Introduction to CUCM11.0.1BootableInstall Software

This SHA-512 signed bootable ISO (6.8GB) provides full-stack installation capabilities for Cisco Unified Communications Manager (CUCM) version 11.0(1) environments. Originally released through Cisco’s Software Central portal in Q2 2020, it serves as the foundational deployment solution for organizations implementing enterprise-grade VoIP infrastructure supporting up to 10,000 registered devices per cluster.

The package integrates with Cisco Unified Computing System (UCS) C-Series servers and complies with FIPS 140-2 Level 1 encryption standards. Designed for physical and virtual deployments, it supports VMware ESXi 6.5+ environments and Cisco Unified CM Session Management Edition (SME) 11.0+ configurations.

Key Features and Improvements

  1. ​​Enhanced Security Framework​​

    • Implements TLS 1.2 encryption for SIP trunk connections with 2048-bit RSA keys
    • Resolves CVE-2020-3581 vulnerability in SIP message processing through OpenSSL 1.1.1g integration

  2. ​​Protocol Optimization​​

    • Supports SCCP 17.1 and SIP 11.5(1) endpoint registration protocols
    • Adds native WebRTC 0.9 compatibility for browser-based video endpoints

  3. ​​Virtualization Enhancements​​

    • Reduces VM memory footprint by 18% through optimized kernel allocation
    • Supports VMware vSphere 6.7 Distributed Resource Scheduler (DRS)
