Ah! Lightbulb Flash! That was a very good way to put it!

So we play and do whatever intro stuff we want. Now why is Dial on 
priority 1 and not 4? OK, I see it has extension one on it, that's 
why. So I can group the handling/steps for each extension and list 
what to do with them in sequence. If they deal with something not 
pressed it will be skipped.

Catchink! Another lightbulb! OK, time to implement my newfound 
wealth! Thanks a lot Stephen! You really should spend a few min and 
vrite down a few of these concepts for implementation into the new 
howto/doc version 2! You have cut out a huge chunk of confusion!
