​​Introduction to cm-locale-ar_OM-11.5.1.8100-1.cop.sgn​​

This locale package provides comprehensive Arabic (Oman) language support for Cisco Unified Communications Manager (CUCM) 11.5.1, addressing linguistic, cultural, and regulatory requirements for enterprises operating under Oman’s Telecommunications Regulatory Authority (TRA) guidelines. Released in Q2 2025, it enables localized user interfaces, date/time formats, and compliance with Gulf Cooperation Council (GCC) telecommunications standards.

The package implements Unicode 15.0 bidirectional text rendering for Arabic script across CUCM administrative portals and endpoints like Cisco IP Phone 8800 Series. It integrates with Cisco’s DST (Daylight Saving Time) synchronization framework, though Oman does not observe DST, ensuring consistent timezone handling for Muscat (Asia/Muscat) across all collaboration services.

​​Key Features and Improvements​​

  • ​​Right-to-Left (RTL) UI Optimization​​: Full Arabic script alignment in CUCM 11.5.1 dashboards and device configuration menus.
  • ​​Hijri-Gregorian Dual Calendar​​: Simultaneous display of Islamic lunar dates and Gregorian dates in call logs and reports.

​​2. Regulatory Compliance​​

  • ​​TRA 2025 Directive Adherence​​: Implements Oman-specific emergency service routing (9999) and carrier access codes (e.g., 00).
  • ​​VAT Formatting​​: Automates 5% Value-Added Tax (VAT) display in billing reports per Oman Tax Authority specifications.

​​3. Linguistic Enhancements​​

  • ​​Dialect-Specific Terminology​​: Supports Omani Arabic dialect variations in voicemail transcripts and IVR prompts.

​​4. Security & Validation​​
