Out of curiosity, how does your app know when a real human gets on the line...? Do you have a database of the automatic messages ("Please stay on the line while we sip Cognac and chortle") for each company so it doesn't get false positives?
Indeed, we split test Cognac vs other drinks as an indicator of the psychographic profile of operators at various companies. Groupon is all about the rum and cokes, whatever that means.
Kidding! Yeah we play a message so the operators can hit 1 to get their next call.
