Introduction to Cisco_Meeting_Server_3_7_1_vSphere-6_5.ova

This Open Virtual Appliance (OVA) template enables streamlined deployment of Cisco Meeting Server 3.7.1 on VMware vSphere 6.5 environments, providing a secure foundation for enterprise video conferencing infrastructure. Released in Q4 2024 per Cisco’s documentation update cycle, the package optimizes resource allocation for hybrid collaboration workflows while maintaining backward compatibility with CMS 3.5+ clusters.

Designed for UCS M5 V2 servers and VMware ESXi 6.5+ hypervisors, this virtualization package supports integration with Webex services and third-party platforms like Microsoft Teams through native SIP interoperability. It resolves 18 CVEs identified in previous CMS versions while introducing FIPS 140-3 validated encryption modules.

Key Technical Enhancements

1. Virtualization Performance Upgrades

  • ​​vSphere 6.5 Optimization​​: Reduces VM memory footprint by 22% through ESXi-native resource pooling
  • ​​Autoscaling Clusters​​: Supports dynamic addition of up to 24 nodes without service interruption
  • ​​OVF Parameter Preconfiguration​​: Embeds default settings for CPU reservations (8 vCPU) and memory allocation (32GB)

2. Security & Compliance

  • ​​TLS 1.3 Readiness​​: Maintains fallback to TLS 1.2 while preparing for upcoming encryption standards
  • ​​STIR/SHAKEN Authentication​​: Validates caller identities in cross-platform SIP sessions
  • ​​FIPS 140-3 Modules​​: Meets U.S. federal requirements for cryptographic implementations

3. Cross-Platform Interoperability

  • Microsoft Teams Direct Routing via SIP Gateway
  • WebRTC 1.1 support for browser-based participants (Chrome 98+, Edge 101+)
  • Cisco Webex App 42.8+ integration with persistent meeting spaces
