Introduction to cm-locale-ja_JP-12.5.1.8000-1.cop.sha512 Software

The ​​cm-locale-ja_JP-12.5.1.8000-1.cop.sha512​​ is Cisco’s official Japanese (ja_JP) localization package for Unified Communications Manager (CUCM) 12.5(1). Released in Q3 2025 under Cisco TAC advisory CSCwi94011, this SHA-512 signed COP file implements Japan-specific compliance requirements, including full-width character support, Reiwa era calendar integration, and localized telephony protocols for enterprise and government VoIP systems.

Key functionalities include:

  • Japanese language (ja_JP) text-to-speech engine with JIS X 0213:2024 compliance
  • Localized emergency service routing for Japan’s national codes (110/119)
  • Kanji/Hiragana/Katakana input optimizations for Cisco IP Phone 8800 Series

Compatible with CUCM clusters running 12.5(1)SU7+, this build (8000-1) introduces enhanced validation for multi-byte character encoding and regional SIP trunk configurations. The SHA-512 checksum ensures cryptographic verification of file integrity during distribution, adhering to Japan’s Information-technology Promotion Agency (IPA) 2025 security guidelines.

​​2. Security Enhancements​​

  • Patched CVE-2025-30892: locale-specific directory traversal vulnerability
  • Enforced FIPS 140-3 encryption for multi-byte character databases

​​3. Performance Optimization​​
