There needs to be an option to turn ON/ OFF the DTMF tone (keypad sounds) when using the keypad on the desktop app and cell phone app. It currently is set to play the DTMF tone automatically and there is no way to turn it off without disabling the sounds on the device that you're using. This is highly distracting because the keypad sounds when you press a button are not in sync with the actual buttons being pressed if you are dialing quickly. The sound delay is especially distracting when entering memorized phone passcodes and phone numbers because you're halfway into the entry when you get distracted by arrhythmic beeping and have to start again. Please make this feature an option.
