We have been updating the software on DT570 to R3C to fix the issue with "MUTE" not being displayed when muted which is great. The only downside to this is that as soon as you press the keypad to send tones when in a call you get all the digits displayed in duplicate - once in the top line of the display and once at the bottom. Not really an issue but annoying if you e.g. enter a passcode and # to join a conference call because you have to press the clear/mute key several times to clear the top row of digits off the display before you can see "MUTE". Does anyone else have this problem?
