Introduction to cm-locale-lt_LT-12.5.1.4000-1.cop.sgn Software

Certified for Cisco Unified Communications Manager (UCM) Release 12.5(1), ​​cm-locale-lt_LT-12.5.1.4000-1.cop.sgn​​ is a localization package that enables Lithuanian language support for Cisco collaboration systems. This COP file standardizes regional voice prompts, device interfaces, and administrative portals to comply with Lithuania’s linguistic requirements and enterprise communication standards.

Officially released in March 2025, this version (12.5.1.4000-1) integrates ISO 8601-compliant date/time formats and Lithuanian-specific numeral conventions. It supports UCM clusters running 12.5(1) SU2 or later, including IM and Presence Service nodes requiring locale synchronization.
