Michael,

Thank you or your response. So it is my responsibility to do whatever needs to be done while mod_avmd attempts to detect a beep and to manually stop it after a beep as been detected or after a certain timeout. Correct?

Bernard,

Keep in mind that avmd is non-blocking, that is, it won't cause your dialplan or script to pause while it is attempting to detect the beep. Your dialplan will keep doing what it normally does, and if avmd detects a beep then it will throw an event which you catch and handle in your onInput function.

Hello,

I'm trying to use it from a Lua script. My understanding is that mod_avmd detects beep from voicemail systems and is CPU intensive, please correct me if I'm wrong.

The Lua example at FreeSWITCH Wiki is
local human_detected = false;
local voicemail_detected = false;

function onInput(session, type, obj)
if type == "dtmf" and obj['digit'] == '1' and human_detected == false then
human_detected = true;
return "break";
end

if type == "event" and voicemail_detected == false then
voicemail_detected = true;
return "break";
end
end

session:setInputCallback("onInput");
session:execute("avmd","start");
In order to implement this example, the script must wait for the beep to be detected or not to process the case accordingly. What is no beep is detected? How can I prevent called party to hear only silence while potential beep detection is being executed?

Thank you

Bernard
