Who at Digium is saying that POTS inband progress detection will definitely 
work and that they will make it work no matter what?  Nobody at Digium that I 
know would ever say anything like that, because inband progress detection is 
a fool's errand in this day and age.  

It *can* work, but it's difficult, not guaranteed and is prone to 
misdetection.  The second you *rely* on it, as it appears you are trying to 
do, that is when it will jump up and bite you on the ass.  This is one of the 
biggest reasons why anyone doing this professionally uses a PRI.
