Introduction to uc-locale-cs_CZ-14.0.0.1-83.cop.sha512

This localization package delivers comprehensive Czech (cs_CZ) language support for ​​Cisco Unified Communications Manager (CUCM) 14.0.1​​, enabling full UI translation across administrative portals, IP phone interfaces, and diagnostic logs. Released in Q4 2024 under Cisco’s Central European Localization Program, it complies with Unicode 15.0 standards for Central European diacritic rendering (e.g., “č/ě/ř”) on 7800/8800 series IP phones and Webex Calling clients.

The SHA512-verified bundle integrates with Cisco’s hybrid collaboration architecture, supporting both on-premises deployments and Webex Cloud-Connected UC environments. Designed for CUCM 14.0.1 base installations, it maintains compatibility with Cisco Collaboration Flex Plan 3.0 licensing until the platform’s scheduled End-of-Support (April 7, 2027).
