When I set the ringer setting on my 4400 to High and Vibrate, all it does is vibrate. It did this on my last one, I got a new one, not for that reason, but I noticed that it still does not ring and vibrate, it only vibrates. Just wondering if any of you know what is going on or have a situation that you can tell me about. I will probably bring it in tomorrow to the store to find out what is up. Thanks!!!
