A "device" corresponds to a B-chanel in capi.conf. See the capi.conf
form chan_capi source tarball - it uses devices=2 for BRI lines, and
devices=30 for PRI lines.

So the C4 appears to chan_capi as 4 controllers with 2 devices each.

You need to set up a separate interface section for each "controller"
that is actually in use, and just skip the rest:

[interfaces]

; The first controller
msn=...
...
controller=1
devices=2

; The second controller
msn=...
...
controller=2
devices=2

"capi info" reports all the CAPI devices that exist in the system, but
that doesn't mean it is really using them all.

If you start Asterisk in verbose mode "asterisk -vc" , you should see
a warning like this for every unused CAPI controller:

Oct 28 15:41:04 WARNING[1076791936]: chan_capi.c:2786 load_module: Unused contr2

This is what I get on a system with a C2 card where only one of the
two controllers is configured in capi.conf.
