Updated Asterisk config files

I’ve had several people ask me for a more recent version of my Asterisk configuration files, and it’s been about a year since I last posted them, so here they are.

extensions.conf

Here’s extensions.conf. I’ve lightly redacted a few phone numbers and deleted a few really obvious bits of cruft, but this is essentially what my Asterisk server is running. There’s at least a year’s worth of cruft lurking in here, but it’s a real, live example:

[general]

  writeprotect=no

; This fixes up incoming CallerID.  NuFone doesn't transmit CID name
; info on incoming toll-free calls.  So, we cache the name when we see

Comments

  1. n/a about 3 hours later:

    Did you redact all your secrets? One of your NuFone ones looks real…

  2. n/a about 3 hours later:

    BTW - cool comments system. The only problem is that if you forget your name and submit, you lose your comment.

  3. n/a about 3 hours later:

    also, I think < or > in your subject (I had “<html>” in mine) makes for a nifty exception. :)

  4. Scott Laird about 2 hours later:

    Thanks, fixed.

  5. Scott Laird about 2 hours later:

    Well, the comment system is kinda new, and apparently there’s still a bug or two lurking in there. I have a couple minor fixes lurking in my dev system that I haven’t pushed out here yet; I’ll see if I can fix the two that you’ve pointed out and then push them all into production.

    You’re using Mozilla on Linux, right?

  6. n/a about 1 hour later:

    I was using the Mozilla control hosted via the Liferea feed reader - should be effectively the same as a browser.

    BTW - very cool comment system. :)

  7. Scott Laird 27 minutes later:

    Weird. I’m going to have to dig through the logs to see how you got the <html> bit. Fortunately, there’s a workaround in Rails 0.13–it’s easy to catch HTTP errors in AJAX stuff (which is where the <html> comes from) and abort, rather then piping the error message into the comment title field.

  8. yeah, my name about 1 year later:

    nice
