Introduction to cm-locale-th_TH-14.0.1.1002-1.cop.sha512

The ​​cm-locale-th_TH-14.0.1.1002-1.cop.sha512​​ is an official Thai localization package for Cisco Unified Communications Manager (CUCM) systems, providing full Unicode 15.1-compliant language support for administrative interfaces, user portals, and Cisco collaboration endpoints. Released in Q1 2026, this Cisco Options Package (COP) integrates with CUCM’s Multilingual Framework to enable native Thai language operations in enterprise communication environments.

Designed for CUCM clusters running version 14.0.1 or later, the package supports localized workflows across devices like Cisco IP Phone 8865/8861, Webex Room Kit Pro Series, and Emergency Responder systems. The .cop.sha512 extension guarantees SHA-512 cryptographic verification, aligning with Cisco’s Secure Development Lifecycle (SDL) standards for tamper-proof software distribution.
