Introduction to UCSInstall_CUP_14.0.1.12901-1.sha512.iso

This ISO image delivers Cisco Unified Communications Manager IM & Presence Service 14.0(1)SU1, a critical update for enterprises requiring real-time collaboration features like instant messaging, presence status synchronization, and Webex interoperability. Designed for virtualized environments, this release enhances security protocols while maintaining backward compatibility with Cisco Unified Communications Manager (CUCM) 14.x deployments.

The SHA-512 cryptographic hash ensures file integrity validation during deployment. Compatible with VMware ESXi 7.0 U3+ environments running on Cisco UCS B-Series servers, this version was officially released on January 15, 2025 as part of Cisco’s Q1 collaboration suite update.

Key Features and Improvements

  1. ​​Enhanced Security Framework​​

  2. ​​Webex Hybrid Services Integration​​

    • Supports Webex App 44.6+ for federated chat history migration
    • Enables presence status sharing between on-premises CUCM users and Webex cloud accounts

  3. ​​Performance Optimization​​

    • Reduces database synchronization latency by 37% through SQL query optimization
    • Supports 25,000+ concurrent presence subscriptions per node (20% capacity increase)

  4. ​​VMware vSphere 8 Compatibility​​

    • Certified for VMware Tanzu Kubernetes Grid integration
    • Supports VM hardware version 21 with NVMe storage acceleration
