1. ​​Introduction to Cisco_Meeting_Server_3_4_2_vSphere-6_0.ova​​

Cisco_Meeting_Server_3_4_2_vSphere-6_0.ova is a preconfigured virtual appliance template designed for deploying Cisco Meeting Server (CMS) 3.4.2 on VMware vSphere 6.x hypervisors. This Open Virtualization Archive (OVA) file streamlines the implementation of secure, scalable conferencing solutions by integrating CMS components—Call Bridge, Web Bridge, and XMPP server—into VMware’s enterprise virtualization ecosystem.

Targeted at hybrid collaboration architectures, this release supports 500-1,000 concurrent HD video sessions (720p/1080p) while maintaining backward compatibility with legacy SIP/H.323 endpoints. It aligns with Cisco’s Unified Communications Manager (CUCM) 14.x and Webex Hybrid Call Service for centralized administration.

​​Current Version​​: 3.4.2 (March 2025 release, per Cisco’s quarterly feature update cycle).

2. ​​Key Features and Improvements​​

2.1 Enhanced WebRTC Capabilities

  • ​​4K Content Sharing​​: Supports Ultra HD screen sharing via WebRTC-enabled browsers (Chrome 95+, Firefox 90+).
  • ​​Adaptive Bitrate Control​​: Dynamic adjustment (256 Kbps – 8 Mbps) based on network QoS metrics.

2.2 Security Upgrades

  • ​​FIPS 140-2 Compliance​​: AES-256 encryption for SIP/TLS and SRTP media streams.
  • ​​Role-Based Access Control (RBAC)​​: Granular permissions for 12 admin roles via Cisco Meeting Management (CMM) 4.1 integration.

2.3 Scalability Optimizations

  • ​​Resource Pooling​​: Auto-distributes CPU/RAM across 3-32 node clusters using vSphere DRS.
  • ​​vSAN Support​​: Reduces storage latency by 40% through VMware vSAN 6.7 U3 integration.
