Motorola XPRT :: Phone Button Doesn't Work?

Two weeks into using my new XPRT and now the green phone button does nothing, well almost nothing. After a power down and battery remove-replace, the first time I push the phone button the screen blinks, then nothing. Each push thereafter does nothing.If I use the phone dialer app it's the same thing. To make a call I have to either use my Voice Mail which works fine, and use the redial function from voice mail, or use Contacts to make a call. If I want to call a number not in a VM or in my contacts, it can't be done.Android 2.2.2
