Installing iPBX to your corporate LAN
iPBX could be installed with the existing data networks. With this configuration, IP Phones may share the same
network drop with computers to eliminate network rewiring costs. Many customers have concerns about the
performance and their data network and potential security level of IP Phones. Here are the suggested topologies
for IT managers to plan IP Telephony with data networks.
2.1
Network Placement for iPBX
By using the existing data network, the investment for wiring of IP telephony can be saved.
2.1.1
Running Parallel with Existing Corporate Firewall
iPBX connects to both the LAN and the Internet, operating entirely in parallel with the existing firewall without
affecting firewall security. It handles SIP signaling and voice media streams; data will pass through existing
firewall. There is no requirement to change security policy for the existing firewall.

You should be able to connect the WAN port of iPBX to the corporate router or core switch, and running in
parallel with corporate firewall. Connect iPBX LAN port to corporate LAN switch, and connect the LAN port to be
with the same subnet with IP Phones.
