​​Introduction to ps-locale-zh_TW-12.5.1.5000-1.cop.sgn Software​​

The ​​ps-locale-zh_TW-12.5.1.5000-1.cop.sgn​​ is an official Cisco localization package designed to enable full Traditional Chinese (Taiwan) language support for Cisco Unified Communications Manager (CUCM) 12.5.1 systems. Released in Q3 2025, this COP file addresses Taiwan’s telecommunications regulatory requirements including:

  • ​​Regional Formatting​​: New Taiwan Dollar (NT$) currency symbols and YYYY/MM/DD date formats
  • ​​Big5/Unicode Compatibility​​: Dual character encoding support for legacy systems and modern UTF-8 environments
  • ​​Legal Compliance​​: Alignment with NCC (National Communications Commission) language accessibility mandates

This package integrates with Cisco’s collaboration ecosystem to deliver localized user experiences on IP phones, Webex devices, and administrative interfaces while maintaining global deployment standards.

​​Key Features and Improvements​​

  1. ​​Enhanced Language Support​​

    • Complete localization of 8865/8845 IP phone displays with Traditional Chinese glyph rendering optimizations
    • Simultaneous support for Taiwan-specific punctuation rules and mainland Chinese input methods

  2. ​​Security Enhancements​​

    • Resolves CVE-2025-22741 locale injection vulnerability identified in previous versions
    • Hardware Security Module (HSM) integration for encrypted language resource storage

  3. ​​Performance Optimizations​​

    • 45% faster text rendering compared to 12.0.x locale packages
    • 30% reduction in memory footprint for high-availability cluster deployments

  4. ​​Cross-Platform Compatibility​​

    • Synchronized localization profiles for Webex App 47.2+ and Jabber 14.5+
    • Support for mixed Simplified/Traditional Chinese display modes in multi-regional deployments
