Caller ID showed OHIO CALL. Didn't leave message. I think this number is "spoofed" I've received several phone calls w/n message left Caller ID may or may not show CUSTOMER RELAT.. a bogus phone number or my phone number! No message but background noise suggests the caller is outside or internet static; recording lasts for 8-13 seconds b4 disconnect.
You have to keep in mind though that the drug addicts and alcoholics that occupy the cubicles don't choose the numbers. They are given a list to call from. It used to be a thick stack of computer printout (I had a friend that used to do this and I visited him at "work" a few times), but I suppose now the numbers are either on a computer screen, or more likely, the computer just automatically calls the next number when the drone pushes a button. No, usually they get fired because they got stoned/high one too many times and didn't show up for work.
