Dear mohamedbineesh,
Allow me to answer as best as I can.
UCCX Standard Edition is quite a limited package, you won't be able to use features like CAD or Silent Monitoring/Recording. You can use Supervisor Desktop, but again, the features are limited, for a full view of features that you can use with Standard Edition, please check the document below:
