This phone number called our company.  Our phone system keeps a phone log of all calls.  They had to dial an extension or be transferred to reach 5 different employees in the company, take up anywhere from 15 to 20 minutes of phone time with the employee without the employee knowing of the call.  In some cases the employee was on another call sometime in the middle of the supposed call from this number.  Talk about strange.  I am blocking this area code in our pbx.
