Obvious scammer with poor English pretending to be from the "US Treasury."

Just scare the pants off him by telling him that in 10 minutes, his magicJack device will be disabled and his number taken out of service.

Yes, it's yet another cowardly scammer using a magicJack and pretending to be from the IRS.

You, and I, BOTH know that this will not not stop these hardened scammers, and criminals,. but your comment is  appreciated as humorous.

Sadly, you are right.  

But, if you, yourself, are determined enough, there does seem to be a way to determine (plus or minus CID spoofing and number portability issues) on a VoIP line, whether a caller is using a device or service (such as a magicJack) that is commonly used by scammers.  However, you need to have and to be able to program PBX software (such as Asterisk) or buy an add-on module that performs a lookup in a database of telephone number blocks to find the name of the company to which a particular number is assigned.  This information might replace the caller name (CNAM) information on your phone when real CNAM information is not otherwise available.

Perhaps someday I can try this project and let you know whether I can get it to work.  But it's not likely to be anytime soon.  In the meantime, it might be worth dropping a line to your carrier to ask them to provide the caller's carrier name when CNAM is not available.

Got a call Friday.  You could tell it was
a scam because he didnt ask for person he was calling
