[reSIProcate] Hwo to start

[itche]

Hello all,
I want to start developing around reciprocate.
my first goal is to develop a very simple agent that will receive a call from 
a softphone and will respond in a voice massage.
My second goal is to extend that agent to respond to touchtone (DTMF) 
commands.

How to start???
what to download?
I prefer implementing on a windows box.
Thanks in advance.
Isack
