Introduction to uc-locale-en_EX-15.0.0.1-90.cop.sha512

The ​​uc-locale-en_EX-15.0.0.1-90.cop.sha512​​ is an essential localization component for Cisco Unified Communications Manager (CUCM) deployments requiring extended English language support. Designed for multinational enterprises and government entities, this locale pack implements region-specific conventions for English variants used in territories like Gibraltar, Malta, and other Commonwealth nations.

Certified under Cisco’s Global Localization Framework, this SHA512-signed COP file ensures compliance with ISO 639-3 language standards and regional telecommunications regulations. It supports CUCM versions 15.0.0.1-90 and later, addressing localization gaps identified in Cisco’s Q4 2024 Collaboration Software Roadmap. The package includes extended character sets for specialized administrative domains and updated time/date formats aligned with ISO 8601:2024 revisions.
