Introduction to cm-locale-th_TH-14.0.1.1000-1.cop.sha512

This cryptographic localization package provides full Thai language support for Cisco Unified Communications Manager (CUCM) 14.x systems. Released under Cisco’s Q3 2025 Software Maintenance Window (SWMW-UC-2025-04), it implements TIS-620/Unicode 16.0 standards for Thai script rendering and integrates Buddhist calendar (BE 2568) compatibility for enterprise deployments in Thailand.

As a COP (Cisco Options Package) file with SHA-512 checksum validation, it requires 1.1GB disk space and supports CUCM clusters running base software 14.0.1.10000-1 or newer. The package aligns with Thailand’s NBTC regulatory requirements for telecom systems.
