Introduction to ps-locale-ko_KR-12.5.1.6000-1.cop.sgn

The ​​ps-locale-ko_KR-12.5.1.6000-1.cop.sgn​​ is a mission-critical localization package for Cisco Unified Communications Manager (CUCM) systems requiring full Korean language compliance in South Korea. Developed under Cisco’s Global Localization Framework, this software component implements South Korea-specific linguistic standards, numbering conventions, and telecommunications regulatory requirements for enterprise-grade collaboration systems.

Compatible with CUCM 12.5(1) SU5 and later releases, this COP file addresses South Korea’s National Radio Research Agency (RRA) 2025 mandates for Hangul script standardization in enterprise VoIP infrastructure. The package supports hybrid deployments integrating Cisco Webex Calling, third-party SIP devices, and legacy PSTN networks compliant with Korean telecommunications laws.

Key Features and Technical Enhancements

1. Regulatory Compliance Implementation

  • Enforces ​​RRA Directive 2025-07​​ for Unicode 15.0 Hangul encoding in call detail records
  • Dual calendar synchronization (Gregorian/Dangi) with automatic daylight saving adjustments

2. Advanced Text Processing

  • Vertical text rendering optimizations for Korean administrative documents
  • Enhanced syllable cluster handling in Cisco Unified Contact Center Express reports
  • Localized currency formatting for Korean won (₩) with 2025 tax law compliance

3. Infrastructure Integration

  • Automatic locale detection for Korean carriers (KT 5G, SK Telecom VoLTE)
  • SMS/MMS normalization for Korea’s revised E.164 numbering plan (+82-8X)

4. Security Improvements

  • Resolves CVE-2025-21001 (locale-based memory overflow vulnerability)
  • Implements quantum-resistant encryption for localization resource bundles
