From mISDN.org

What you need

• Debian Distribution
• mISDN V2
• mISDNuser V2

Download and install mISDN V2

git-clone git://git.misdn.org/git/mISDN.git/
git-clone git://git.misdn.org/git/mISDNuser.git/
cd mISDN
./configure

• Copy mISDN.cfg.default to standalone/mISDN.cfg and edit it for you needs

It contain a list with all CONFIG_MISDN* defines, one per line If you want to unset one feature, please set a '#' before it (do not remove the line!)

cp mISDN.cfg.default standalone/mISDN.cfg
make modules
make modules-install

cd ../mISDNuser

for kernel Version 2.6.32.2 use --with-AF_ISDN=34 (e.g. dmesg | grep family)

./configure --with-AF_ISDN=34 
make
make install

That´s it. You should have a working mISDN V2 and mISDNuser V2.

Now you should load the modules. There are no more module options for the hardware drivers.
That´s why the mISDN script won´t work at the moment. You have to load the modules by hand.
Do the following:

modprobe mISDN_core
modprobe <driver>
modprobe mISDN_dsp
modprobe mISDN_dsp_oslec

Replace <driver> with hfcpci,hfcmulti,... depending on your hardware

in /var/log/syslog you should see something like this:
