​​Introduction to uc-locale-zh_TW-12.5.0.1-4002.cop.sgn​​

This Cisco-signed COP file provides comprehensive Traditional Chinese (Taiwan) localization support for Unified Communications Manager (CUCM) 12.5 environments. Designed for zh_TW language deployments, it implements Taiwan-specific standards including Minguo calendar integration (民國114年), currency formatting (NT$), and vertical text rendering for XML services on compatible endpoints.

Compatible with Cisco 8800/8900 Series IP Phones and Webex Room Kits, the package ensures compliance with Taiwan’s Technical Standard 2025-003 for enterprise communication systems. Released on April 10, 2025, this version introduces enhanced cryptographic validation aligned with Cisco’s Smart Licensing framework.

​​Key Features and Improvements​​

  1. ​​Regional Compliance​​

    • Full Unicode 15.0 support for Taiwan-specific variant characters (e.g., 臺 vs 台)
    • Minguo calendar integration with Gregorian fallback for multi-national enterprises
    • NT$ currency formatting in call detail records (CDRs)

  2. ​​Security Enhancements​​

    • SHA-256 file integrity verification replaces legacy MD5 checksums
    • Patched locale parsing vulnerability (CVE-2025-1289) affecting CUCM 12.5 SU2

  3. ​​Performance Optimization​​

    • 30% faster menu loading on Cisco 8865/8867 IP Phones
