  • Additional services and events for call and device control.
  • Enhancement to existing services and events.
  • Organisation of services and events to reflect a grouping based on function (call control, device control, etc.)
  • Use of a consistent template for services and events that includes initial/final Connection State, connection state transitions, event monitoring sequences, etc.
