Does anyone here know if there is a mobile app available to detect when a human being starts talking on a phone call after you've been on hold for more than 30 minutes? or for any given amount of time for that matter? Unfortunately the reasons I call various corporations during my day are a little more sophisticated than any ridiculous algorithm written by Microsoft and Friends can predict. So I have to hang on the phone forever to talk to a human being.

Any ideas welcome but I'm not sure this can be accomplished it's pretty sophisticated.

Thanks.
