Configuration Outline
Configuration Guide For Station Side IP PBX Applications
Most private enterprise VoIP networks use an IP
PBX at the corporate headquarters location to
provide voice switching between headquarters,
branch offices and the PSTN. The 4300T is used
in these environments to securely connect
branch office employees to the IP PBX installed
in the corporate headquarters location.
The installation of an 4300T on the station side
of an enterprise IP PBX is very similar to the IP
Centrex application above. The branch office is
connected to the corporate network using a
private T1/E1 link connected directly to the WAN
port of the 4300T. The LAN port(s) of the
4300T are connected directly to enterprise
devices and/or Ethernet switches.
The IP PBX in the corporate headquarters
location performs VoIP signaling and the 4300T acts as a proxy for the voice devices
installed at the branch office. The 4300T can perform the following functions in this
application:
 WAN/LAN IP routing.
