The July 2011 post below is something I found on another website, see below:

Received a call from this number July 2011. Said they were from ATF, American Telephone/Telecommunications something. She was a little rude when I would question her motives. Said they are in charge of all the lines above the phone company and there are new federal laws to reduce my line charge from 16.99 per line to 5.00 per line.

And I personally received the same call to my business line at work on February 2012.  They were a few minor differences, see below:

Call came in on February 2012.  Said they were from ATF.  The gentleman seemed nervous & was stumbling w/words but he could have been a new person.  He kept rambling on about saving all this money per phone call & how much they would be saving us per month but wanted me to be connected to some other person to approve the changes.  While I was on "hold" I could hear everything in the background & there were people talking (I guess on phones to other people) but I could also hear a radio on the background playing some rap music.  I hung up before the connecting party could join the line & they tried to call back 3 times but I didn't answer.  Not sure if it was a scam or not but it just felt sketchy to me so I went w/my instinct.

Yes a scam! My business phone carrier said they're NOT affiliated with them and I requested to put a block on my account to prevent - as it was called back in the day: phone "Slammers".
I would suggest as I  did letting them know you talked with your phone provider who never heard of your co. and if they don't remove my number/and calls I'm reporting "YOU" and your co. to the proper authorities!
Haven't had a call in over 2 weeks - so far. Hope this helps.

I just got a call from this number, they did not leave a message.

Cautiously answered... NYC could be real, but 98% of all phone activity seems to be fraudulent anymore.  Didn't speak, but background clutter noise... I said "five seconds...." and gave it about two. Hung up to speaker, i.e. I could still hear, but they couldn't.  "Sir? This is Monica...." and then she mumbled and hung up.  Clearly a BS call.

YES received the call today...lady was rude and really didn't want to give me any info on the company  called Advantage. I said if she was working to save my company money then why didn't she know my name and what phone company I was with. I just told her there is a lot of scam out there and that I didn't need anyone to call me up and be so rude to me. Thanks but no Thanks

Same scam.  They are now calling themselves Preferred.  Said they were contracted by AT&T.  Asked me how many lines I had, I told him if he was really working contracted by AT&T he would already have that information and I hung up.

JERKS hung up on my business answering machine. Nothing on Caller I.D. but the phone number and that is usually a tip-off since legitimate calls always to give a name.
