FCC closes a robocaller's loophole

I’m in the U.S. My wife and I get very few spam or robocalls on the landline. Our cell numbers, however, are under constant assault, not just by robocalls, but spam and scam text messages as well. Thankfully, we don’t have cell coverage at home, so all of my spam voicemail, junk texts, and “missed call” notifications arrive about once a week when, I go to the grocery store.

The caller ID spoofers don’t even try very hard. Often, the displayed number isn’t even a valid phone number. I would think those would be easy for the phone company to identify and block.
