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

The ​​ps-locale-zh_HK-12.5.1.4000-1.cop.sgn​​ is a localized software package for Cisco Unified Communications Manager (CUCM) 12.5.1, designed to deliver comprehensive Hong Kong Chinese (Traditional) language support. Released in Q2 2025 under ​​CUCM 12.5.1 Service Update 4​​, this component enables system administrators to deploy regionally compliant interfaces across Cisco’s collaboration ecosystem, including administrative portals, voicemail systems, and endpoint configurations.

Tailored for enterprises operating in Hong Kong SAR, the pack adheres to ​​ISO/IEC 10646:2023​​ standards for Unicode Han character rendering and ​​HKMA Guidelines​​ for financial service communication compliance. It integrates with Cisco Unity Connection, IM & Presence Service, and Emergency Responder to ensure consistent linguistic workflows across voice and messaging platforms.

​​Key Features and Improvements​​

  1. ​​Full Traditional Chinese Localization​​

    • Translates 99% of CUCM interfaces into Hong Kong Chinese, including:
      • Certificate management workflows
      • Real-time call analytics dashboards
      • Multi-level IVR configuration menus
    • Supports ​​Big5-HKSCS​​ character encoding for proper display of Hong Kong-specific glyphs.

  2. ​​Regional Compliance Enhancements​​

    • Implements locale-specific configurations:
      • Date/time formats (YYYY年MM月DD日 HH:mm)
      • Currency symbols (HK$) in call detail records (CDRs)
      • Public holiday calendars for automated system notifications

  3. ​​Security Updates​​

    • Addresses ​​CVE-2025-2167​​, a locale-based directory traversal vulnerability identified in CUCM 12.5.1 SU2.

  4. ​​Performance Optimization​​

    • Reduces UI load latency by 20% compared to legacy Chinese locale packs (v12.0).
    • Optimizes memory allocation for Jabber client synchronization tasks by 15%.
