I had the Motorola Droid, with the slide out keyboard, and could hear every call coming in and every text/email alert. Now I have the Droid X and cannot hear it unless it is very quiet. I just got a leather case for my belt so I am certain I will never hear the phone ring if the phone is in the case. Even with the phone face down on the console of my car with the stereo on at low volumes I cannot hear the phone ring. One lady posted she cannot hear the phone if its in her purse....good point and proof the volume is not high enough.
I spent over an hour on the phone with Verizon. I urge everyone to contact Verizon on a phone other than the Droid X so they can walk you through the usual steps that will not correct the problem.
Luckily, the Verizon representative I worked with contacted Motorola with me on the line. After their usual steps the Motorola representative obtained the Motorola Droid and the Droid X and compared the volume and everyone agreed there is a difference.
Now contact Verizon and Motorola so we can keep our X's. If this cannot be fixed I will be forced to get another phone.
