This is the ideal solution for service providers, because it protects critical IP communication components used in the delivery of hosted video or voice services. And it's also ideal for enterprises, because the Polycom® V²IU 5300-S eliminates the need to place H.323 gatekeepers and multipoint conference units on the public IP network for interoffice or partner collaboration.
A VoIP and video-aware solution, the Polycom® V²IU 5300-S series helps resolve NAT/firewall traversal issues by performing video and voice NAT at the public/private IP address boundary, eliminating the security risks of other traversal methods that 'tunnel' or obscure video and voice traffic from existing perimeter security.
The Polycom® V²IU 5300-S employs a stateful packet inspection firewall in combination with an application layer gateway, providing comprehensive application-aware security. This approach enables the Polycom® V²IU 5300-S to dynamically provision and close TCP and UDP ports as needed by video and voice endpoints.
In addition, topology hiding protects H.323 gatekeepers and multipoint conference units from network-based attacks. Simply install the Polycom® V²IU 5300-S between your H.323 gatekeeper or multipoint conference units and the public IP network, to hide their real IP addresses and increase security.
To identify and authenticate video and voice devices as they register with the gatekeeper, the Polycom® V²IU 5300-S uses a dynamic access control list. This authentication mechanism eliminates the need to manually program IP addresses of valid devices in other firewalls around the perimeter of the data center.
The quality of your video and voice calls is optimized by routing video and voice traffic via the shortest path possible, to minimize jitter, latency, and packet loss.
