Introduction to uc-locale-el_GR-12.5.0.1-3000.cop.sgn

This digitally signed localization component provides comprehensive Greek language support for Cisco’s enterprise collaboration ecosystem, specifically optimized for Mediterranean regional deployments. Designed for Cisco Unified Communications Manager 12.5(1) and later versions, it enables native linguistic rendering across administrative consoles, telephony interfaces, and Webex Room Device dashboards in compliance with ISO/IEC 8859-7:2023 standards.

The uc-locale-el_GR-12.5.0.1-3000.cop.sgn file contains 7,200+ translated UI elements and 180+ locale-specific telephony rules validated against ETSI EN 301 140-1 V2.6 specifications. Released under Cisco’s Q3 2024 software update cycle, it resolves critical localization requirements identified in EU government and maritime communication systems.
