Hi,

any idea how to detect fast answer and do something with those calls?
I think that all calls which are answered in 0-2 seconds are answer by machine (fax,automatic secretary etc.)
But how can i implement this into dialplan?

Greetings

use AMD [answer machine detect] or BackgroundDetect. While not perfect, either will detect answer machines most of the time. Pretty decent explanation here:
