Introduction to ps-locale-bg_BG-12.5.1.4000-1.cop.sgn

This Cisco Options Package (COP) provides complete Bulgarian language localization for Cisco Unified Communications Manager (CUCM) 12.5.1 environments, addressing EU Cybersecurity Act 2025 requirements for Eastern European language support in critical communication infrastructure. Designed for enterprises operating in Bulgaria, it ensures accurate rendering of Cyrillic characters with pre-reform orthography (ѣ, ѫ, ѩ) in voicemail transcripts, directory services, and emergency service interfaces.

Certified for CUCM 12.5.1 SU7 and later, the package implements Unicode 15.0 Cyrillic Extended-D specifications while maintaining backward compatibility with existing English/Greek localization frameworks. Released in Q3 2025, it resolves text encoding conflicts in multi-tenant deployments requiring Bulgarian language prioritization under Bulgaria’s Digital Transformation 2030 strategy.
