Unified CCE (Unified Contact Center Enterprise) is a Cisco product that provides a comprehensive, multichannel customer contact solution. It includes a set of software and hardware components that work together to provide advanced call routing, contact management, and reporting capabilities.

Unified CCE is the core platform on which other Cisco products like Enterprise Chat and Email, Exception Queue and Supervisory Queues are built upon. It is the foundation of the contact center infrastructure and it's unable to be deleted or made inactive as it provides the foundation for other Cisco products.

It's important to note that the specific requirements for the contact center infrastructure may vary depending on the version of CCE and the specific requirements of the organization. It's recommended to consult the Cisco documentation and your Cisco support team for further assistance.
