5. Use MyPBX
5.1 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 MyPBX, connect to local PSTN
·SIP Trunk: Connect to remote SIP VOIP service provider server
What are FXO and FXS?
FXS (Foreign exchange Station) is an interface which drives an analog
telephone or FAX machine. FXS interfaces deliver power, provide ringing, and
use FXO signaling. FXS interfaces are what allow you to hook telephones and
other analog devices to your PBX
FXO (Foreign exchange Office) is an interface that connects to a phone line to
supply your PBX with access to a public telephone network. FXO interfaces use
FXS signaling. FXO interfaces allow you to connect your PBX to real analog
phone lines.
