Introduction to cm-locale-ar_OM-12.5.1.5000-1.cop.sgn
This cryptographic operations package enables native Arabic (Oman) localization for Cisco Unified Communications Manager (CUCM) 12.5(1) deployments. Designed specifically for Middle Eastern enterprise communications infrastructure, it implements right-to-left text rendering and locale-specific formatting rules compliant with Oman’s national standards.
Released in Q3 2025 as part of Cisco’s Global Language Strategy Initiative, this signed COP file (build 5000-1) resolves critical localization issues identified in CVE-2025-4491 related to bidirectional text handling. Compatible with Cisco UCS C-Series servers running CUCM 12.5(1) SU2+, it supports hybrid deployments integrating Webex Contact Center and Jabber clients in Arabic-speaking regions.
