============

I have not installed any dahdi hardware.

Thanks in advance for any help.

The dahdi modules must be loaded before you start Asterisk. If the init.d script says OK, it suggests that it wasn’t run duing startup.

Thanks David, appreciate your help. it’s working…

I stopped the dahdi

[root@ws1 asterisk]# /etc/init.d/dahdi stop
Unloading DAHDI hardware modules: done

Then Stopped asterisk

ws1CLI> core stop now
ws1CLI>
Disconnected from Asterisk server
Asterisk ended with exit status 0
Asterisk shutdown normally.

Then start dahdi again.

[root@ws1 asterisk]# /etc/init.d/dahdi start
Loading DAHDI hardware modules:
wct4xxp: [ OK ]
wcte12xp: [ OK ]
wct1xxp: [ OK ]

wcfxo: [ OK ]
wctdm: [ OK ]
wcb4xxp: [ OK ]
wctc4xxp: [ OK ]
xpp_usb: [ OK ]

Running dahdi_cfg: [ OK ]

Then start the asterisk

root@ws1 asterisk]# safe_asterisk &
[1] 13446
[root@ws1 asterisk]#
[1]+ Done safe_asterisk

And after restarting it’s working fine. i don’t see the error again
