Introduction to “ciscocm.cer_jtapi.cop.sgn” Software

This cryptographic certificate package enables secure JTAPI (Java Telephony Application Programming Interface) communication between Cisco Unified Communications Manager (CUCM) and third-party applications. Designed for Cisco collaboration environments, it ensures encrypted signaling for CTI (Computer Telephony Integration) workflows like call control, device monitoring, and CRM integrations.

The “ciscocm.cer_jtapi.cop.sgn” file contains a digitally signed security certificate bundle compatible with CUCM versions 12.5(1) and later. Cisco released this critical infrastructure component on March 15, 2025, as part of its quarterly security hardening initiative for collaboration ecosystems. It replaces deprecated SHA-1 certificates with modern SHA-384 encryption to meet NIST SP 800-131A Rev2 standards.

    • Implements Elliptic Curve Digital Signature Algorithm (ECDSA) with 384-bit prime modulus for TLS 1.3 handshakes
    • Resolves CVE-2025-1147 vulnerability in prior JTAPI certificate chains
    • Supports FIPS 140-3 Level 2 compliance for government deployments

  2. ​​Extended Device Compatibility​​

    • Adds native support for Cisco Webex Edge Connect deployments
    • Validates certificates for hybrid cloud call processing architectures

  3. ​​Operational Enhancements​​

    • Enables automated certificate rotation via Cisco Prime Collaboration
    • Reduces JTAPI service restart time by 62% during certificate updates
