​​Introduction to uc-locale-ja_JP-12.5.0.1-64.cop.sha512​​

This cryptographic-signed localization package provides full Japanese language support (ja_JP) for Cisco Unified Communications Manager (CUCM) 12.5 environments. Designed to comply with Japan’s JIS X 0213:2024 character encoding standards, it implements locale-specific formats including yen currency symbols (¥), era-based calendar displays (令和7年), and vertical text rendering for XML services on supported endpoints.

Compatible with Cisco 8800/8900 Series IP Phones and Webex Room Kits, the package integrates SHA-512 file verification to ensure deployment integrity. Officially released on May 10, 2025, it supports CUCM 12.5 SU7 and later versions, addressing the growing demand for localized collaboration tools in Japanese enterprises.
