Line disconnected during a call? Alert will go off!

Was looking for an app to let me know when someone hung up the phone so that I know that I am disconnected because here a lot of times the network drops and I continued to talk for another minute for nothing, and yes it exists! Check out this so funny video!

It's the funniest app video I've ever seen by far! So basically anytime your call has been dropped or disconnected, a voice notification lets you know.
