Hey Michael,

thanks. In the moment there is another problem.

Since yesterday I wasn't able to load the module zaphfc.

> modprobe zaphfc
> FATAL: Error inserting zaphfc
> (/lib/modules/3.0.22/dahdi/zaphfc/zaphfc.ko): Unknown symbol in module, or
> unknown parameter (see dmesg)
>

Now I'm installing Asterisk a second time and hope that it works. Then I
will try your advice again and give you a answer how it works.

Wish you a nice day.

Regards
Ellen
