On my line I keep getting calls for "Christine Brock" who apparently owes a lot of money to both Chase Bank - and Henry Mayo Hospital. Not to difficult to guess why she defaulted on her cell phone bill.
On the other line I get calls from the Sacramento Jail - from one of the payphones the inmates can get to. I have never accepted one of them (cost of at least $12 just to answer the phone). Entirely possible the former owner of that number is dodging people too.
