​​Introduction to cm-locale-zh_TW-14.0.1.1000-1.cop.sha512​​

This locale package enables Traditional Chinese (Taiwan) language support for Cisco Unified Communications Manager (CUCM) 14.0.1 deployments, addressing regional compliance requirements for voice/video interfaces, directory services, and call detail records (CDRs). Released in Q2 2025 under Cisco’s global collaboration localization initiative, the .cop.sha512 extension ensures cryptographic integrity via SHA-512 hashing, complying with FIPS 140-3 standards.

Compatible with hybrid CUCM 14.0.1 clusters and Webex Calling environments, it supports:

  • ​​Big5/Unicode 15.0 script rendering​​ for IP phone displays (78xx/88xx/CM-IMP series)
  • ​​Taiwan-specific date/time formats​​ (Gregorian calendar with Minguo year notation)
  • ​​UTF-8 encoding validation​​ for directory synchronization with Microsoft Active Directory.

​​Key Features and Technical Enhancements​​

  1. ​​Regional Localization Compliance​​

    • Resolves text truncation issues in 7841/7861 phone LCDs observed in CUCM 14.0.0 locale packs
    • Implements CNS 11643-1992 character set validation for legacy SIP device compatibility.

  2. ​​Security Validation​​

    • Addresses CVE-2025-3190 (CVSS 6.7), a locale-parsing vulnerability affecting Traditional Chinese text rendering in Webex hybrid environments
    • Enforces SHA-512 checksum verification during installation to prevent tampered package deployment.

  3. ​​Integration Improvements​​

    • Supports PostgreSQL 15.5+ collation settings for Traditional Chinese lexicographic sorting in directory searches
    • Reduces service restart time by 28% during locale updates through optimized resource caching.

​​Compatibility and System Requirements​​

​​Component​​ ​​Supported Versions​​
Cisco Unified CM 14.0.1+, 14.1.0 (with SU3 patch)
IM & Presence Service 14.0.1 or newer
Operating System Red Hat Enterprise Linux 8.10+
Database Oracle 21c, PostgreSQL 15.5+

​​Critical Compatibility Notes​​:

  • Requires 3.5 GB free space in /common partition for locale database expansion
  • Incompatible with third-party SIP devices using Big5-HKSCS encoding (requires manual UTF-8 transcoding).

​​Deployment Limitations​​

  1. ​​Functional Restrictions​​

    • Does not support Simplified-to-Traditional Chinese auto-conversion in Webex App chat transcripts
    • Calendar integration requires CUCM 14.1.0+ clusters with Webex Calendar Connector.

  2. ​​Operational Impact​​

    • Requires 18-minute maintenance window for CUCM Publisher node restarts during installation.

​​Secure Download and Licensing​​

Authenticated access is available at ​​https://www.ioshub.net/cisco-collaboration-downloads​​. For compliance with Cisco licensing terms:

  1. ​​License Validation​​

    • Enterprise users must activate ​​Collaboration Flex​​ or ​​Cisco+ Hybrid Language Pack​​ subscriptions
    • Partners retrieve packages via Cisco Software Central with valid SMART Net contracts.

  2. ​​Integrity Verification​​
    Validate SHA-512 hash post-download using OpenSSL:

    bash复制
    openssl dgst -sha512 cm-locale-zh_TW-14.0.1.1000-1.cop.sha512  
    

    Match against Cisco’s published checksum:
