For starters, there's the example / reference chan_dahdi.conf:


Replace 'trunk' with 'tags/<version>' for the a specific version.

Minor nit: generally there's no need to quote FreePBX and URLs. I
believe that for URLs it actually does harm as it increases the chance
of people accidentally copying the quote marks as part of the URL.

Do you have FreePBX installed or not?

You can consider Asterisk to be a PBX toolkit and FreePBX to be a PBX
created with that toolkit. FreePBX has its own versions for
configuration files. Specifically the version it has for chan_dahdi.conf
does not look like the one you have.

That's just wrong.

The section name "[global]" is not special in chan_dahdi.conf. It will
be parsed as a specific channel section (parsed after [channels])
The section names [general] (that you happen to use) and [globals] will
not be parsed: they are reserved for future use.

Ignoring the section [trunkgroups], which you should not care about in
your setup, your configuration should look either as:

; global settings

; Per-channel-settings
channel => <chan-spec1>

; Per-channel-settings
channel => <chan-spec2>

; global settings

dahdichan => <chan-spec1>
; Per-channel-settings

dahdichan => <chan-spec2>
; Per-channel-settings


; global settings

#include dahdi-channels.conf

and generate /etc/asterisk/dahdi-channels.conf (as well as
/etc/dahdi/system.conf) by running dahdi_genconf. That should get you

Note that Asterisk will barf if it encounters an #include of a file that
does not exist.
