For the past week I have been receiving calls from B2B (minimum of five per day) that I did not answer and finally blocked. After I blocked them I began getting a minimum of five calls per day from home defense which I also blocked. For a couple years now I do not answer any calls that I do not know who they are unless they leave a message on my answering machine. If I receive more than two calls in a week from the same number I then block the number. I was limited in my call block ability until I got the last phone set which allows me to block 250 calls.
