Received a call from this number on my 800 line. After viewing my call details, it shows that the originating number for this call was from 425-224-1546. This (212-201-7279) is probably a dial around number. I simply went into my settings for my 800 number and blocked both of these numbers. I haven't received any calls from this number in over 3 weeks.
I believe this number is a NY routing number for people calling a toll free number from abroad (Plaetec NY1). There are legitamate calls coming through this routing system. As many know, it is generally not possible to call a US toll free number from outside of the US or Canada. Clearly, scammers can use this system to contact people in the US (and apparently Italy) and block their originating number. As with all things, continue to use your better judgement and protect yourself by blocking any potentially unsafe or unwanted numbers through your service provider.
