I use blank lines to show they are definitions of different extensions.
Consider each bunch of connected lines like a subroutine. There is the
routine for the s extension, then the 1 extension, 2 extension, t and i
extensions. You can only move from one subroutine to the next either via
keypresses or some form of Goto, or other extension directives that can
act on extention and priority like an AGI script.

in asterisk issue
show application dial
This will prompt you with how dial works. Dial will jump to n+101 if
n+101 exists and the channels you specify are busy.
