Hi,

I see that this is solved by setting the "fire_asr_events=true" on the channel via the outbound ESL call handler when a new call comes in.
-----------------
conn.execute ("set", "fire_asr_events=true", uuid, function (res) {
    console.log ("ASR events now visible to inbound observers as well.");
});
-----------------

In combination with "divert_events on", this seems to ensure that these events are visible to both inbound, and outbound ESL scripts.

The following thread lead me to the solution:

Hi,
 I am wondering if it is possible to turn on 'divert_events' in order to get additional event notifications for things like gtalk and DETECTED_SPEECH over an inbound ESL connection?

 I have an outbound ESL application that fields calls for a particular number and runs some simple grammars.  Here I send 'divert_events on', and I am able to see these additional events no problem.

  I also have a 'monitor' application setup in inbound mode, which just listens to 'everything'.  However this inbound application does not see additional events like DETECTED_SPEECH, although it can see the application calls to play_and_detect_speech.  If I try to send 'divert_events on' from the inbound socket I see an error message "ERR not controlling a session", so I guess this is not correct.

  Is there a way to listen for these additional messages over the inbound socket, or not?

 Thanks!
