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

The ​​ps-locale-ko_KR-12.5.1.5000-1.cop.sgn​​ is a critical localization component for Cisco Unified Communications Manager (CUCM) deployments requiring full Korean language compliance in South Korea. Developed under Cisco’s Asia-Pacific Localization Initiative, this software package implements South Korea-specific text rendering, numbering conventions, and regulatory requirements for enterprise unified communications systems.

Compatible with CUCM 12.5(1) SU4 and newer releases, this COP file addresses South Korea’s National Radio Research Agency (RRA) 2024 directives for Hangul script standardization in VoIP infrastructure. It supports hybrid UC environments including Cisco Webex Calling integrations and third-party SIP devices certified for Korean telecommunications networks.
