For some reason, when anyone calls my regular AT&T cell # and leaves me a message, it goes right to google voice and doesn't show up in my regular iphone voicemail. This also happens if someone doesn't leave a message ... I get an alert from Google Voice saying that I've missed a call. I have no idea as to how or why this just started happening. Any Google Voice experts out there know how to get my regular number back to AT&T voicemail?? Actually, when I call my ATT number from another phone and I let it go to voicemail, it's the google voice message I hear instead of the default AAT message ... very strange!
