Can you explain further what a FXS and FXO port represents in a call process in general?
FXO port - Expects to RECEIVE dialtone and ring voltage FXS port - Expects to PROVIDE dialtone and ring voltage
Or in other words, an FXO port connects to an analogue PSTN line, and an FXS port connects to an analogue telephone.
And FXS port can also connect to an analog CO port of your PBX. An FXO port could connect to an analog extension on your PBX too. Thinking of PSTN lines and telephones can limit the thinking of a newbie to just PSTN lines and analog phones. There are MANY ways you can use FXS and FXO ports to connect devices togather.
