Since the robots can't respond to that prompt, my phone number rings. They don't even get the opportunity to leave me a voice message. Sure, live spammers can get through but that never seems to happen. And, of course, your doctor / contractor / delivery person knows how to press a number in order to complete the call. I haven't received a spam call in over 2 years.

I can't find an app that does that. Can you provide the name of the app?
