You did not provide system.conf. Do you have something like this (may
have errors, I did not check):

loadzone = uk
defaultzone = uk
span => 1,1,0,ccs,ami,te,term
bchan = 1,2
hardhdlc = 3

span => 2,2,0,ccs,ami,te,term
bchan = 4,5
hardhdlc = 6

span => 3,3,0,ccs,ami,te,term
bchan = 7,8
hardhdlc = 9

span => 4,4,0,ccs,ami,te,term
bchan = 10,11
hardhdlc = 12


Then as root:
modprobe wctdm23xxp

And as root:
dahdi_cfg -vvv

And check if all is well (green leds, happy messages in
/var/log/messages, etc.).


Then in chan_dahdi.conf use something like:

;BRI Module
group = 1
signalling = bri_cpe
context = incoming
channel => 1,2,4,5,7,8,10,11

Your chan_dahdi.conf has "group" and "context" multiple times and that
does not seem right (admittedly it's been ages since I setup a Digium card).

Hope this helps. If not follow the installation manual step for step or
call Digium support.
