Introduction to cm-locale-zh_CN-12.5.1.2100-1.cop.sgn

This official Cisco localization package provides complete Simplified Chinese (zh_CN) language support for Unified Communications Manager 12.5(1) deployments, specifically engineered to meet the regulatory requirements of China’s Cybersecurity Law and GB/T 22239-2019 standards. The software bundle contains 2,100+ localized interface elements across CUCM administration portals, IP phone displays, and voicemail systems, including Mandarin voice prompts optimized for Cisco 8845/8865 IP phones.

Certified for CUCM clusters running versions 12.5(1) SU1 through SU3, the package implements GB18030-2022 character encoding standards for full compatibility with mainland China’s digital infrastructure. The “.sgn” extension indicates cryptographic signature validation through Cisco’s Secure Boot Framework.
