Introduction to cm-locale-th_TH-14.0.1.3000-1.cop.sha512

This Critical Options Package (COP) delivers native Thai language support for Cisco Unified Communications Manager (CUCM) v14.0.1 ESR (Extended Stable Release), addressing ASEAN regional compliance requirements under Thailand’s Personal Data Protection Act (PDPA). Officially released on March 25, 2025, the package implements TIS 620-2533 character encoding standards for Cisco collaboration endpoints and administrative interfaces.

The SHA512-verified localization pack resolves 17 Thai-specific display issues reported in CUCM 14.0.1, including proper rendering of complex vowel combinations (如 เ-ีย, เ-ือ) on Cisco IP Phone 8865 and Webex Room Series devices. It supports three regional Thai dialects (Central, Northern, and Southern variants) while maintaining FIPS 140-3 cryptographic validation for secure deployments.
