This (514) 315-6779 number looks as if it is on a trunk, and that is why they get dead air, actually it connects and hangs up within 3 seconds.I just got a call from this number and did some digging.  They were looking to "verify" my information, claiming they were from Yellow Pages Group. They didn't have any information to verify to me that they were yellow pages group. THis is why I became suspiciose.  I asked for a number to call them back at, she gave me another yellow pages group real 800 number in which I called.  They did know this was going on, and complimented me on catching on.   This telemarketer claiming they are yellow pages group is trying to collect information, and verify's who has authority at the business they call ( Yes Your cell might be listed as a business number) once they verify the info, well, collect it, they send a bill.  Not sure what they actually do, if anything, but it is a scam.

A woman ask me for be listed in the yellow page, we are a company ... She books me a rendez-vous with a saller ...I will cancel that. I try to phone, but no ring!

missed call from them

I have the same call but I din't answer, I try to call them back but they hang up on me several time,so  don't answer to those scammers

They phoned, I answered, they hung up. How professional.

Hi, it's not a scam, the number belongs to Synergik, a company our of Montreal, Quebec. They are apparently hired by Yellow Pages to update database information on companies. You don't actually get any bills, etc.
