Chapter 3: Configuring the 4200
The 4200 is a flexible, easy to use converged network appliance that provides many
critical networking functions for IP based voice and data. It can be installed in
several different VoIP topologies:
At the customer premise for IP Centrex applications
At the station side of enterprise IP PBXs
At the trunk side of enterprise IP PBXs
Most users will follow the steps provided in the “Configuring The Systems Settings”
section of this manual to initially connect the 4200 into their IP network. The
remainder of the configuration can be different based on the application, VoIP
topology and presence of other networking equipment such as firewalls or DHCP
servers. In general, however, the steps used to configure the 4200 are:

Some of the steps are optional depending on your particular application. We have
provided configuration guidelines below for each of the application types supported
by the 4200. Additional application notes can be found on our website at

Configuration Guide For IP Centrex Applications
A typical 4200installation for an IP Centrex
application uses an external router, xDSL or
cable modem to terminate the WAN link from
the service provider. The 4200is then
connected directly to the WAN termination
device and the LAN port of the 4200is
connected to the 7enterprise ethernet local
area network (typically a layer 2 switch). VoIP
signaling is performed in the service provider
network via a softswitch and the 4200 acts as
a proxy for the voice devices installed in the
enterprise LAN. In this configuration a single
public IP address is used to proxy for all of the
IP phones and to route to multiple PC’s
installed on the LAN. This particular example
also uses static NAT entries to route to the publicly addressable servers. The 4200
performs 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
