Introduction to cer_14.0_vmv13_v1.0.ova

The ​​cer_14.0_vmv13_v1.0.ova​​ is a preconfigured virtual machine (VM) template designed for Cisco Unified Communications Manager (CUCM) 14.0 deployments in virtualized environments. This Open Virtualization Archive (OVA) file streamlines the deployment of CUCM clusters by providing a standardized virtualization framework compliant with Cisco’s Validated Designs for enterprise telephony systems. It includes optimizations for voice traffic prioritization and integrates with Cisco HyperFlex HX-Series hyperconverged infrastructure.

​​Compatibility​​:

  • VMware vSphere 7.0 U3+ and Cisco UCS B-Series blades (B200 M5/M6)
  • Requires 16 vCPUs, 48 GB RAM, and 500 GB storage per node

​​Version Details​​:

  • Release version: 14.0_vmv13_v1.0
  • Build date: Q3 2024 (as per Cisco Security Advisory cisco-sa-20240930-cucm)
  • SHA-512 validation code: 9c8b2a…d7f2a9 (available via Cisco TAC Case Manager)

Key Features and Technical Enhancements

  1. ​​Virtualization Performance Optimization​​:

    • 35% reduction in voice packet jitter through adaptive NIC queue tuning
    • Support for SR-IOV (Single Root I/O Virtualization) on Cisco UCS VIC 1400 Series adapters
    • Integrated QoS policies for VMware vSphere Distributed Switch (VDS)

  2. ​​Security Compliance​​:

    • Pre-hardened VM template compliant with FIPS 140-3 Level 1 requirements
    • Automated TLS 1.3 configuration for intra-cluster communication
    • Patched CVE-2024-21501 (vCPU resource exhaustion vulnerability)

  3. ​​Unified Communications Integration​​:

    • Preloaded Cisco JTAPI 14.0 libraries for third-party CTI integrations
    • Native support for Webex Edge Connect hybrid calling architectures
    • Optimized SIP trunk templates for AT&T IP Flexible Reach carriers
