Who I have the same questioned this topic

I am receiving an insane number of international spammer 1 call hangups. This has been reported and is well known by the FCC in the following article:

What i don't understand is why Verizon has no free mechanism to block/filter all calls originating from international and why the board posts keep directing us to a $10/month service. We pay enough for Verizion services. There is a serious problem with the above scam and we should be afforded a free service to block all international calls.
