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

The ​​cm-locale-fr_CH-12.5.1.6000-1.cop.sgn​​ is an official Cisco localization package enabling Swiss French language support for Cisco Unified Communications Manager (CUCM) 12.5.1 deployments. Released on May 10, 2025, this COP file provides full linguistic adaptation for Switzerland’s bilingual regions, including Geneva and Vaud, through ISO 639-3 compliant fr_CH translations.

Designed for multinational enterprises and Swiss government agencies, it integrates with CUCM’s administrative interfaces, device locales (e.g., Cisco IP Phone 8865), and Webex Hybrid Services portal. The package supports UTF-8 character encoding and complies with Swiss Federal Office of Communications (OFCOM) regulations for telecommunications systems.
