I too received a spam call from this number. For those of you that may ask, the term spam does extent to unsolicited phone calls and no longer applies to just email. I'm not sure what the caller wanted, but I'm certain it was something designed to get money from you.
Just got a call from this number, but didn't answer it. Caller-ID said Austin. If service providers allowed customers to create white lists of approved callers, I think this problem would be solved.
