There was a thread that I can't locate that spoke about a "one button" technique to instantly reject/send an out of the blue call to voicemail - not just turn off the ringer, but divert it straight to voicemail. I don't need to customize settings, just be able to reject a call in one motion - the way you could with a 'feature phone' (aka dumb phone). Is it the power button, the volume up or the volume down? Thanks!
