This has happened several times, answer the phone and nothing on the other end, then a busy signal.
Whoever it is doesn't have the guts or courtesy to answer. This needs to be stopped

If you don't recognize the calling number, answer then immediately hang up.  You are, in effect, hanging up on THEM.  It seems to work for me, they don't call back.

It's a telemarketers.  I am on the do not call list. Do you have to re register every year.  They are selling some sort of senior services.  Don't answer.

I received a call from this number this afternoon.  Answered it and it was a recording; something senior citizens being injured.  

You should not have to register every year.  If you are on the no call list you should not be rece4iving these calls.  I grew tired of getting solitication calls from recordings and have started to report each one to my state (missouri) Attorney General.  They've made it easy - it can be dfone right on line.  Check your own state to see if they have something similar.

That said, all too often tese calls are coming from companies that are "spoofing" the caller ID phone number, and that is not the actual number they are calling from.  A few years ago I submitted a writting complaint about receiving such calls to the AG.  I heard back a few months later - the caller ID was spoofed and the source was off shore where they could not be touched,  Very discouraging.
