Prior to mod_avmd getting updated, I would call avmd with the “start” command and find the detection in javascript via:
function onDTMFOrEvent(s, type, obj, arg)

{

   try {

        if(type == "event" && session.getVariable("avmd_detect") == "TRUE")

        {

            console_log("info", "Voicemail Detected\n");

            //session.execute("avmd", "stop"); //Deprecated

            session.execute("avmd_stop");          

            return false;

        }

   }  catch (e) {

      console_log("err", e + "\n");

   }

   return true;

}

The key line was if(type == "event" && session.getVariable("avmd_detect") == "TRUE"), but the new documentation mentions the “beep detected” event name which can be subscribed with “event plain CUSTOM avmd::beep” which will have the Beep-Status custom field which should have “DETECTED” .

Finding that particular event and status is not straightforward. I cannot use obj.Beep-Status as that is invalid JS. Does the “avmd_detect” session variable continue to get populated as before?
