Cisco VCS Expressway

The Cisco TelePresence® Video Communication Server Expressway (Cisco VCS Expressway) deployed with the Cisco TelePresence Video Communication Server (Cisco VCS) enables smooth video communications easily and securely outside the enterprise.
The Cisco VCS Expressway enables business-to-business video collaboration, improves the productivity of remote and home-based workers, and enables service providers to provide video communications to customers. The application performs securely through standards-based and secure firewall traversal for all Session Initiation Protocol (SIP) and H.323 devices. As a result, organizations benefit from increased employee productivity and enhanced communication with partners and customers.
The Cisco VCS Expressway uses an intelligent framework that allows endpoints behind firewalls to discover paths through which they can pass media, verify peer-to-peer connectivity through each of these paths, and then select the optimum media connection path, eliminating the need to reconfigure enterprise firewalls.
Administrators have a choice of implementing the Cisco VCS Expressway either as an appliance or as a virtualized application on VMware or similar virtual environments, with additional support for Cisco Unified Computing System™ (Cisco UCS™) platforms.
The Cisco VCS Expressway is built for high reliability and scalability, supporting multivendor firewalls, and it can traverse any number of firewalls regardless of SIP or H.323 protocol.
