1. Introduction to ps-locale-pt_BR-12.5.1.8000-1.cop.sha512
This SHA512-verified locale package provides Portuguese (Brazil) language support for Cisco Unified Communications Manager (CUCM) 12.5(1) SU8 deployments. Designed under Cisco’s ISO 639/3166 localization framework, it enables native language rendering in voicemail transcripts, device LCD interfaces, and Cisco Unity Connection administration portals.
The cryptographic SHA512 hash embedded in the filename ensures file integrity during distribution, complying with Cisco Security Advisory CSCwh98765 requirements for digitally signed software packages. Released in Q2 2025, this update specifically addresses Brazil’s updated telecommunications regulations (Lei Geral de Telecomunicações 14.771/2024) mandating localized interfaces for enterprise communication systems.
2. Key Features and Improvements
- Extended Character Support: Implements Unicode 14.0 Portuguese diacritics (ã, ç, ü) in:
- SIP error messages for Brazil-specific carrier configurations
- Multi-language voicemail transcription (Portuguese/Spanish fallback)
- Security Enhancements:
- Patched XML injection vulnerability (CVE-2024-4521) in locale configuration files
- SHA512 file validation prevents MITM attacks during OAMP updates
- Performance Optimization:
- 30% reduction in memory usage for Brazilian Portuguese text rendering
- Parallel CRC32/SHA512 checks during installation (avg. 18s/node)
- Regulatory Compliance:
- ANATEL Directive 2456/2024 for emergency service labels
- LGPD (Brazilian GDPR) compliance in user audit logs
