call from this number is annoying, it rings at least 25 times, I have caller ID so DO NOT Answer, how do we stop them from calling.

Received call with nobody on the line and then line went dead. Called back and spoke to someone (medic alert) and they advised me that they would take me off there do not call list. I told him that this would be the fifth time I have been told this and he apologized to which I again asked him to ensure my name is taken off thier list which would be better than any apology!

They called me and when I answered they hung up. Didn't say a word

I also got a call from this #. Why call me?

Selling security systems for elderly. Have had many calls from these jerks. not elderly, but decided to follow through this time, and pressed 1 as directed, hoping to go ape on someone. Instead it hung up on pressing 1I think the vile sob's are just sneakily finding out if you're elderly.

Called just before 8:00 pm. Something about a senior's lifeline. On DNC list.  I pressed 1 to talk to a rep and when he came on the line I blew my old referee's whistle into the phone.  Highly recommended technique.
