In order to enable capifax support:
 * Install spandsp 6
 * Install libcapi20-3.0.5a

If you want to use the incoming notification you will have to enable
your fritzbox with: #96*5*

If you want to use the capifax plugin you will have to enable capi-over-tcp
within your fritzbox with: #96*3*

You also need to create a new printer device with the following commands:
	mkdir -p /var/spool/ffgtk/
	chown root:root /var/spool/ffgtk/
	chmod 0777 /var/spool/ffgtk/
	cp ffgtk-cups /usr/lib/cups/backend/
	chmod 0755 /usr/lib/cups/backend/ffgtk-cups
	chown root:root /usr/lib/cups/backend/ffgtk-cups
	lpadmin -p Fax -E -v ffgtk-cups:/ -m lsb/usr/cups-included/postscript.ppd
