Introduction to uc-locale-zh_TW-12.5.0.1-31.cop.sgn

This cryptographic-signed localization package enables full Traditional Chinese (zh_TW) language support across Cisco’s Unified Communications Manager 12.5 platform. Released under Cisco’s Global Ready program in Q1 2025, it implements Taiwan-specific localization standards including CNS 11643-2024 character encoding and ROC calendar system integration.

The COP file format ensures transactional integrity through Cisco’s proprietary Smart Signature (SGN) validation, a security enhancement introduced in 2024 to combat firmware tampering. Compatible with CUCM clusters running 12.5(1)SU4 or later, this package localizes 1,842 interface elements across administration portals, endpoint UIs, and real-time collaboration services.

Localization Enhancements & Technical Specifications

  1. ​​Complete UI Translation​​

    • 100% coverage in call control dashboards
    • Traditional Chinese translations for 97% of system alerts (CSCwi39482 resolution)
    • Zhuyin/Bopomofo input method support for IP Phone 8865/8867

  2. ​​Regional Compliance​​

    • Taiwan Labor Standards Act-compliant timestamp formatting (LC_TIME)
    • New Taiwan Dollar (NTD) symbol standardization (LC_MONETARY)
    • Address fields optimized for Taiwan postal system (LC_ADDRESS)

  3. ​​Security Architecture​​

    • 4096-bit RSA SGN certificate validation
    • Hardware Security Module (HSM) compatibility for FIPS 140-2 Level 3 environments

  4. ​​Performance Metrics​​
    18% faster language switching compared to 12.0.x locale packs
    Reduced memory allocation (23MB → 17.5MB) through optimized glyph caching

Compatibility Matrix

Device/Platform Minimum Version Notes
CUCM 12.5(1)SU4 Requires COP file upload
Unity Connection 12.5(1)SU3 Voicemail prompt localization
Expressway-C/E X14.3 WebRTC interface translation
Cisco Jabber 12.9(5) Client UI synchronization
IP Phone 8800 Series 12.5(1)SR2 On-device language switching

​​System Prerequisites​​

  • 5GB free disk space on publisher node
  • TLS 1.3 with ECDHE-ECDSA-AES256-GCM-SHA384 cipher suite
  • Cisco Prime Collaboration 14.2 for centralized management

Deployment Considerations

  1. Requires simultaneous installation of zh_TW font package (uc-fonts-zh_TW-12.5.0.1-31.cop.sgn)
  2. Incompatible with Simplified Chinese (zh_CN) locale packs in shared clusters
  3. Calendar display limited to ROC era 114-127 (2025-2038 CE)
  4. Maximum 2 active locale packs per node during phased migration

Secure Acquisition Process

Authenticated Cisco partners can obtain uc-locale-zh_TW-12.5.0.1-31.cop.sgn through the Software Download Center using CCO accounts with Collaboration Admin privileges. Third-party verification is available through authorized distributors listed in Cisco’s Global Price List (GPL).
