Configuring the V2IU 4350
—Any: for the specified network, allows all ports and protocols through the system. No ports are required because not all protocols support the concept of ports.
•Port or Port Range: The port number or port range allowed through the system when UDP or TCP are selected. A port range is specified by separating the starting and ending ports with a colon ':' (for example, 22:80). The ports parameter is not supported when you select Any protocol because not all protocols support the concept of ports.

Peering Proxy
H.323 prefixes can be used to route calls based on a matching prefix in the destination alias of the call. Each prefix is associated with a domain name or IP address to send the call to in case the prefix matches.
The prefixes are searched in order, that is, the first prefix is tried first, and then the next one on the list until the system finds a matching prefix. This means that if there are multiple matching prefixes, the first one is used.
How Peering Proxy Works
The Polycom V2IU 4350 supports the concept of an H.323 Peering Proxy. This function provides advanced security layers or peering points within the network where a security layer is needed. Peering Proxy allows network providers to add internetworking connections between their “trusted” network and an unknown network. This topology hides their trusted network and the Stateful packet inspection Firewall provides the policies to ensure security. You can add Peering Proxies in series with one another to push the core H.323 networking infrastructure to meet individual security requirements.
The illustration below shows a sample diagram with dial plan and call flow examples. It is a snapshot of how the Peering Proxy can be deployed. Peering Proxy however, is not limited to this specific scenario, so contact your Polycom representative to discuss specific network requirements for full Peering Proxy support.
