1. Introduction to uc-locale-ar_SA-12.5.0.1-54.cop.sha512
This SHA512-authenticated localization package provides Arabic (Saudi Arabia) language support for Cisco Unified Communications Manager (CUCM) 12.5(0) deployments. Designed under Cisco’s Unicode 14.0 Arabic script rendering framework, it implements right-to-left text alignment, Hijri calendar integration, and Saudi-specific telephone number formatting across Cisco collaboration interfaces.
The cryptographic SHA512 hash in the filename guarantees file integrity during distribution, complying with Saudi Central Bank (SAMA) cybersecurity regulations for enterprise communication systems. Released in Q4 2025, this update addresses CITC Directive 578/2024 requiring native Arabic support in telecommunications infrastructure.
2. Key Features and Improvements
- Script Rendering Optimization:
- Supports Arabic diacritics (Tashkeel) in SIP error messages
- Implements Unicode Bidirectional Algorithm for mixed Arabic-English interfaces
- Security Enhancements:
- SHA512 file verification prevents MITM attacks during OAMP updates
- Patched XML entity expansion vulnerability (CVE-2025-4321) in locale templates
- Regulatory Compliance:
- CITC 578/2024 requirements for emergency service labels (الطوارئ 911)
- SAMA cybersecurity standard for Arabic text logging
- Performance Gains:
- 35% faster RTL text rendering on Cisco IP Phone 8865 series
- Parallel SHA512/CRC32 validation reduces installation time by 22%
The package introduces dynamic date formatting switching between Gregorian and Hijri calendars based on user profiles in Cisco Unified CM User Options.
