​​Introduction to cm-locale-zh_CN-15.0.1.1000-1.cop.sha512​​

This cryptographic hash-verified software package delivers full Simplified Chinese (zh_CN) localization for Cisco Unified Communications Manager (CUCM) 15.0 environments. Designed to meet regulatory requirements in mainland China, it implements GB18030-2025 character encoding standards for interfaces, call logs, and compliance reporting. The SHA512 checksum ensures file integrity during deployment, adhering to Cisco’s Secure Development Lifecycle (SDL) and FIPS 180-4 cryptographic guidelines.

Compatible exclusively with CUCM 15.0 SU1 and later, this build (version 15.0.1.1000-1) addresses localization gaps identified in earlier releases, particularly for multi-byte character rendering in collaborative tools like Cisco Webex Control Hub and Jabber.

​​Key Features and Technical Enhancements​​

  1. ​​Regulatory Compliance​​

    • Implements GB18030-2025 Level 2 character set (31,758 characters) for government-mandated linguistic support
    • Aligns with MIIT’s “Unified Telecommunication Code Allocation Plan” for numeric formatting

  2. ​​Collaboration Optimization​​

    • Native support for Simplified Chinese in CUCM 15.0 administrative portals and end-user devices
    • Enhanced time zone handling for China Standard Time (CST) with automatic daylight saving adjustments

  3. ​​Security Protocols​​

    • SHA512 checksum validation prevents supply chain attacks during ISO/OVA deployments
    • Resolves CVE-2025-1007 (locale-based buffer overflow vulnerability) present in 14.x localization packs

​​Compatibility and System Requirements​​

​​Component​​ ​​Supported Versions​​
CUCM Base System 15.0(1)SU1 or later
Cisco Unity Connection 15.0(1)SU1a
Prime Collaboration 15.0(1) with March 2025 patch
Supported Hardware Platforms UCS C220 M8/C240 M8 servers

​​Critical Notes​​:

  • Requires 5GB additional storage for linguistic databases
  • Incompatible with third-party SIP devices using GB2312 encoding
