In March of 2016, the Federal Trade Commission settled with an Orlando based company that was making robo-calls to consumers. With the robo-calls, the company was able to make calls at less than one cent each in cost. The company used automated dialing machines with pre-recorded messages. Here is the principle which applies to robo-calls: if the call is a message from someone selling something and you have not given your permission to get calls from that company, the call could be illegal.
