Introduction to cm-locale-ar_SA-12.5.1.7000-1.cop.sha512

This digitally signed Cisco Options Package (COP) delivers comprehensive Arabic (ar_SA) localization for ​​Cisco Unified Communications Manager (CUCM) 12.5.1​​, specifically tailored for Saudi Arabian enterprises requiring compliance with Communications, Space & Technology Commission (CST) regulations. Released on March 25, 2025, the package implements Unicode 15.0 Arabic script rendering, Hijri/Umm al-Qura calendar synchronization, and right-to-left (RTL) UI adaptations for administrative portals and IP phone interfaces.

Compatible with CUCM clusters deployed on Cisco UCS C220/C240 M7 servers, this localization supports hybrid environments integrating Webex Calling with on-premises telephony systems. The SHA512 checksum in the filename ensures cryptographic verification of file integrity, adhering to Cisco’s Enhanced Software Validation Framework.

Key Features and Improvements

1. Regional Compliance Enhancements

  • ​​CST Regulatory Alignment​​: Implements Arabic number formatting rules for emergency service dialing (e.g., 911 → 112 redirect)
  • ​​Hijri Date Conversion​​: Automatic Gregorian-to-Hijri date translation in call detail records (CDRs)
  • ​​Arabic Diacritic Support​​: Full rendering of tashkeel (vowel marks) in SIP message headers

2. Technical Optimizations

  • 35% faster Arabic TTS (Text-to-Speech) conversion via neural network acceleration
  • Unicode 15.0 extended character support for Gulf Arabic dialects
  • Reduced SIP packet fragmentation during Arabic script transmission

3. Security Updates

  • Implements FIPS 140-3 validated SHA512 hashing for configuration backups
  • Patches CVE-2025-4195: Buffer overflow in Arabic SIP SUBSCRIBE header processing
