​​Introduction to cm-locale-zh_TW-12.5.1.6000-1.cop.sgn​​

This locale package enables full Traditional Chinese (Taiwan) language support for Cisco Collaboration Manager 12.5.1 and later versions. Designed for enterprises operating in Mandarin-speaking regions like Taiwan and Hong Kong, it ensures accurate text rendering, date/time formatting, and language-specific telephony features in Cisco Unified Communications Manager (CUCM) and IM & Presence Service.

The 12.5.1.6000-1 build introduces UTF-8 encoding compliance, resolving critical display issues observed in previous versions when handling complex Unicode characters in call logs and voicemail transcripts. Compatible with Cisco Collaboration Suite deployments running on UCS C-Series servers, it requires minimum firmware version 12.5(1)SU3 for proper integration.

​​1. Complete Language Localization​​

  • Translates 98% of CUCM web interfaces including:
    • System administration menus
    • Device configuration templates
    • Real-time call metrics dashboard
  • Supports Taiwan-specific numbering plans through enhanced 886 country code handling.

​​2. Critical Bug Fixes​​

  • Resolved LC_ALL variable conflicts causing service crashes in multi-locale deployments
  • Fixed improper sorting of Chinese character-based directory numbers

​​3. Security Improvements​​

  • Patched locale privilege escalation vulnerability (CVE-2024-20385) affecting CUCM 12.5 initial releases
  • Implemented SHA-256 signature verification for locale file integrity checks
