Madoff, pictured in 2010, is serving a 150-year sentence at a federal prison in North Carolina and had to call collect to speak with a CNN Money reporter.

The convicted Ponzi schemer, who is currently serving out a 150-year sentence from a North Carolina prison had to call collect, because his prison phone account at Butner Federal Correctional Complex was low on funds.

In the interview, Madoff also recounted his new life in prison, saying that he works "a few hours a day" on the prison's telephone and computer systems, earning him a prison salary of $40 a week. He pleaded guilty in 2009 for taking an estimated $65 billion from investor s in one of the most complex pyramid schemes in history.
