Technical Report TR/80
Migrating to CSTA Phase III

(June 2000)

The purpose of this Technical Report is to aid the transition to CSTA Phase III by those who are already familiar with Phases I and II.

Phase III of CSTA extends the previous Phase II Standard in major theme directions as well as numerous details. Major areas of advancement include:

  • 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.
