When you mute the phone in the auxmenu (don't use the profile switcher from zhone!), silent.state is loaded and the silent profile is choosen.
If you plug in the headset, headset.state is loaded, an the profile switches to headset or headset_silent(they are the same, just to remember if the phone is muted or not)
during a call gsmhandset.state or gsmheadset.state is loaded
