Introduction to ps-locale-zh_TW-12.5.1.5000-1.cop.sgn

The ​​ps-locale-zh_TW-12.5.1.5000-1.cop.sgn​​ software package is an official localization component for Cisco Unified Communications Manager (CUCM) systems, providing full Traditional Chinese (Taiwan) language support for administrative interfaces, user portals, and device displays. Released in Q1 2025, this COP (Cisco Options Package) file ensures compliance with updated Unicode 15.0 standards for character rendering and aligns with Cisco’s multilingual accessibility framework for enterprise communication systems.

Designed for CUCM clusters running version 12.5.1 or later, the package supports localized operation across Cisco collaboration products including IP Phones 8800/8900 Series, Webex Room Devices, and Unity Connection voicemail systems. The signed .cop.sgn format guarantees cryptographic validation during installation, as mandated by Cisco’s software integrity policies for all language pack deployments.
