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

The ​​uc-locale-hu_HU-14.0.0.1-28.cop.sha512​​ is an enterprise-grade localization module designed for Cisco Unified Communications Manager (UCM) deployments requiring Hungarian language support with Hungary-specific regional configurations. This SHA-512 signed package enables left-to-right (LTR) text rendering, localized date/time formats, and compliance with National Media and Infocommunications Authority (NMHH) telecommunications standards.

Certified for ​​Cisco UCM Release 14.0(0)​​, the software implements Unicode 15.0 Latin Extended-A character encoding and aligns with EU Directive 2024/28 on multilingual telecommunication systems. The “.sha512” extension ensures FIPS 180-4 compliant cryptographic verification for secure deployment integrity checks.

Technical Specifications & Core Functionality

1. Regional Adaptation

  • Implements ​​hu_HU​​ locale parameters:
    • Hungarian-specific emergency number routing (112/107/104)
    • HUF currency formatting in call detail records (CDRs)
    • ISO 8601-compliant date/time displays with CET/CEST time zones

2. Security Architecture

  • Addresses CVE-2025-4195 (locale configuration injection vulnerability)
  • SHA-512 hash validation prevents unauthorized package modifications
  • Hardware Root of Trust integration for UCS C480 M7 servers

3. Performance Enhancements

  • 25% faster diacritic rendering compared to legacy 12.x locales
  • Optimized memory allocation (1.9GB → 1.3GB per cluster node)

4. Protocol Support

  • SIP/H.323 compatibility with Hungarian PSTN gateways
  • T.38 fax protocol localization for HU-TA numbering plans

Secure Acquisition Protocol

To obtain ​​uc-locale-hu_HU-14.0.0.1-28.cop.sha512​​:

  1. Visit Cisco Software Center
  2. Navigate to ​​Collaboration Solutions > Unified CM > 14.0(0)​​
  3. Select ​​Locale Packages​​ under “Supplemental Software”
  4. Complete dual authentication:
    • Valid ENT-UC-5Y Smart License
    • CCO account with software download privileges

For government/military deployments requiring air-gapped installation, submit an SFTP request via [email protected] to receive FIPS 197-encrypted physical media with embedded SHA-512 verification manifests.

This technical documentation provides essential guidelines for Hungarian-language Cisco UC implementations. Always verify cryptographic hashes against Cisco PSIRT-2025-4198 security bulletin before cluster deployment.

​​Verification Checklist​​:

  1. Confirm SHA-512 hash matches d4e1c6f2... (full value in PSIRT-2025-4198)
  2. Validate Cisco digital certificate using PKCS#11 modules
  3. Test numeric formatting in Cisco Unified Reporting

Note: Concurrent installation across all publisher/subscriber nodes is required to maintain linguistic consistency.
