Introduction to uc-locale-zh_TW-12.5.0.1-64.cop.sha512

The ​​uc-locale-zh_TW-12.5.0.1-64.cop.sha512​​ is an official Cisco localization package designed to enable full Traditional Chinese (Taiwan) language support in Unified Communications Manager (UCM) 12.5.x environments. Released in Q1 2025 under Cisco’s Global Language Compliance Initiative, this SHA512-verified COP file provides administrative interface translations, localized emergency service protocols compliant with Taiwan’s National Communications Commission (NCC) regulations, and Big5/Unicode 15.3 encoding support for enterprises operating in Mandarin-speaking regions.

Compatible with UCM clusters running 12.5(1)SU12 or later, the package targets government agencies, financial institutions, and healthcare providers requiring zh_TW localization. The “64” version identifier ensures interoperability with Cisco Emergency Responder 12.5(6) and IP Phone 8900 Series devices with FIPS 140-4 validation.
