I think the idea of SWAFO is a good one. However he is using examples of specific procedures. At the airline I used to work for we did not
use the 4 time ring. Three times was emergency call for us. So this is very airline specific. I think you should avoid implement features
which are airline specific...

From what I hear now, nearly every airline has adopted the 4 ring system.
