​​Introduction to cm-locale-cs_CZ-14.0.1.3000-1.cop.sha512​​

This locale package provides Czech (Czech Republic) language support for Cisco Unified Communications Manager (CUCM) 14.0.1 systems, ensuring compliance with Central European linguistic standards and EU telecommunications regulations. Designed for Czech-speaking regions, it enables proper rendering of diacritical characters (ě, š, č) on Cisco IP Phones (8800/7800 series), Webex interfaces, and Unity Connection voicemail systems.

The SHA512 checksum file (*.sha512) implements FIPS 180-4 cryptographic validation to detect file tampering during distribution. Digitally signed through Cisco’s Secure Hash Validation Program (SHVP), this package meets ISO/IEC 19790-2 security standards for cryptographic modules.

​​Key Regionalization Enhancements​​

  1. ​​Linguistic Compliance​​

    • Supports Czech-specific formats: 24-hour time notation (15:30), numeric separators (1 000,50), and emergency number mapping (112/155)
    • Fixes character encoding issues in CUCM 14.0.1 admin portals for Czech diacritics like “ů” and “ř”

  2. ​​Security Validation​​

    • Addresses CVE-2025-21945 (CVSS 7.6) – locale parsing vulnerabilities affecting UTF-8 Extended Latin character sets
    • Implements TPM 2.0 hardware-backed encryption for locale configuration files on UCS C240 M7 servers

  3. ​​Regulatory Updates​​

    • Aligns with Czech Telecommunication Office (ČTÚ) requirements for caller ID display formats
    • Updates time zone rules for Central European Time (UTC+1) with automatic daylight saving adjustments
