However, as far as I can tell, call blocking is not yet available with Call Assistant. There is a link to new features "coming soon" on my CA page on the web, and one of those is call blocking. So hopefully soon.....there is also a link, which I think is new, where you can post your feedback about CA; that is a nice step forward.
Verizon FiOS TV, Internet, and phone
You are definately wrong about this. IOBI still exists and still can be purchased. In fact, when I signed up for the free service "Verizon Call Assistant" a week ago, I received a letter from Verizon indicating that the free service had been added, and I received a second letter indicating that IOBI service had been added to my account for $7.95 a month. I had to phone to get this unwanted IOBI service off my account. VCA seems to provide a subset of the features of IOBI, which still exists as a separate not-for-free account. By the way, Verizon personnel seem to be very confused by all of this. I had to call tech support because a glitch in my voice mail service prevented VCA from working. When I called, the tech support person had never heard of VCA, and had to go talk to her friends to get another tech support phone number for me to call, and that tech support person referred my call to yet another tech support person who finally fixed my problem.
