Dahdi / Sangoma W400 installation

Hello,

I wanted to install my Sangoma W400 module.

It seemed that the installation was OK, but I can’t start the Dahdi module.

Some strange thins I see:

module load chan_dahdi.so
Unable to load module chan_dahdi.so
Command ‘module load chan_dahdi.so’ failed.

Or…
dahdi show channels
No such command ‘dahdi show channels’ (type ‘core show help dahdi show’ for other possible commands)

Does somebody has an idea ?

Thanks
