22-Jan-2009 6:37 p.m. This is a credit card number collection scam. The caller ID info is obviously faked; they are trying to find people who do not have caller ID and who are dumb enough to give them their credit card number. They hang up as soon as you ask them what company is calling. They also use other fake phone numbers in the caller ID info.
