6.4 How to make a outbound call
To make an outbound call, we need to add a trunk first. There are two types of Trunk:
•
Analog Ports:
FXO ports of PX0522, connect to local PSTN
•
VoIP Trunk:
SIP or IAX trunk, connect to remote SIP/IAX server
I am using PX0522, the port 1-2 are configured as FXO ports, port 3-4 are configured
as FXS ports. When a port is configured as FXO port, the corresponding LED shows
RED
.
When a port is configured as FXS port, the corresponding LED shows
GREEN
.
What are FXO and FXS?
FXS
(Foreign eXchange Station) is an interface which drives a telephone or FAX
machine. FXS interfaces get phones plugged into them, delivery battery, and provide
ringing. FXS interfaces are signalled with FXO signalling.
FXO
(Foreign eXchange Office)
is an interface that connects to a phone line. They supply your PBX with access to the
public telephone network. FXO interfaces use FXS signalling. FXS interfaces allow you to
hook telephones to your PBX, and FXO interfaces allow you to connect your PBX to real
analog phone lines.
Make call via PSTN trunk
You can use the FXO trunking to make outgoing call via your local PSTN line. The set up
is as per below:
