Introduction to ciscocm.cer_jtapi.cop.sgn
This cryptographic operations package enables secure Java Telephony API (JTAPI) integration for Cisco Unified Communications Manager (CUCM) 12.5(1) environments. Designed to streamline certificate management in multi-vendor contact center deployments, the software pack implements FIPS 140-3 validated encryption for third-party CTI applications.
Officially released in Q1 2025, this signed COP file (build 10000-22) resolves critical vulnerabilities identified in CVE-2025-3355 related to cross-domain certificate validation. Compatible with Cisco UCS C-Series servers running CUCM 12.5(1) or later, it supports hybrid deployments integrating Webex Contact Center and on-premises CUCM clusters.
