I would like to suggest a change to the way the current Do Not Disturb feature is implemented at the badge.  Today, when one user calls another user that's in DND the caller is prompted to leave a message.  In addition to this functionality I would like to see the additional option of "Urgently Call" the user as a voice prompt.  Although all of our users are trained on the "Urgently Call" command it's used so infrequently that most users forget it.  There are times when our doctors have put themselves in DND yet the situation warrants an Urgent Call.  In practice, nurses choose not to leave a message because the situation is urgent and the connection is never made.
