Robo calls are illegal. The feds are cracking down, but there are a lot of bad guys out there. So what should you do when you get a prerecorded sales call? Hang up! Do not engage with the calls by 'pressing one for more information'. Even if you just want to confront those who just interrupted your dinner, by 'pushing one' you prove one of these calls can get you to react. That information is considered gold to these guys, and your name will be placed on a suckers list. Then you'll receive even more robo calls.
