Highly scalable solution enhances networking and security.

The Polycom V

IU 5300-S series is an easily deployed network appliance solution that provides greater 

scalability than other server-based software solutions. And it helps reduce costs by simplifying the 

deployment, management, and security of converged video, voice, and data networks. 

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

V

IU 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 V

2

IU 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 V

2

IU 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 

V

2

IU 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 

V

2

IU 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. 

Optimizing the quality of your video and voice calls is accomplished by routing video and voice traffic via 

the shortest path possible to minimize jitter, latency, and packet loss.  

The Polycom V
