A legit business would attempt to identify themselves (Caller ID) when a call is made. I received a call from this number and ignored it simply because there was no identifier other than the number. No message was left. My guess a sales call. It seems I get more of these at the end and 1st of the month like these guys are scrambling to meet a call quota.
I had the same experience as Mich above...I answered with the company name and guy says "Oh, I'm sorry I must have the wrong number." Makes you wonder what kind of scam this is.
