It would be really amazing to have an option to engage with suspected telemarketing callers using Google Duplex.

User experience: * Get a suspected telemarketing call * Ringer silent while the in call UI waits for user to pick up * If ignored, call us picked up and Duplex engages the caller to know about the offer and get other details * Call transcribed; Optionally summarised and saved in cloud for later access by user

What Google gets: * More widespread use of Duplex with associated improvements * Data from telemarketer, voice as well as offers information which can be further analyzed for any beneficial purpose
