Introduction to cm-locale-ar_EG-12.5.1.7000-1.cop.sha512

This cryptographic locale package provides specialized Arabic language support optimized for Egyptian regional standards in Cisco Unified Communications Manager (CUCM) 12.5(1) environments. Released in Q3 2025, it implements Unicode 15.1 Arabic script rendering rules and complies with Egypt’s National Telecommunications Regulatory Authority (NTRA) localization mandates for enterprise communication systems.

The software maintains compatibility with Cisco UCS C-Series servers (C220/C240 M7) and virtualized deployments using VMware ESXi 8.0 U3+ or KVM 6.5+ hypervisors. It resolves 15 localization issues identified in previous CUCM versions, including bidirectional text alignment improvements for Webex Calling interfaces and Hijri/Gregorian calendar synchronization enhancements.
