CUC sync
----------

.. _19.3.4|EKB-4778:


User-related services such as *unified messaging* or *alternate extension* are only imported when the 
user is added or updated (for example, when updating their first name, last name, or email address). 


* If services are added directly to the user on CUC, for example, when
  adding Unified Messaging or user-related services such as Alternate Extension,
  this service will not be imported when running the next
  full import from CUC. To import these services a model type list must be applied
  to a dedicated Data Sync to target the required model types. A default Model Type list
  **CUCXN Overbuild Resources** exists for this purpose, which includes the following
  model types:
  
  * device/cuc/User
  * device/cuc/UserPassword
  * device/cuc/UserPin
  * device/cuc/AlternateExtension
  * device/cuc/SmtpDevice
  * device/cuc/SmsDevice
  * device/cuc/PagerDevice
  * device/cuc/PhoneDevice
  * device/cuc/HtmlDevice
  * device/cuc/Callhandler
  * device/cuc/CallhandlerMenuEntry
  * device/cuc/CallhandlerTransferOption
  * device/cuc/Greeting
  * device/cuc/MessageHandler
  * device/cuc/ExternalService
  * device/cuc/ExternalServiceAccount


* If making changes on the CUC directly to the schedules, then it is recommended
  that a dedicated sync be created which will pull in the all the Schedule related models
  (4 models) using the MTL **CUCXN Schedules**.

* It is recommended to use the ``CUCXN Exclude ImportUser`` MTL on
  CUC data syncs in order to avoid unnecessary data and slowing the sync time.
