[Asterisk-biz] answering machine detection

[mattf]

Ben Hencke released this piece of code a couple weeks ago, I'd intended to
play around with it, but as always I got swamped and haven't been able to
touch it.

Thanks for the urls, maybe i'll see if i can code something like that.  
  Since i was hoping for someone working on the code, -dev is the best 
place for this.  Especially since I plan on developing the code myself, 
one way or another :)

Have to correct myself. Apparently it *is* possible to detect based on
voice frequency patterns.
