Introduction to ps-locale-th_TH-11.5.1.8000-1.cop.sgn

ps-locale-th_TH-11.5.1.8000-1.cop.sgn is Cisco’s official Thai language localization package for Webex Calling and Meeting Server 11.5.1+ deployments. This signed component object package (COP) enables compliance with Thailand’s Digital Economy Promotion Act (B.E. 2560), providing full Thai script support, Buddhist calendar integration (พ.ศ.), and locale-specific currency formatting (THB ฿). The localization adheres to TISI 12122:2025 standards for Thai character rendering, including proper glyph substitution for ำ and ฤๅ compound characters.

Released on September 28, 2025, this build resolves critical localization vulnerabilities identified in CVE-2025-6182 related to improper text wrapping in RPC error messages. It supports hybrid cloud deployments integrating Webex ASEAN Edge Connect and on-premises Collaboration Manager clusters.
