Issue after upgrade 1.4 => 1.6.2


after upgrading asterisk (from 1.4 to 1.6.2) i have a little problem…
Each time i try to make a call i recive the following error: app_dial.c:1745 dial_exec_full: Unable to create channel of type ‘DAHDI’ (cause 0 - Unknown)
i have already setted up the file asterisk/chan_dahdi.conf with this parameter (the same of the old zapata.conf file):

  • switchtype=euroisdn
  • pridialplan=national
  • signalling=pri_cpe
  • signalling=fxo_ls
  • channel => 1-15,17-31

the digium card is a TE110P

any idea ?

thanks a lot


  1. What is the output of the following commands:

cat /proc/dahdi/* asterisk -rx "dahdi show channels

  1. In your post you have 2 signalling config and the last one (fxo_ls) is wrong for a TE110 card
    I think your dahdi files are not ok thus please post (both of) them: /etc/dahdi/system.conf and /etc/asterisk/chan_dahdi.conf
