​​Introduction to Cisco_Meeting_Server_3_3_3_vSphere-6_0.ova​​

Cisco_Meeting_Server_3_3_3_vSphere-6_0.ova is a preconfigured Open Virtual Appliance (OVA) template designed for deploying Cisco Meeting Server (CMS) 3.3.3 on VMware vSphere 6.0 environments. This enterprise-grade collaboration platform enables secure video conferencing, web-based meetings, and real-time communication across hybrid networks.

The software integrates Cisco’s on-premises conferencing capabilities with VMware’s virtualization infrastructure, offering IT administrators a scalable solution for managing virtualized collaboration workloads. The “3_3_3” version identifier signifies incremental updates to performance optimizations, security patches, and compatibility refinements over previous releases.

​​Key Features and Improvements​​

​​Enhanced WebRTC-Based Collaboration​​

The CMS 3.3.3 release strengthens browser-first meeting experiences through:

  • ​​Multi-Screen Web App Support​​: Participants can split meeting content (e.g., video feeds, shared documents) across two displays without third-party plugins.
  • ​​Granular Host Controls​​: Administrators can lock meetings, mute participants globally, or designate “important” attendees during sessions.

​​Security and Compliance​​

  • ​​TLS 1.3 Encryption​​: All signaling and media streams adhere to updated cryptographic standards for data-in-transit protection.
  • ​​Smart Licensing Integration​​: Centralized license management via Cisco Meeting Management (CMM) reduces manual activation steps and improves audit compliance.

​​VMware vSphere 6.0 Optimization​​

  • ​​Resource Efficiency​​: Reduced CPU overhead (15–20% compared to earlier versions) for stable operation on ESXi 6.0 hosts with constrained hardware.
  • ​​OVF Tool Compatibility​​: Supports both vSphere Client (HTML5) and legacy Flash-based interfaces for deployment flexibility.
