i cannot find this option anywhere, and it was one of my favorite features in AOSP froyo/gingerbread. i know there are apps that can do it, i know you can do it with google voice, and i know you can do it through your VZ account page, but i am just wondering if it really is missing from ICS or if i just can't find it. telemarketers have been blowing me up for 3 days now. yes, i am on the do not call list, but that doesn't seem to matter to them. macy's debt collection is has now left 3 voicemails (i have never even shopped at a macy's), and i have gotten 4 calls about an insurance quote in the last hour.
