Just a note of caution about Jolly Roger (http://www.jollyrogertelco.com/), I used to love forwarding spam calls to them. However, since you have to pick up the call to loop Jolly Roger in - the automated system might mark you for repeat calls. For instance I answered a call about student debt repayment or whatever to forward the call and since then I've been getting at least a few calls a week from different numbers about it as well as text messages.
