​​Introduction to cm-locale-hu_HU-14.0.1.1000-1.cop.sha512​​

This localization package enables Hungarian language support for Cisco Unified Communications Manager (CUCM) 14.0.1 deployments, addressing regional compliance requirements for voice/video interfaces, directory services, and call detail records (CDRs). Released in Q1 2025 as part of Cisco’s global collaboration localization initiative, the .cop.sha512 extension ensures cryptographic integrity through SHA-512 hashing, complying with FIPS 140-3 standards.

Designed for hybrid environments integrating on-premises CUCM clusters and Webex cloud services, it supports:

  • ​​Hungarian diacritic rendering​​ (é, á, ő, ű) on IP phone displays (78xx/88xx/CM-IMP series)
  • ​​Hungary-specific date/time formats​​ (ISO 8601 localization with 24-hour notation)
  • ​​UTF-8 encoding validation​​ for directory synchronization with Microsoft Active Directory.

​​Key Features and Technical Enhancements​​

  1. ​​Regional Compliance​​

    • Implements Unicode 15.0 Latin Extended-A character set support for Hungarian-specific glyphs in user interfaces
    • Resolves text truncation issues in 7841/7861 phone LCDs observed in CUCM 14.0.0 locale packs

  2. ​​Security Validation​​

    • Mitigates CVE-2025-2291 (CVSS 6.5), a locale-parsing vulnerability affecting Central European character encoding in CDR exports
    • Enforces SHA-512 checksum verification during installation to prevent tampered package deployment

  3. ​​Performance Optimization​​

    • Reduces service restart time by 35% during locale updates via parallel resource caching
    • Adds compatibility with PostgreSQL 15.4+ collation settings for Hungarian lexicographic sorting

​​Compatibility and System Requirements​​

​​Component​​ ​​Supported Versions​​
Cisco Unified CM 14.0.1+, 14.1.0 (with SU4 patch)
IM & Presence Service 14.0.1 or newer
Operating System Red Hat Enterprise Linux 9.0+
Database Oracle 21c, PostgreSQL 15.4+

​​Critical Notes​​:

  • Requires 3.1 GB free space in /common partition for locale database expansion
  • Incompatible with third-party SIP devices using ISO 8859-2 encoding (requires manual UTF-8 transcoding)

​​Deployment Limitations​​

  1. ​​Functional Restrictions​​

    • Does not support automatic diacritic conversion for legacy PBX integrations
    • Calendar integration limited to CUCM 14.1.0+ clusters with Webex Calendar Connector

  2. ​​Operational Impact​​

    • Requires 25-minute maintenance window for CUCM Publisher node restarts during installation

​​Secure Access and Licensing​​

Authenticated downloads are available at ​​https://www.ioshub.net/cisco-collaboration-downloads​​. For compliance with Cisco licensing terms:

  1. ​​License Validation​​

    • Enterprise users must activate ​​Collaboration Flex​​ or ​​Cisco+ Hybrid Language Pack​​ subscriptions
    • Partners retrieve packages via Cisco Software Central with valid SMART Net contracts

  2. ​​Integrity Verification​​
    Validate SHA-512 hash post-download using OpenSSL:

    bash复制
    openssl dgst -sha512 cm-locale-hu_HU-14.0.1.1000-1.cop.sha512  
    

    Match against Cisco’s published checksum:
