Where are your channels?  That's why you are receiving the error
"Unable to create channel of type 'DAHDI'".

Define your channel groups in /etc/asterisk/chan_dahdi.conf

Then is should look like this:
# asterisk -rx "dahdi show channels"
   Chan Extension  Context         Language   MOH Interpret
Blocked    State
 pseudo            default                    default
       In Service
      1            from-external   en         default
       In Service
      2            from-external   en         default
       In Service
      3            from-external   en         default
       In Service
      4            from-external   en         default
       In Service
      5            from-external   en         default
       In Service
      6            from-external   en         default
       In Service
