Introduction to cm-locale-fr_CA-12.5.1.4000-1.cop.sgn Software

This localization package provides native Canadian French language support for Cisco Unified Communications Manager (CUCM) 12.5.1 systems, designed to meet CRTC (Canadian Radio-television and Telecommunications Commission) 2024 regulations for bilingual telecommunications infrastructure. Released in Q1 2025, it resolves linguistic formatting conflicts in administrative portals and compliance reporting tools, specifically addressing Québec’s Charter of the French Language (Bill 101) requirements. Compatible with CUCM clusters running 12.5(1)SU3+ on Red Hat Enterprise Linux 8.7 derivatives, it implements CSA Group CAN/CSA-ISO 8601:2024 standards for date/time formatting.
