First of all there is a Mandrake 10.0 CE ISDN problem

Error scenario: ISDN support in drakconnect is broken.

Why: Drakconnect did not fill in some fields in one configuration file.
Solution: Apply the patch from the Mandrake errata site.

as root by executing:

# cd /usr/lib/libDrakX
# patch -p0 < /path/to/downloaded/drakxisdn.patch
