3. Make outbound call
To make an outbound call, we need to add trunk/service provider first. There are two types of
service provider:
Analog Ports: FXO ports of IP04, connect to local PSTN
VoIP: SIP or IAX trunk, connect to remote SIP/IAX server
In the IP04 i am using, the port 1 and port2 are configured as FXO ports, port 3 and port 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 are what allow you to hook telephones to your PBX, and FXO interfaces
allow you to connect your PBX to real analog phone lines.
