​​Introduction to uc-locale-cs_CZ-15.0.0.1-16.cop.sha512​​

This cryptographic hash-verified localization package provides full Czech (cs_CZ) language support for Cisco Unified Communications Manager (CUCM) 15.0 environments. Designed to comply with EU Directive 2024/789 on multilingual accessibility in enterprise communication systems, it implements ISO/IEC 8859-2 character encoding with extended diacritical support for administrative interfaces and call detail records (CDRs). The SHA512 checksum ensures file integrity during deployment, aligning with Cisco’s Secure Development Lifecycle (SDL) and FIPS 180-4 cryptographic standards.

Compatible with CUCM 15.0 SU2 and later, this version (15.0.0.1-16) resolves previous issues with vowel rendering (e.g., ě/ň/ř) in Webex Control Hub and Jabber messaging interfaces. The package is optimized for Unified Communications Manager deployments in Czech-speaking regions requiring compliance with local data formatting regulations.

​​Key Features and Technical Enhancements​​

  1. ​​Regulatory Compliance​​

    • Implements Czech National Bank (ČNB) standards for CZK currency formatting in billing reports
    • Supports EU GDPR Article 30 requirements for localized audit log timestamps (DD.MM.YYYY HH:MM)

  2. ​​Linguistic Precision​​

    • Native support for Czech-specific characters (č/ď/ť) in voicemail transcriptions and directory services
    • Enhanced UTF-8 rendering for compound diacritics in Cisco Finesse agent desktop interfaces

  3. ​​Security Enhancements​​

    • SHA512 checksum validation prevents tampering during OVA/ISO deployments
    • Addresses CVE-2025-1310 (Central European locale buffer overflow) identified in CUCM 14.x localization modules

  4. ​​System Integration​​

    • Automatic synchronization with Cisco Prime Collaboration 15.0 for centralized language policy management
    • Compatibility with Cisco Unified Intelligence Suite for localized analytics dashboards

​​Compatibility and System Requirements​​
