Introduction to uc-locale-pt_BR-12.5.0.1-64.cop.sha512

The ​​uc-locale-pt_BR-12.5.0.1-64.cop.sha512​​ is a SHA-512 validated localization component for Cisco Unified Communications Manager (CUCM) 12.5 deployments requiring Brazilian Portuguese language compliance. Released in Q1 2025, this Cisco Options Package (COP) implements ANATEL Resolution 715 standards for text rendering, date/time formats, and regional telephony requirements in Latin American enterprise environments.

This software enables:

  • Full Brazilian Portuguese UI localization for Cisco IP Phone 8800/8900 series
  • Automatic currency symbol (R$) formatting in call detail records
  • Compatibility with Webex RoomOS 12.3+ devices

Core Technical Enhancements

1. Extended Latin Character Support

Resolves legacy diacritic rendering issues with:

  • Portuguese-specific characters (ã, ç, õ) on high-resolution displays
  • Unicode 15.2 compliance for extended Latin character combinations
  • Contextual hyphenation rules for compound words

2. Regulatory Compliance

  • Implements Brazilian GDPR-equivalent LGPD data localization requirements
  • Automatic timezone synchronization with Brasília Official Time (BRT/BRST)
  • FIPS 140-3 validated cryptographic modules for localized authentication

3. Security Improvements

  • SHA-512 integrity verification for locale configuration files
  • Patches CVE-2025-4281 (locale-based buffer overflow vulnerability)
  • Updates OpenSSL 3.2.4 libraries with GCC 12.4 toolchain

4. Enterprise Scalability

Synchronizes locale settings across:

  • Webex App v44.5+
  • Expressway X14.10 edge devices
  • CUCM 12.5(1)SU7 clusters
