Depends on your phone... is it a cell, log into your carrier's account online & block or use an app if you have a smartphone. If it's a land line you can get home phones that'll block numbers or log on to your account to see if you can block.
This is a "spoof" call from telemarketers. This number has been used by several different companies, which none of these companies own the number. I received this call at different times over the last year and each time I answered, it was a different sales pitch on an unrelated product. Waste of time to answer call, and suspicious there may be hackers behind it.
