1.28 IP Proprietary Telephone (IP-PT) Features
1.28.1 IP Proprietary Telephone (IP-PT)
Description
This PBX supports the connection of IP proprietary telephones (IP-PTs), which function almost identically
to normal PTs. However, they connect to the PBX over a Local Area Network (LAN), and send and receive
calls using Internet Protocol (IP).
IP-PTs have two Ethernet ports for connection, primary and secondary. They are connected to the PBX
through a network hub or other splitting device, and can have a PC connected to the secondary Ethernet
port.
