ISDN with a passive card under Debian Tutorial


This howto is only for Debian Sarge and 2.4.x kernels!

The AVM CAPI driver
Capisuite

My system

  • CPU : 1,2 GHz Athlon
  • RAM : 768 MB SDRAM
  • AVM Fritzcard PCI
  • OS : Debian Sarge (stable)
  • Kernel : 2.4.27

Requirements

  • 2.4.x kernel
  • AVM Fritzcard PCI
  • kernel sources and headers

Preparations

First, we install the packages isdnactivecards (even if we use a passive card) and pppdcapiplugin via

apt-get install isdnactivecards pppdcapiplugin

Afterwards we check whether the kernel sources and headers are installed and unpacked in /usr/src/:

gate:/usr/src # ls -l
total 12k
drwxr-xr-x   5 root   src     4.0k Jan 22 17:10 kernel-headers-2.4.27-2
drwxr-xr-x   5 root   src     4.0k Jan 22 17:12 kernel-headers-2.4.27-2-k7
drwxr-xr-x  15 root  root     4.0k Jan 22 17:52 kernel-source-2.4.27
lrwxrwxrwx   1 root   src       20 Jan 22 17:12 linux -> kernel-source-2.4.27
gate:/usr/src #

If this is the case we can download the AVM capi driver (fcpci-suse8.1-03.10.02.tar.gz) from ftp://ftp.avm.de/ and unpacking in /usr/local/src/:

cd /usr/local/src
gzip -d fcpci-suse8.1-03.10.02.tar.gz
tar -xvf fcpci-suse8.1-03.10.02.tar

All driver versions newer than 8.1 won't compile under Debian!

The AVM capi driver

Now we change into the driver directory:

cd /usr/local/src/fritz

Because we want to build our own driver instead of using the pre-compiled version by AVM we must change some things in the file src.drv/makefile of the Fritz package:

KRNLINCL        = /usr/src/kernel-headers-`uname -r`/include
#KRNLINCL        = /lib/modules/`uname -r`/build/include
#KRNLINCL        = /usr/src/linux/include

Then we have to change

DEFINES         = -DMODULE -D__KERNEL__ -DNDEBUG \
                  -D__$(CARD)__ -DTARGET=\"$(CARD)\"
CCFLAGS         = -c $(DEFINES) -O2 -Wall -I $(KRNLINCL)

into

DEFINES         = -DMODULE -DMODVERSIONS -D__KERNEL__ -DNDEBUG \
                  -D__$(CARD)__ -DTARGET=\"$(CARD)\"
CCFLAGS         = -c $(DEFINES) -march=i386 -O2 -Wall -I $(KRNLINCL) \
                -include $(KRNLINCL)/linux/modversions.h

Finally we change lines 29 and 30 in src.drv/tools.c from

#else
#include <linux/malloc.h>

to

/* #else
#include <linux/malloc.h> */

Now we can build and install the driver:

cd /usr/local/src/fritz
make clean
make
make install

The following modules must be added to /etc/modules:

capi
capifs
capidrv
capiutil
fcpci

and are loaded via /etc/init.d/modutils restart. A possibly already loaded Hisax module must be unloaded first, of course. Capi should work this way. We can check this by calling capiinfo. If it works its output should look similar to this:

gate:/root # capiinfo

Capisuite

Install Capisuite via

apt-get install capisuite

To enable it, we have to change in the file /etc/default/capisuite fom "n" to "y":

run_capisuite_daemon=y

Now we start Capisuite calling /etc/init.d/capisuite start and verify that Capisuite is running properly via ps ax |grep capisuite. The configuration of Capisuite is explained using an example config:

/etc/capisuite/answering_machine.conf:

[GLOBAL]
audio_dir="/usr/share/capisuite/"
voice_user_dir="/var/spool/capisuite/users/"
user_audio_files="1"
record_silence_timeout="5"
voice_email_from="capisuite daemon "

[alex]
voice_numbers="123456"			# number to answer (without prefix)
voice_action="MailAndSave"		# MailAndSave / Mail / Save
voice_delay="30"
record_length="60"
voice_email="alex"			# address to mail to 
pin="12"

The file /etc/capisuite/capisuite.conf can stay mostly unganged.

/etc/capisuite/fax.conf

[GLOBAL]
spool_dir="/var/spool/capisuite/"
fax_user_dir="/var/spool/capisuite/users/"
send_tries="10"
send_delays="60,60,60,300,300,3600,3600,18000,36000"
send_controller="1"
outgoing_MSN="123457" 			# number to send from
outgoing_timeout="60"
dial_prefix=""
fax_email_from="capisuite daemon "

[alex]
fax_numbers="123457"			# number to answer (without prefix)
fax_stationID="+49 911 123457"		# number (with prefix)
fax_headline="send by alex"		# headline
fax_email="alex"			# address to mail to 
fax_action="MailAndSave"		# MailAndSave / Mail / Save

All changes take effect without requiring a restart. Further information about Capisuite can be found in the manpages or in the HOWTOs on the net.
