1. Introduction to Bootable_UCSInstall_CUP_11.0.1.10000-6.sgn.iso

​​Bootable_UCSInstall_CUP_11.0.1.10000-6.sgn.iso​​ is the official bootable installation image for ​​Cisco Unified Communications Manager (CUCM) 11.0.1​​, designed for bare-metal deployments or virtual machine provisioning on VMware ESXi/vSphere environments. This ISO file contains the complete operating system, middleware, and call processing components required to establish or upgrade on-premises IP telephony infrastructure.

Primarily used by enterprises managing Cisco Unified Communications deployments, this release addresses legacy system compatibility while introducing foundational security frameworks. The 11.0.1 version is critical for organizations requiring extended support for older SIP endpoints and adherence to export-restricted encryption standards.

​​Core Specifications​​

  • ​​Version​​: 11.0.1.10000-6
  • ​​Release Date​​: May 20, 2020 (per Cisco’s software lifecycle documentation)
  • ​​Deployment Model​​: VMware ESXi 5.5+, vSphere 6.0+
  • ​​Use Case​​: New CUCM installations or upgrades from 10.x/11.x systems

2. Key Features and Improvements

a. ​​Security and Compliance​​

  • ​​FIPS 140-2 Validation​​: Supports AES-256 encryption for signaling/media streams in compliance with US federal standards.
  • ​​Export-Restricted (UNRST) Mode​​: Enables deployment in regions with strict encryption import regulations, though irreversible once activated.

b. ​​Legacy System Support​​

  • ​​SIP Endpoint Compatibility​​: Maintains backward compatibility with Cisco 7900 Series IP Phones and third-party SIP devices lacking modern TLS 1.3 support.
  • ​​Mixed Cluster Operations​​: Allows 11.0.1 nodes to coexist with CUCM 10.5+ clusters during phased upgrades.

c. ​​Virtualization Enhancements​​

  • ​​Resource Optimization​​: Reduces minimum VM requirements to 4 vCPUs and 16GB RAM for small-scale deployments.
  • ​​OVA-to-ISO Migration​​: Provides transitional path for organizations shifting from virtual appliances to custom-configured installations.

3. Compatibility and Requirements

​​Component​​ ​​Supported Versions​​
Hypervisor VMware ESXi 5.5+, vSphere 6.0+
UCS Hardware Cisco UCS C220/C240 M4/M5 Series
Storage NFS 3.0+, iSCSI, local disks
Network Switches Catalyst 3850/9300 Series

​​Critical Notes​​
