Tuesday is the next deadline to sign up for Indiana's Do Not Call registry.
Since January, the state attorney general's office said it has received more than 5,000 complaints about telemarketing calls from live operators or prerecorded messages.
One scam includes an automated call offering to lower consumers' credit card interest rates. The scam doesn't provide any service.
Another automated call mentions an FBI report on the number of home break-ins and offers a "free" home security system. The caller will take information and sell it to a for-profit home security company.
Other consumers have received calls from a live operator who says the consumer has won a large sum of money and can claim it by paying a fee.
