Is there any way to mute the key beep when you enter numbers on the 8830 to place a phone call?

Even if you set key tone to off at Options, Screen/Keyboard, you will still have the barely audible dtmf tone from the phone dialer.

A trick is to type your phone number in a note, email or such, then dial or copy and paste to the dialer.
