If you where on google and saw the same questions, you should have been
able to follow the rabbit further down the hole by playing with the
links at the bottom of the pages google provided. You would have seen
use rant regularly that you need to work just a tad harder to find the
answer. It is there. It is consistently the same problem. 

You lack disconnect supervision. The only way to know the line has been
hungup is to use progress detection and possibly tweak for your
location.
