The Polycom 5300 E-10 helps reduce costs by simplifying the deployment, management, and security of converged video, voice, and data networks. This is the ideal solution for enterprises that need to enhance interoffice connectivity and collaboration, or migrate from ISDN to IP-based network connectivity. In addition, the Polycom 5300-E is a VoIP and video-aware solution that 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. It employs a stateful packet inspection firewall in combination with an application layer gateway, providing comprehensive application-aware security. This approach enables the Polycom 5300 E-10 to dynamically provision and close TCP and UDP ports as needed by video and voice endpoints. The Polycom 5300 E-10 also makes optimizing the quality of your video and voice calls easy by routing video and voice traffic via the shortest path possible to minimize jitter, latency, and packet loss. At the same time, bandwidth not in use by video or voice is made available so that data traffic can burst up to full line rate, maximizing WAN bandwidth. This traffic management, combined with video and voice call admission control, allows the administrator to effectively manage video and voice to deliver a high-quality experience.
