• Does this file exist? If not, remove this line. If not, what does is its contents?

  Hint: Just use ‘signalling = auto’ and avoid the confusion in chan_dahdi.conf .

  However, this is not the source of your problem.

  The channels were created (at the kernel level). Kernel level signalling was given to them by dahdi_cfg. However they are not in use by chan_dahdi.

  Maybe dahdi-channels.conf doesn’t exist and this causes problems?

  Anyway, in the asterisk command-line run:

  module unload chan_dahdi.so
  module load chan_dahdi.so

  And see what errors you get.
