Grazie Giovanni!


You think I didnt go through that with a fine-toothed comb? 😉

I was looking for some simpler explanations!

I am writing a “call monitor”, something like an operator panel.

I am capturing events via esl in php, filtering down the data and then sending them to a javascript UI via websocket.


My problem is that I am totally bewildered by the amount of events that fs generates, and I’d like to filter it down to a bare minimum.


New outgoing call (with uuid, extension and dialed number)
Call answererd from other party

Line busy

Call hung up from either party.


Can anyone give me a pointer to which events I really need to monitor, and which fields inside?


I will obviously share finished code!
