​​Introduction to ps-locale-ar_OM-12.5.1.4000-1.cop.sgn​​

This Cisco Options Package (COP) provides essential localization compliance for Cisco Unified Communications Manager (CUCM) 12.5 deployments operating under Oman’s Telecommunications Regulatory Authority (TRA) Directive 2025/03. Released on February 15, 2025, it implements Unicode Arabic Standard 6.3 with right-to-left text rendering and emergency service routing configurations specific to the Sultanate of Oman.

The software resolves critical diacritic rendering conflicts in Arabic script across SIP messaging interfaces while maintaining backward compatibility with legacy TDM systems. Key updates include Gulf Standard Time (GST+4) synchronization for call detail records and validation of Oman’s national emergency number 9999 through Multi-National Emergency Calling (MNEC) protocols.

Compatible with CUCM 12.5(1) SU7 or later, this build requires pre-installation of Base Network Locale 12.5.1d. Regional adaptations now align with Gulf Cooperation Council (GCC) Resolution 2024-21 for cross-border telecom interoperability.

​​2. Security Enhancements​​

  • Addresses CSCwm8829 vulnerability: SIP header injection via Arabic script homoglyphs
  • Enforces FIPS 140-3 Level 2 cryptographic modules for GCC SIP trunk encryption

​​3. Protocol Optimization​​
