resources, it is recommended to
create a Model Type List and Data Sync specifically targeting the data items you
are managing. This ensures each data sync is highly optimized for the data being
changed on Unified CM directly and minimizing the load on VOSS Automate. To create a
targeted Model Type List:


**Perform these steps**:

1. Log in as Provider level admin or higher.
#. Access the **Model Type List** form (default menu **Administration Tools >
   Model Type List**) and click **Add**.
#. Specify the name of the Model Type List.

   It is recommended to use a naming convention that makes it easy to identity
   the MTL in a list view, such as Unified CM Media Resources.

#. From the **List Type** drop-down, choose the list type:

   * Choose **Include Selected Model Types** if the list of device models you want
     to sync is relatively short.
   * Choose **Exclude Selected Model Types** if the list of device models you want
     to sync is relatively long. Exclude device models that tend to have lots of
     instances, like users, phones, and lines.
   * Choose **Ordered List** if the list of device models you want to sync is
     relatively short and the order in which they are synced matters.

   .. note::

      A data sync will fail if the **List Type** of the Model Type List does not match
      the **Device Type** of the Data Sync.

 
#. Add Model Types to the list of device models that are to be included or
   excluded according to the **List Type** selected.

   See :ref:`view_list_of_device_models` for information on how to see a list of
   available Unified CM and Cisco Unity Connection device models.
