Introduction to uc-locale-cs_CZ-14.0.0.1-28.cop.sha512

The ​​uc-locale-cs_CZ-14.0.0.1-28.cop.sha512​​ is an official localization package for Cisco Unified Communications Manager (UCM) 14.0.0.1 systems, designed to enable full Czech language support (cs_CZ locale) across Cisco collaboration platforms. This SHA512-signed Cisco Options Package (COP) ensures compliance with Czech regional standards for date/time formats, numeric representations, and multilingual interface translations in enterprise telephony deployments.

Released as part of Cisco’s Q4 2024 software maintenance cycle, this package specifically supports:

  • Cisco Unified Communications Manager 14.0.0.1
  • Cisco Unity Connection 14.0.0.1
  • Cisco Emergency Responder 14.0.0.1

Technical Enhancements & Functional Improvements

1. Native Czech Language Integration

  • Translated 2,800+ system prompts including voicemail menus, error alerts, and directory services
  • UTF-8 support for Czech diacritical characters (č, ř, ž, š, ě) in LDAP/Active Directory synchronization
  • ETSI EN 301 068-compliant emergency service labels for Czech 112 emergency calling systems

2. Security & Cryptographic Validation

  • SHA-512 checksum validation (FIPS 180-4 compliant) against file tampering
  • Preconfigured TLS 1.3 parameters for SIP trunk encryption with Czech regional CA certificates
  • Addresses CVE-2024-5868 vulnerability in legacy locale handlers

3. Performance Optimization

  • 40% faster locale-switching latency compared to v12.5 language packs
  • Reduced memory footprint (1.1GB → 780MB) on UCS C220 M6 servers
  • Multi-tenancy support for service providers hosting Czech enterprises
