I picked up and waited 10 or 15 seconds before a person finally came on the line.  He said he was from the "Home Security Group."  This might be the same company as the (978) 570-2447 that I've gotten a lot of calls from lately.

They called me and said some security thing but then said they would have someone call me in a few minutes

I answered and the called said they were from Home Security Group. I simply hung up

I received a call while s/w another party, so it went ignored... when I returned the call I received a computer generated message that enabled me to discontinue any future calls.

Telemarketer, they are not screaning do not call list, I am on them and I reported them to the bureau, please do the same , put yourself on the goverment do not call list and then report this type of conpanies that do not respect our privacy
