Introduction to ccp-language-pack_26-12.5.1.10000-10.cop.sgn

This 1.8GB Cisco Options Package (released Q3 2024) provides 26-language localization support for Cisco Unified Communications Manager (CUCM) 12.5.1 deployments. Designed for global enterprises requiring ETSI EN 301 549-compliant accessibility, the module enables simultaneous display of multiple character sets including CJK (Chinese-Japanese-Korean) and right-to-left scripts.

Certified for use with CUCM clusters running on UCS C240 M6 servers or later, the language pack implements Unicode 14.0 standards with 98% glyph coverage. It supports hybrid deployments across on-premises CUCM infrastructure and Webex Calling environments, requiring 64-bit Windows Server 2022 for administration consoles.
