Query: Thumbs Down (Low Headset Volume, No Mute,Other Shortcomings)

I really wanted to like this phone, but here are the problems:1. When a headset is plugged in, the volume (for listening) is too low and can't be turned up sufficiently. (This is not a problem with the headset.)2. No mute button. Terrible if you use the phone for work/meetings.3. Limited speed dial. I like to program access codes (like mailbox number and password), since I use my phone for work purposes. I can't do that with this phone.4. The buttons are not very responsive and there is a delay until you hear a "beep" indicating that you pressed a button. Sounds petty but the result is that, when dialing, you often miss a number but don't realize it until it's too late. Then you have to start over.5. The size and shape of the phone are not conducive to holding it between your head/ear and shoulder.
