This happened to me as well during my first week of ownership. Battery reboot did the trick.

The issue I'm having is with the numeric keypad. What happens is I'll use the numeric keypad to dial out. While in the call if I wish to use the numeric keypad to dial an extension i'm only given the following keys; 0,1,5,* and voice mail. Any ideas?
