The method I use instantly hangs up. On Asterisk systems if you don't force an Answer() the call is never fully answered and you are never charged. I didn't explicitly mention this in the article, but this is a good question.

So no, you don't need to do that, although that would be a suitable method. My method requires less load on your PBX as you don't have to send as many SIP packets (and can therefore place more calls and scale your attack better).
