i'd actually love a "mark as spam" feature that crowd sources spam lists - just like mobiles are doing now on iOS and Android
Moving this to Planned for v44
Would love to see OIT subscribe to Nomorobo.com's blacklist if possible (not sure what commercial back-end they offer at a price, but there are competitors that might be willing to license if not?) and implement simple blacklist call-dropping at the inbound-DID level as an optional feature. Not sure what regulatory issues ensue from such blocking, I'm no legal expert, but if the client opts-in it sounds reasonable to me!
