Introduction to uc-locale-en_GB-12.5.0.1-4002.cop.sgn
The uc-locale-en_GB-12.5.0.1-4002.cop.sgn is a critical localization component for Cisco Unified Communications Manager (CUCM) systems requiring full compliance with UK English language standards and British telecommunications regulations. Developed under Cisco’s European Localization Initiative, this software package enforces British-specific conventions including date formatting (DD/MM/YYYY), currency symbols (£), and emergency service number handling (999/112) for enterprise collaboration systems.
Compatible with CUCM 12.5(0) SU5 and later releases, this COP file addresses Ofcom’s 2025 directives for emergency caller ID localization and GDPR-compliant call metadata management. It supports hybrid deployments integrating Cisco Webex Calling, third-party SIP devices, and legacy ISDN networks operating under UK telecommunications laws.
