Asterisk config example

Someone asked for a copy, so here’s an edited copy of my Asterisk extensions.conf file. I changed most of the email addresses to user@example.com, and replaced parts of specific phone numbers with ‘9999’, but other then that, it’s essentially the same. There’s some legacy cruft in here, and parts of it are overly complex. It implements a few features that you don’t strictly need in most setups. particularly the 10-digit dialing bit that makes ‘1’ for long distance optional. Here it is, warts and all:

; The next block of macros handle outgoing calls.  This is more complex
; then you'd expect for a couple reasons.  First, I'm using two different
; outgoing mechanisms--NuFone and my POTS line, but I'd like either one
; to be able to work as a fallback if the other fails.
;
; Next, I want to be able to handle 7- and 10-digit dialing without
; having to remember which area codes and prefixes require a '1' first.
; I'm in the Seattle area, and part of 425 is free, along with 95% of
; 206.  With POTS, I must dial a '1' iff it is a toll call.  With
; NuFone I must always dial a 1.
