Since the numbers recording started before the beep all I got on the answering machine was ......  press 1 to talk to a live licensed agent or press 2 to be removed from this SPECIAL list.  Darn missed that special call.  Going on call block now.

Got a call from this number today. I don't answer when its a number I don't recognize and let it go to the answering machine. They started saying something about health insurance before I hit the off button on the answering machine which automatically hangs up the call.

I got a call from this number today. I didn't answer since I didn't recognize it but I did try calling back from a different, mobile number.  I got a female voice recording that said, "Hello. Thank you for calling.  If you'd like to be placed on a do not call list for the number that called you, please press one now."  I pressed nothing and a few seconds later the same message repeated, offering no other options and no clues to whom that number actually belongs.  It's been added to my T-Lock Call Blocker's list of banned numbers

Caller ID says "MARKET PLACE". Called and hung up on the answering machine.
Yes it is health insurance sales, since this is open enrollment period. Whether its healthcare.gov or off-market sales I don't know. I just know this "healthcare reform" has been a nightmare for me and my family.

Today I had the same exact experience as you did. What a pain.
