Configuring the V2IU 4350

NAT/PAT translation for IP phones and PC’s. This allows a single public IP address to be used on the WAN link to represent all of the private IP addresses assigned to the LAN IP phones and PC’s.

Static NAT entries. This enables the customer to use a WAN public IP address for data servers (web, mail, ftp, etc.) connected behind the 4350. These servers can then be configured with private IP addresses for additional security.

A “VoIP” aware firewall. A full Layer 7 gateway for voice traffic and a stateful packet inspection firewall for data traffic.

Call Admission Control (CAC). CAC uses a deterministic algorithm to decide when there are insufficient network resources available to adequately support new calls and then return the equivalent of a “fast busy” to new call requests.

DHCP server and TFTP relay. These features are used to simplify and expedite the IP configuration of phones and PC’s. This also includes VoIP signaling gateway information (MGCP, SIP, and H.323.

Call quality monitoring (using MOS, jitter, latency, packet loss and much more) and test tools.
