Here are some examples of some actions that can be taken and the context in which they appear: On a call Transfer Hold Park Idle (no call) Do not disturb Retrieve Ringing (incoming call) Answer Reject When you are on a call, your soft buttons may include Hold, Transfer, Park, etc. While you are idle, they may include turning on DND, and Retrieving a parked call. While the phone is ringing, it may include answering the phone (on speakerphone) or Rejecting the call to Voicemail. Many manufacturers allow soft keys to be customized to a small degree, removing or adding options.
