Hint: you don't need to set 'signalling' for analog channels. Or just
set it explicitly to "auto". This is for Asterisk >= 1.6.0 . Simply
reduces the complication a bit...

Try running:

  asterisk -r

and in that prompt:

  module unload chan_dadhi.so
  module   load chan_dadhi.so

and tell us the output you got.
