My Iphone Declines Incoming Calls When My Phone is Locked?

My Iphone 3GS with the latest iOS 6 update keeps declining calls when its locked. My phone never rings nor does it alert me when i get a text message. It will only alert me when the phone is left unlocked.

i'm using an att-go phone sim card and i had no problems with it for almost a year but now i've been having issues for almost two months.i've tried restoring it as well… But nothing changed…

Update to ios 6.0.1
it has alot of bug fixes, that will fix the problem

There's a new feature in the ios update its called do not disturbed.go to settings and look for the do not disturb and turn it off. Its meant for when your sleeping or busy to cancel all calls.

  • My iphone power button is broken, how do I cancel incoming calls? So my power button is broken and i'm on assistive touch but the problem with assistive touch is that to get to the power button i have to press the dot then a sub menu then the lock so to cancel an incoming call i have to press six times and it's kinda annoying, so is there a shortcut where i can cancel the calls by one or two touches can i change the function of other buttons to make it cancel the call?
