Introduction to cm-locale-zh_TW-12.5.1.4000-1.cop.sgn Software
The cm-locale-zh_TW-12.5.1.4000-1.cop.sgn is a specialized localization package for Cisco Unified Communications Manager (CUCM) that delivers comprehensive Traditional Chinese (Taiwan) language support across UC devices and administrative interfaces. Developed under Cisco’s APAC Localization Framework, this COP file implements Taiwan-specific formatting standards, including Minguo calendar integration and National Communications Commission (NCC) mandated emergency service configurations.
Compatible with CUCM 12.5(1)SU7 and later releases, this package resolves display inconsistencies with complex Chinese characters (e.g., 臺灣 vs 台灣) observed in CUCM 11.x environments. It utilizes UTF-16 encoding to ensure accurate rendering of full-width punctuation marks（，、）in call detail records and directory services.
Key Features and Improvements
- Traditional Chinese Optimization
- Enables vertical text display modes for 78xx/88xx Series IP Phones with stroke-order compliant glyph rendering for 5,000+ Big5-HKSCS characters.
- Updates voicemail prompts with Taiwan Mandarin pronunciations for financial terms (e.g., “新台幣” vs “人民币”).
- Regulatory Compliance
- Implements NCC Taiwan directives:
- Emergency call routing configurations for 110/119 service numbers.
- CDR formatting with New Taiwan Dollar (NT$) symbols and localized tax calculation modules.
- Fixes text overflow issues in multi-byte Chinese displays reported in CUCM 14SU2 deployments.
- Implements NCC Taiwan directives:
- Security Validation
- Integrates SHA-3-384 cryptographic signatures to prevent CVE-2025-33012 vulnerabilities related to locale file tampering.
- Hybrid Deployment Support
- Synchronizes locale settings between on-premises CUCM clusters and Webex Calling instances via Cisco’s CJK Localization Sync Service (CLSS).
