​​Introduction to cm-locale-uk_UA-12.5.1.6000-1.cop.sgn​​

The ​​cm-locale-uk_UA-12.5.1.6000-1.cop.sgn​​ is an official Cisco localization package enabling Ukrainian language support for Cisco Unified Communications Manager (CUCM) 12.5.1 systems. Released on June 15, 2025, this COP file implements full Cyrillic script compliance (ISO 9:1995 transliteration standard) across CUCM administrative portals, user devices, and API interfaces. Designed for enterprises operating in Ukraine, it addresses language-specific requirements mandated by the National Commission for State Regulation of Communications (NCCIR).

This localization pack supports hybrid deployments integrating on-premises CUCM clusters with Webex Calling services, ensuring consistent Ukrainian UI translations across multi-vendor SIP devices.
