1.1 Overview
1.1.1 Establishing a VoIP Network with the Pure IP-PBX
Panasonic Pure IP-PBX supports Panasonic KX-NT series IP proprietary telephones (IP-PTs), Panasonic
IP
softphones, and SIP (Session Initiation Protocol) Extensions (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.
The Pure IP-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.
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 the Pure IP-PBX for communication on
a VoIP network. However, all of the related information is explained in the Quick Installation Guide for
the IP-CS, and is therefore omitted from this manual.
• In this manual, the illustrations of the PBX are based on the KX-TDE200.
