  Help prevent ringing queue members from being rung when ringinuse set to no.
  
  Queue member status would not always get updated properly when the member
  was called, thus resulting in the member getting multiple calls. With this
  change, we update the member's status at the time of calling, and we also
  check to make sure the member is still available to take the call before
  placing an outbound call.
