First, try this
init(Node) ->
{foo, Node} ! register_event_handler,
{event, Node} ! {event, 'ALL'}.
register_event_handler will tell FS to send all events back to the *current* process, so you can get all events by using flush().
2) If you want to coming events send to a dedicated PID, spawn a process and then send the following message in that process
{foo, Node} ! register_event_handler,
IN your case, you might want this:
loop() ->
{foo, Node} ! register_event_handler,
{event, Node} ! {event, 'ALL'},
receive
stop ->
ok;
_Anything ->
io:format("received ~p~n", [_Anything]),
loop()
end.
3) Anyway, try read the freeswitch.erl in the source tree to understand more.
