1. Product Overview

The ​​ps-locale-ar_EG-12.5.1.5000-1.cop.sgn​​ file serves as the cryptographic validation package for Cisco’s Arabic (Egypt) localization resources in Collaboration Suite 12.5(1). Designed for Middle Eastern deployments, this SHA256-signed container delivers RTL (Right-to-Left) text rendering, Egypt-specific regulatory compliance, and Islamic calendar synchronization across Cisco’s Unified Communications ecosystem.

Released under Cisco’s Q4 2025 Software Maintenance Window, this package aligns with Egypt’s NTRA cybersecurity regulations while supporting Unicode 14.0 Arabic script requirements.
