IPhone 5 :: How To Disable Handsfree Button From Turning Music On

Pressing a handsfree button once in idle/stand-by mode starts playing music. Can that be disabled?Â

I'm heavy voice and data user on my iPhone 5 however I rarely listen to music. My handsfree is plugged-in almost all the time (for convenience as I strongly prefer to use HF for voice calls).Â

Any time I accidentally press the HF button (and it happens a lot, e.g. laying the phone down on the table accidentally pressing the button by the phone itself) the bloody device starts playing music (or whatever media is stored in). This is very annoying: if nothing else it further drains the battery that anyhow barely makes it through the day (sometimes half day - I really am heavy user). But most important: when listening to anything it is usually an audio book. When the "automated" "audio-on" feature is activated it usually goes unnoticed until some time hence the story moves on without me listening - and going back looking for the spot to continue playing from is very very frustrating activity particularly since it is repeated practically every time I sit down to listen to it.Â

Going through different forums I found some solutions which however require a jail-brake - something I want to avoid if possible,Â

The best solution would allow to define a custom action ("null action" in this particular case) based on the status: I like to use the HF button during the call or even for skipping or reversing songs when eventually really deliberately listening to music (very seldom) hence only "idle / stand-by" action assigned to the HF button would be null - the rest should stay intact.Â
