I'm in Los Angeles and am in the DNC list. It was a prerecorded message for carpet a cleaning special, whit I've gotten before. After a moment a woman came on the line and when I asked for a call back number, was given 800-550-2929 and when I told her I was on the DNC list, she hung up. When I tries the 800 number, it does not appear to work.
Although my Caller ID said "Out of Area", other sites report CSP Associates, calling from Buckeystown, Maryland, and in one case, the caller stated that he was paid by the Multiple Sclorsis Association of America.
There was only one call, and it came on 2-11-08 @ 18:22 hours.
