I just had this missed call on my work line. Glad I was not in the office to pick up. I am wondering if this is the scam where they just want you to say yes, as JessicaP referenced above. http://www.omaha.com/money/this-phone-scam-ju ... 0657f1c1c0.html
There seems to be a pattern. I do get a call from a debt collector from Plano a couple times a year, not sure if this could have something to do with them. It's an agency that buys up old debts from banks and tries to collect. The debt they are going for is over 20 y/o...these people will haunt me to hell and back trying to collect this.
