[Asterisk-Users] "Say YES to continue" prompts

[Philip Edelbrock]

We're having a problem with call screening with our existing legacy 
system (Toshiba DK40i) which the touch-tone buttons don't work when * 
calls extensions.  At first I had set up a 'press 1 to accept' prompt, 
but it won't work if the DTMF buttons aren't functioning, of course.

So, a thought: Is there a way for Asterisk to listen and hear something? 
  It doesn't have to do voice to text translations or anything so 
complex as that, just sense noise past a threshold and duration.

Mostly, I'm just trying to sense if the user is available and at their desk.

Thanks!
