Why can't mobile phone operators agree on a standard short warbling sound, or even better if it is possible an inaudible control signal, to instruct one's mobile that the current call is to a menu system and will require the caller to type input, generally numbers?
That way the phone would know to maximise the number keypad on the display without the user having to press a button to do this. Drives me potty having to do it each time, and more than once I've accidently disconnected the call!
