Configuring the V2IU 4350

The IP PBX in the corporate headquarters location performs VoIP signaling and the 4350 acts as a proxy for the voice devices installed at the branch office. Please note that in the configuration the 4350 located at the Headquarters location is acting as a WAN router only. The 4350s installed at the brand offices perform the following functions in this application:

WAN/LAN IP routing.

Traffic shaping and priority queuing to guarantee high quality voice traffic. These mechanisms protect voice and data traffic from contending for the same network resources to guarantee low latency and the highest call quality possible for VoIP traffic. At the same time they ensure the best utilization of WAN bandwidth by enabling data traffic to burst up to full line rate in the absence of voice calls. Precedence is automatically given to traffic coming from IP phones and other devices using the 4350’s Application Layer Gateway function.

NAT/PAT translation for IP phones and PC’s. This allows a single 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.

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 and test tools.
