Introduction to uc-locale-zh_CN-14.0.0.1-64.cop.sha512

This SHA512-authenticated localization package provides Simplified Chinese (zh_CN) language support for Cisco Unified Communications Manager (CUCM) 14.0 deployments. Designed for enterprise collaboration systems in mainland China, it enables native language interfaces across Cisco IP Phones 8800/8900 Series, Webex Room Devices, and Jabber clients. Released in Q4 2024 under China’s GB/T 18030-2023 character encoding standard, this build complies with the Cybersecurity Law of China for enterprise communication systems.

Key Features and Improvements

  1. ​​Regulatory Compliance​​
  • Implements GB 18030-2023 mandatory character set requirements
  • Supports Simplified Chinese-specific formats including:
    • Lunar calendar integration for scheduling
    • RMB currency symbol positioning (¥ prefix)
    • National standard time notation (24-hour format)
  1. ​​Security Enhancements​​
  • Dual-layer SHA512 verification ensures package integrity
  • 256-bit AES encryption for localized resource files
  1. ​​User Experience Optimization​​
  • Localized system prompts for 50+ CUCM service types
  • Mandarin TTS engine with improved tonal accuracy
  • Stroke-order optimized Chinese character rendering

Compatibility and Requirements

Device Category Supported Models Minimum Firmware
Desk Phones 8845/65/75, 8865/75 14.0.0.19700
Room Systems DX80, RoomKit Pro CE 9.15.4.1
Mobile Clients Webex App v42.8+ Android 12/iOS 16+

​​System Prerequisites​​:

  • Cisco Unified CM 14.0(0)SU1 or later
