8.1 Information about Using an IP Network
This section explains common IP network information necessary for setting up QSIG networks.
8.1.1 Using a VoIP Network with the PBX
This PBX supports Panasonic KX-NT300 series, KX-NT500 series, and KX-NT265 IP proprietary telephones
(IP-PTs), Panasonic IP softphones, and SIP (Session Initiation Protocol) phones (hardphones and softphones)
for communication on a Voice over Internet Protocol (VoIP) network. These IP telephones can be used as
extensions of the PBX when the local office LAN is connected to other LANs at different locations.
This PBX also enables VoIP communication with PBXs installed at different locations. Since the communication
does not take place over conventional telephone network, the high cost of long distance communication is
virtually eliminated.
To establish a VoIP network, the virtual cards are used according the requirement of the network. For details
about virtual cards, see "4.4 Virtual Cards".
The following diagrams illustrate VoIP network with (i) a remote office LAN and (ii) another PBX installed at
different location.
Note
Panasonic IP Cell Station (IP-CS) units are also supported by this PBX for communication on a VoIP
network. For details, refer to the Quick Installation Guide for the IP-CS.
