I just checked the call log for my home phone line. Only 7 calls since the 17th of December. Wow.
Just a few months back I was getting 10 to 12 per day.

Maybe the upcoming law about robocalls will help even more.
Two of the seven calls I got since the 17th were about my car's warranties are about to expire, and they will close the books if I don't call them back to extend my warranty. If I am bored, I will call them and ask what the warranty will cost to extend the one on my 1986 El Camino with only 369,000 miles on it. The jerks just hang up. I called back and asked whet the warranty was going to cost for my 1985 911 with just 175,000 miles and they hung up again! So they really do not want my business after all.
And for all of you thinking what a land line???
I would kill it in a heartbeat, but my wife wants to keep it. Happy wife, happy life = we have a landline that gets used once or twice per month maximum. For the $4.95 per month, it is still a waste, but a small one.
