I have the same problem on my iPhone 4 iOS 5.1.1 and updating to iOS 6 did not fix it. I even tried a restor as new device and still have the same problem. Now I think it is carrier specific. I have contacted customer support 2 days ago and they said they will look into it, still have not heard from them though.
Will update if I learn something new
