asterisk users - Jun 2009 - ADM v. homemade code

Hi, 

I am attempting to implement Answering Machine Detect and have also played
with using BackgroundDetect instead. Does anyone recommend one over the
other? Here is the code I am using for the BackgroundDetect method (from
voip-info.org).

Thanks.

   [detect] 
   exten => s,1,Set(MACHINE=0) 
   exten => s,2,Answer 
   exten => s,3,BackgroundDetect(silence/5, 1000, 50) 
   exten => s,4,Noop(answering machine detected) 
   exten => s,5,Set(MACHINE=1) 
   exten => s,6,BackgroundDetect(silence/30, 1000, 50, 30050) 
   exten => s,7,Noop(too long of a message) 
   exten => s,8,Hangup 

   exten => talk,1,GotoIf($[${MACHINE}=1]?2:3) 
   exten => talk,2,Goto(detect-machine,s,1)       ; this is a machine 
   exten => talk,3,Goto(detect-human,s,1)       ; this is a human

I do see that AMD.conf offers more parameters, but my initial testing has
had vastly varying results. (I meant "AMD" in the subject line. :/)

Thanks again.
