The Polycom VBP Series allows organizations to improve communication, speed decisionmaking, and accelerate execution by extending telepresence and video to users beyond their network. With the Polycom VBP Series, customers, partners, and remote colleagues are now easily and securely incorporated into an extended telepresence and video federation.
The Polycom VBP ST Series supports all standards-based telepresence solutions, video conferencing endpoints and multipoint conference bridges. Using standards-based firewall traversal, secure access is provided to users of Polycom Converged Management Application™ Desktop and Polycom HDX Series telepresence solutions without requiring a Virtual Private Network (VPN).
The Polycom VBP Series improve interaction quality by performing network address translation (NAT) at the IP address boundary, and forwarding video traffic in the shortest path. Performing video traffic management through prioritization, traffic shaping, call admission control, and DiffServ marking/policing, the Polycom VBP Series enables high quality and secure interactions to occur throughout the organization.
To enhance security against external attacks, Polycom VBP solutions fully protect H.323 gatekeepers, video endpoints, and multipoint conference platforms. With an H.323-aware packet inspection firewall that opens and closes TCP and UDP ports as required, the Polycom VBP Series provides H.323 proxies that enable one public IP to serve all the video communications needs. With availability for bandwidths from 1 Mbps to 200 Mbps, the Polycom VBP Series is also configurable for centralized or decentralized dial plans, depending on IT requirements.
