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.<br>

Hello,<br>
<br>
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.<br>
<br>
The Lua example at FreeSWITCH Wiki is<br>
local human_detected = false;<br>
local voicemail_detected = false;<br>
<br>
function onInput(session, type, obj)<br>
if type == "dtmf" and obj['digit'] == '1' and human_detected == false then<br>
human_detected = true;<br>
return "break";<br>
end<br>
<br>
if type == "event" and voicemail_detected == false then<br>
voicemail_detected = true;<br>
return "break";<br>
end<br>
end<br>
<br>
session:setInputCallback("onInput");<br>
session:execute("avmd","start");<br>
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?<br>
<br>
Thank you<br>
<br>
Bernard<br>
