[Freeswitch-users] How best to use event system for many originates with listeners

[Michael Collins]

Chad,

What is your event listener? Just curious. It seems to me that you could do
an inbound event socket to generate the call and then let that call hit the
dialplan and send it to the socket app which in turn would send the call to
your event listener. (I suppose you could even do something like "bgapi
originate sofia/foo/bar at baz &socket("127.0.0.1:8084")" if you wanted to.)
