Introduction to uc-locale-cs_CZ-15.0.0.1-90.cop.sha512

This cryptographic hash-verified COP file delivers Czech (Czech Republic) language localization for Cisco Unified Communications Manager (CUCM) v15.0 installations. Designed for enterprises operating in Central European markets, it enables native Czech interfaces across 27+ collaboration endpoints and administrative consoles, including:

  • Cisco IP Phone 8800/8900 Series
  • Webex Room Kits Pro
  • CUCM Serviceability & Unified Reporting Tools

Released on March 15, 2025, as part of Cisco’s Q1 Language Expansion Bundle (LXC-2025-03), it adheres to ISO 639-1/ISO 3166-1 locale standards (cs_CZ) and supports UTF-8 character encoding for diacritic preservation. The SHA512 signature ensures file integrity validation during deployment – a mandatory requirement under Cisco’s 2025 Collaboration Security Framework.

Key Features and Improvements
