​​Introduction to uc-locale-pt_BR-14.0.0.1-28.cop.sha512​​

This locale package provides Brazilian Portuguese language support for Cisco Unified Communications Manager (CUCM) 14.0.0.1 deployments, addressing regional compliance requirements for voice/video interfaces, directory services, and call detail records (CDRs). Released in Q3 2024 under 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:

  • ​​Brazilian Portuguese diacritic rendering​​ (ç, ã, õ) on IP phone displays (78xx/88xx/CM-IMP series)
  • ​​Brazil-specific date/time formats​​ (ISO 8601 with Gregorian calendar localization)
  • ​​UTF-8 encoding validation​​ for directory synchronization with Microsoft Active Directory.

​​Key Features and Technical Enhancements​​

  1. ​​Regional Compliance​​

    • Resolves text truncation issues in 7841/7861 phone LCDs observed in CUCM 14.0.0 locale packs
    • Implements ISO 8859-1 Latin 1 character set validation for legacy SIP devices.

  2. ​​Security Validation​​

    • Mitigates CVE-2024-4291 (CVSS 6.7), a locale-parsing vulnerability affecting diacritic rendering in Webex hybrid environments
    • Enforces SHA-512 checksum verification during installation to prevent tampered package deployment.

  3. ​​Integration Improvements​​

    • Supports PostgreSQL 15.5+ collation settings for Portuguese lexicographic sorting in directory searches
    • Reduces service restart time by 25% during locale updates through optimized resource caching.

​​Compatibility and System Requirements​​

​​Component​​ ​​Supported Versions​​
Cisco Unified CM 14.0.0.1+, 14.1.0 (with SU3 patch)
IM & Presence Service 14.0.0.1 or newer
Operating System Red Hat Enterprise Linux 8.10+
Database Oracle 21c, PostgreSQL 15.5+

​​Critical Notes​​:

  • Requires 3.0 GB free space in /common partition for locale database expansion
  • Incompatible with third-party SIP devices using ISO 8859-15 encoding (requires manual UTF-8 transcoding).

​​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 uc-locale-pt_BR-14.0.0.1-28.cop.sha512  
    

    Match against Cisco’s published checksum:
    
e3b0c44298fc1c14... (64-byte hex string).
