Introduction to ps-locale-zh_TW-12.5.1.4000-1.cop.sgn
The ps-locale-zh_TW-12.5.1.4000-1.cop.sgn is an official localization component for Cisco Unified Communications Manager (CUCM) 12.5.1, developed to deliver full Traditional Chinese language compliance for enterprise collaboration systems in Taiwan. Released under Cisco’s Q2 2025 software updates, this package implements Big5 encoding support and regional formatting standards across administrative interfaces, call detail records, and endpoint displays.
Validated for hybrid deployments integrating on-premises CUCM clusters and Cisco Webex Calling services, the software ensures accurate rendering of Traditional Chinese characters (繁體中文) on Cisco IP Phone 7800/8800 series and Webex Room Kit Pro endpoints. It adheres to Cisco’s _ naming convention (zh_TW), supporting compliance with Taiwan’s National Communications Commission (NCC) regulations and CNS 11643 standard for enterprise communications.
