I would suggest that WaitForSilence isn't a very good tool to 'make
sure the phone has stopped ringing', especially since it seems like
what you really want is a smart way to detect whether you have a human
on the phone. You may prefer Answering Machine Detection, known in
dialplans as AMD().

If you honestly just want a wait, put in a wait. If somebody starts
talking by saying hello, WaitForSilence() may not be what you want.
Have you recorded some tests and listened back to them?
