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

This cryptographic hash-verified locale package provides Czech (Czech Republic) language support for Cisco Unified Communications Manager (CUCM) 14.0(1), addressing compliance with Czech Telecommunications Office (ČTÚ) Directive 2025/03 for regional numbering plans and localized administrative interfaces. Released on ​​July 10, 2025​​, it implements ISO 8601-CZ date/time formats, E.164 numbering adaptations for the +420 country code, and UTF-8 encoding for Czech diacritical characters (e.g., č, ř, ž).

Embedded SHA512 validation ensures FIPS 180-4 compliance for secure enterprise deployments, validating file integrity during distribution. Designed for multinational enterprises operating in Central Europe, it supports Cisco IP Phone 7800/8800 Series, Webex Desk Pro, and Jabber endpoints.

​​Key Technical Enhancements​​

  1. ​​Regional Telephony Compliance​​

    • Implements ČTÚ’s mandatory call detail record (CDR) formatting for +420 national numbering.
    • Supports dual-alphabet directory services with Czech-specific sorting rules (háček-accented characters prioritization).

  2. ​​Security Validation​​

    • SHA512 checksum prevents tampering via 1024-bit block processing and 512-bit message digest.
    • Aligns with ISO/IEC 10118-3 cryptographic standards for government-grade deployments.

  3. ​​Performance Optimization​​

    • Reduces Czech text rendering latency by 19% compared to CUCM 12.5(1) locale packs.
    • Optimizes memory allocation for multi-language interfaces (max. 2.8GB RAM utilization).

​​Compatibility Requirements​​
