I didn't recognize the number so I didn't answer.

It's the IRS scam..."we are filing a lawsuit against you". Five incoming messages on my personal cell, to which only family members have the number. Message is definitely designed to scare law-abiding tax payers. Check IRS website and MainStreamMedia about IRS methods for pursuing "tax cheats".

Had same message

It is a scam From iRRS demanding ninety within 45 min or you are going to have a warrant for your arrest

I got this call from Woodbridge, VA.  It left a message saying: Hello, we been trying to reach you.  This call is officially a final notice from the IRS Internal Revenue Service. The reason of this call is to inform you that the IRS is filing a lawsuit against you.  To get more information about this case file, please call immediately to our department  number 703-763-5362.  The IRS will NEVER call you about a case.  They will ALWAYS send you a written conformation.  GREAT BIG FAT SCAMMERS!! DON'T ANSWER THEIR CALLS!!
