​​Introduction to uc-locale-zh_CN-15.0.0.1-16.cop.sha512​​

This cryptographic hash-verified localization package enables native Chinese (Simplified) language support for Cisco Unified Communications Manager (CUCM) 15.0.0.1 deployments. Designed for enterprises operating in mainland China and Mandarin-speaking regions, it implements GB18030-2022 character encoding standards while maintaining full interoperability with CUCM’s core telephony infrastructure.

The SHA-512 checksum ensures file integrity during distribution, adhering to Cisco’s Enhanced Software Download (ESD) security protocols. Released as part of CUCM’s Q1 2025 software update cycle, this package addresses China-specific regulatory requirements including dual calendar displays (Gregorian/Lunar) and localized taxation formats in call detail records (CDRs).
