Instructions for Getting on C*NET with FreePBX

[Hill Haven Telephone Company]

There wasn't much as far as Howto's or documentation on connecting to C*NET with FreePBX so I wrote a howto to make it easier for folks who want to get on C*NET but prefer the nice gui interface that FreePBX provides. 

Here is a link to the blog post documenting every step of the way.   I plan on writing another post about how to configure Lenny with C*NET and a bunch of other things.

Ugh...need better glasses...I see there's an attached PDF. Thanks for that!

I used the attached PDF to get started, but I'm still having some issues. Outbound calls fail due to no trunk available. I'll post when I get those worked out. I believe I will be learning a lot about Asterisk, FreePBX and how they interact (or don't) in the near future!

I think there's a typo in step 2 and step 3: "Local/$OUTNUM@cnet-out" should be "Local/$OUTNUM$@cnet-out"
($ at the beginning *and* end of OUTNUM?). It's presented both ways and I'm not sure which is correct. Also, it doesn't seem to make a difference!

Finally, trying to copy and paste the extensions_custom.conf file at the end of the PDF results in gibberish, so I have attached a text copy of it below.

Double-Ugh!

Replace the lines above with these, otherwise you won't be able to dial out. White space matters in this scripting language.
