[Freeswitch-users] Inbound or Outbound Socket connection?

Thu Oct 13 19:27:15 MSD 2016

Ok David. There are too things here.

I have the dialplan from one side and I have the esl socket from the other
side.

In the dialplan I should call the esl connection somehow to work on that
specefic call in progress. Right?

So how can I make this link without an instruction in the dialplan?

Does this make sence?

You don't need to invoke it, you connect to fs permanently and subscribe to
the events you're interested in. When you get the events, you can get all
the info you want and act accordingly.
