Poly VBP (Video Border Proxy) 6400

This is an end of life product – Please contact our sales team for the up to date models.


The Poly® VBP 6400-S series can reduce costs by simplifying the deployment, management and security of converged video, voice and data networks. NAT(Network Address Translation) and Firewall traversal issues are resolved by performing video and voice NAT at the public/private IP address boundary. This eliminates security risks posed by other traversal methods that ‘tunnel’ or obscure video and voice traffic at the existing perimeter.

The Poly® VBP 6400-S employs a stateful packet inspection firewall in combination with an application layer gateway, providing comprehensive application-aware security. This approach enables the Poly® VBP 6400-S to dynamically provision and close TCP and UDP ports as needed by video and voice endpoints.

Topology hiding is utilized to protect H.323 gatekeepers and multipoint conference units from network-based attacks. Simply install the Poly® VBP 6400-S between your H.323 gatekeeper (or multipoint conference units) and the public IP network to hide their real IP addresses, and increase security.

Optimizing the quality of your video and voice calls is easy, as the Poly® VBP 6400-S routes video and voice traffic via the shortest path possible, to minimize jitter, latency, and packet loss. A dynamic access control list identifies and authenticates video and voice devices as they register with the gatekeeper. This authentication mechanism eliminates the need to manually program IP addresses of valid devices in other firewalls around the perimeter of the data center.

It’s clear that the Poly® VBP 6400-S series is an easily deployed network appliance solution that provides greater scalability than other server-based software solutions. And since it protects critical IP communication components used in the delivery of hosted video or voice services, this is the ideal solution for both enterprises and service providers.
