I've just read through the brainstorm and I would like to see a small addition to solution #2 the addition is specifically about "block calls from specific groups." this should include being able to block incoming calls with numbers hidden. Even though it is against the law (in Germany, don't know about other countries) to call someone with a business matter with a hidden number, still quite a lot of "spam" companies do hide their number. I get quite a few of these calls per month and I just like to completely block those hidden calls and in addition would like them to not show on the "missed calls" entries. Everybody I do have on my contact list and even all of the companies I have a contract with (bank, creditcards, electricity, water etc.) do show their numbers, so I really love to just block those bastards who try to sell me sh*t
