p 176 has exten => 1NXXNXXXXXXX,1,Dial(SIP/${EXTEN}@myprovider)

how is "exten" distinct from "EXTEN"? What is this line of code doing?


says that EXTEN is the current extension.

In ruby, you this:

H = Hash["a" => 100, "b" => 200]

The => is a mapping, or at least that's my understanding.  What does it 
mean in Asterisk?  I didn't
fully appreciate that Asterisk is, apparently, its own language.
