• Alert every minutes with tone.
• Auto Redial.
  • Automatic call again when line errors.
  • When the first wire on the other side does not prompt.
  • When busy.
  • Customize the number of call again, or call to the line where the other party prompt.
• Limited time conversation
• Automatically turn on backlight :
  • When may have connection (Connected)
  • When traffic interruption (Call fail)
  • When the call ends (Disconnect)
  • When a call waiting. (Call Waiting)
  • When the call hold (Hold).
  • When mindedness call (Call Resume)

SmartCalling is free but the developer is asking for dontations if you find it useful. This application will work on any BlackBerry OS 4.2 and higher.
