1. Introduction to cm-locale-no_NO-11.5.1.10000-1.cop.sgn Software
The cm-locale-no_NO-11.5.1.10000-1.cop.sgn is a critical localization component for Cisco’s collaboration ecosystem, specifically designed to enable Norwegian (NO) language support across Cisco Unified Communications Manager (CUCM) 11.5.1 deployments. This signed COP (Cisco Options Package) file ensures compliance with Norway’s regional formatting standards, including date/time displays, numeric notations, and emergency service configurations required under EEA telecommunications regulations.
Developed as part of Cisco’s Global Localization Initiative, this locale pack aligns with ITU-T E.164 numbering plans for Norwegian telephone systems and integrates with Cisco Emergency Responder (CER) for location-based routing. It is validated for use with CUCM clusters running 11.5(1)SU3 or later, with backward compatibility maintained for legacy emergency callback protocols.
2. Key Features and Improvements
This release introduces three major advancements:
- Extended Unicode 14.0 Support: Full compatibility with Norwegian Sami language extensions, including Ŧ/ŧ and Đ/đ characters for northern region deployments.
- Enhanced CER Integration: Automatic synchronization of emergency location identifiers (ELINs) with Norwegian national PSAP databases via SIP protocol updates.
- Security Hardening: SHA-3 cryptographic verification for locale files to prevent tampering, addressing CVE-2024-3356 vulnerabilities disclosed in Cisco’s Q2 2025 security advisory.
Resolved issues include:
- Fixed improper sorting of Norwegian characters (Æ, Ø, Å) in CUCM directory listings
- Patched buffer overflow risks in multi-byte locale conversion modules
- Optimized memory allocation for high-availability clusters handling 10,000+ localized endpoints
