Matt,
No that’s all mod_vmd does...
If you want to do a more advanced analysis of media stream coming from the client mod_amd is available under a commercial license. This does media analysis to determine machine vs humans based on a hand full of metrics that are tunable. Contact me off list for licensing details

Subject: [Freeswitch-users] mod_vmd--can it do more than simply find VoiceMail Beeping?
I'm doing some outbound dialing, and want to use mod_vmd to detect if a live person picks up or a voicemail picks up. I've read the wiki, and have been playing around with the dialplan implementation and the lua implementation, along with capturing the mod_vmd
vmd::beep event.
Using the examples on the wiki, I am able to call a number, sleep for 25 seconds, and mod_vmd usually detects a Beep (the answering machine beep right before you are to speak your message).
My question is, is there a way to use mod_vmd to detect if an answering machine or human has picked up within the first 1-2 seconds after being answered? If so, can I get an example of how to set this up?
my dialplan to test my lua implementation looks like
<!-- mod_vmd test extension (new mod)--> <extension name="vmdtest"> <condition field="destination_number" expression="^1986$"> <action application="answer"/> <action application="lua" data="matt_vmd.lua"/> <action application="hangup"/> </condition> </extension>
and matt_vmd.lua looks like
print ("--matt_vmd.lua START--") 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 print('MATT--I detected a HUMAN'); human_detected = true; return "break"; end if type == "event" and voicemail_detected == false then print('MATT--I detected a VOICEMAIL'); voicemail_detected = true; return "break"; end end session:setInputCallback("onInput"); session:execute("vmd"); session:sleep(25000); print ("--matt_vmd.lua FINISHED--")
Thanks.
