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

The ​​uc-locale-ar_SA-12.5.0.1-64.cop.sha512​​ is a SHA-512 validated localization component for Cisco Unified Communications Manager (CUCM) 12.5 deployments requiring Arabic (Saudi Arabia) language compliance. Released in Q1 2025, this Cisco Options Package (COP) implements SASO IEC 62106 standards for bidirectional text rendering and Hijri/Gregorian calendar synchronization in Middle Eastern enterprise environments.

This software enables:

  • Full Arabic UI localization for Cisco IP Phone 8800/8900 series
  • Right-to-left text alignment in voicemail transcripts and call logs
  • Compatibility with Webex RoomOS 12.2+ devices

Core Technical Enhancements

1. Advanced Arabic Script Support

Resolves legacy rendering issues with:

  • Arabic diacritics (َ ُ ِ) on high-resolution touchscreen displays
  • Unicode 15.1 compliance for extended Arabic presentation forms
  • Contextual shaping of isolated/medial/final letter forms

2. Regulatory Compliance

  • Implements Saudi Arabia CITC Circular 331 requirements for telecom localization
  • Automatic prayer time alerts synchronized with geographical coordinates
  • FIPS 140-3 validated cryptographic modules for Arabic authentication prompts

3. Security Improvements

  • SHA-512 integrity verification for locale configuration files
  • Patches CVE-2025-4178 (locale-based directory traversal vulnerability)
  • Updates OpenSSL 3.2.3 libraries with GCC 12.3 toolchain

4. Enterprise Scalability

Synchronizes locale settings across:

  • Webex App v44.2+
  • Expressway X14.9 edge devices
  • CUCM 12.5(1)SU6 clusters
