Install the kernel source for your running kernel. Then you can do the
following
cd /usr/src/[kernel-version]
cp /boot/config-[kernel-version] .config
make clean
make oldconfig
make dep
cd /usr/src
ln -s [kernel-version] linux
ln -s [kernel-version] linux-2.4

Now your kernel source is ready for compiling zaptel.
cd /usr/local/src/zaptel-1.0.0
make clean install
cd ../asterisk-1.0.0
make clean install

Everything should now be built

Load the module for the TDM22B:
modprobe wcfxs
ztcfg -vv
asterisk -vvvc
