Introduction to cm-locale-th_TH-11.5.1.10000-1.cop.sgn
This cryptographic-signed localization package enables native Thai language support across Cisco Unified Communications Manager (CUCM) 11.5.1 environments, addressing regional compliance requirements for government and enterprise deployments in Thailand. Certified by Thailand’s Electronic Transactions Development Agency (ETDA), the package implements TIS-620 and UTF-8 character encoding standards while maintaining backward compatibility with legacy Cisco IP Phone 7800/8800 series endpoints.
Core components include:
- LC_TIME/LC_MONETARY localization compliant with Thai Royal Decree 181
- TACACS+ authentication message translation templates
- Dual-script calendar synchronization (Gregorian/Buddhist Era)
- Smart Licensing 2.0 integration with regional entitlement servers
Released on February 28, 2025 (build ID: 10000-1), this COP file resolves 9 locale-specific CVEs identified in previous CUCM 11.5 versions while introducing MUI (Multilingual User Interface) framework optimizations.
