Just got a call from 415-777-3456. It used to associated with Movie-Phone, but apparently no longer.

If you've been getting calls on a daily basis and no one is on the other end chances are that it is being made from one of those boiler rooms. The computer dials several phones at a time. The person who answers their phone first gets the special treatment--they're treated to a sales pitch.

Me too

No one on the other side. I left it on speaker and they hung up after 10 seconds or so.

These [***] [***].  Who are these people?  Why don't they get a real job?  If you get a call from this number, just know they are scammers,  and they intend to steal all your money and ruin your life, if you let them.  Give them some real [***] over the phone.  They DESERVE it.  They are calling illegally and should be held accountable.  The phone number comes up as MOVIEFONE when you call them back.  If they call you, talk back to them in crazy language, it really [***] with their head.  Say something like.."Why is a mouse when it spins?"  Or, "My desk is eating salad".

Just go to your telephone company web site and BLOCK the offending number, so it will not be able to come thru.
But that's nothing permanent, because those Caller ID spoofers use a number for one day or so, then start to use some other number. The numbers they use are abandoned numbers, not yet reassigned by the telephone companies.
From Wikipedia:

Caller ID spoofing is the practice of causing the telephone network to display a number on the recipient's Caller ID display which is not that of the actual originating station. The term is commonly used to describe situations in which the motivation is considered malicious by the speaker or writer. Just as e-mail spoofing can make it appear that a message came from any e-mail address the sender chooses, Caller ID spoofing can make a call appear to have come from any phone number the caller wishes. Because of the high trust people tend to have in the Caller ID system, spoofing can call the system's value into question.

It is amazing that such a crooked practice is allowed to go on!
Where are the feds when I need them????? I wrote to my US Rep...no response!

Bottom line: IGNORE IT and never give the other side ANY information. PERIOD!

AOL 415-777-3456  calls all day long and hangs up if you don't answer.  So I answered today and aksed who it was.  In a very heavily accented Indian sounding voice, he said, "This is John", something I did not understand, then " This is not a sales pitch." I interupted and  I asked him to take me off the calling list.  We shall see...............
