DNC is a gold mine for working numbers for scammers. Dropping the LL won't stop the problem. I get plenty of calls on the cell phone as well. You can block them on the cell and you can get a call blocker for the LL. Ours has 3 times as many numbers on the black list as the white list. Go figure.
It appeared to be automated call, and left a message about "free wireless security system" requiring monthly monitoring fee. Not sure if it legit or not.
I answered and a recording told me I'd been selected to receive a free wireless security system. Whats the point of being on the Do Not Call registry when I still receive unwanted calls?
Didn't answer, checked here (800 notes) instead. Will block number. I'm getting about 2 of these types of calls/day. Still trying to convince wife we need to drop our landline and go cellphones only. Will check with landline service provider (Ooma) to see if they can do better than the "Do not call list" which seems to be useless.
