       isdnlog - isdn log system (and more)


       Isdnlog  gets  information  from  your  isdn  card,  decodes  this information, and can do
       anything with it, such as logging, starting programs, and more. All options to isdnlog can
       be given as command line flags, or you can specify a file with options (recommended).


       Isdnlog  only  works with the HiSax isdn driver. Other cards with their own driver are not
       supported. Additionally you need to enable  d-channel  logging  (you  can  use  "hisaxctrl
       <DriverId>  1  4"  to  do that, e.g. "hisaxctrl line0 1 4"). Isdnlog can only log outgoing
       calls that originate from your isdn card, and incoming calls.  To  get  information  about
       outgoing  calls  from  other  isdn devices (e.g. telephones), you need a second Teles isdn
       card, with crossed lines. Such a card  is  not  usable  for  communicating,  but  can  log
       outgoing calls from any device (see dual option below).


       -V     show version information and exit.

       -fFILE read  options  from  the  config file FILE.  This file is also called the parameter
              file of isdnlog.  The first line should be "[options]". You may use blank lines and
              comments  (starting  with  a  #).   All  config  files  for isdnlog have the format
              described in isdn.conf(5).  Debug options must be given on the command  line,  they
              cannot be stored in a file.

              isdnlog  will  read  from  this  device  and  from  /dev/isdninfo.  You should give
              /dev/isdnctrl0 for the first isdn card (or /dev/isdnctrl2 for the second).

              Isdnlog has a replay mode for debugging, where you can simulate  previous  recorded
              events. In that case use "-" instead of a device.

       -Ax  amt="value"
              Set  digits  necessary  to get an outside line, when connected through a PABX.  You
              can give several codes padded with a ":" (e.g. -A0:80:81:82).

              (There is no commandline option for this.)  Overwrite area code from isdn.conf.   A
              machine  connected  to  subscriber lines with different area codes and thus several
              isdnlogs running requires this non global setting.

       -Bvbn     vbn="value"
              Set the provider preselection to the given value. More prefixes may be separated by
              a ":".
              Values are e.g. "010" for DE, "10" for AT, "16:17" for NL, "9" for FR.

       -Rprefix  preselected="value"
              Set  the preselected (i.e the provider choosen, if no prefix is dialed) provider to
              value. Value should be without vbn.

              (There is no commandline option for this.)  Ignore certain providers from the rate-
              file.  The format of skiplist is the same as for Q: tags in rate.conf and described
              in rate.conf(5).

       -0x:y     trim="value[:value]"
              Suppress leading digits. If isdnlog is connected through a PABX,  it  is  sometimes
              not  possible  to  let  isdnlog distinguish between a national and an international
              call, even with help of the -A option.
              This option requires two values separated with ":" as  an  argument.  These  values
              tell  isdnlog  how  many  leading digits to remove from incoming and outgoing calls
              respectively. If only one value is given, it is used for both incoming and outgoing
              Don't use this in combination with the -A option! This will confuse the system (and
              possibly you).

              Example: a PABX in Germany shows the number of an incoming  call  from  Hamburg  as
              "00040...".   When  calling out to Hamburg, it shows the number as "0040...".  This
              means that on incoming calls, three zeroes must be removed, and on  outgoing  calls
              two zeroes must be removed (the number must be normalized to be without any leading
              zeroes in the case of a  national  number;  international  numbers  must  have  one
              leading zero). So, in this case, the option -03:2 would be correct.

       -ix  internS0="value"
              Telefon  number  shorter  then  value are considered to be internal numbers on your

       -o   other={yes|no}
              Normally "causes" (e.g. "non-selected user  clearing")  for  other  connected  ISDN
              devices  are  not displayed, only those which are related to the connection will be
              shown. With this option the causes for the other devices are also displayed.

       -ux  ignoreRR="value"
              Ignore "housekeeping" frames.  x may be 1 (ignore RR=Receiver ready) or  2  (ignore
              EMP=Euracom Management Protokoll) frames.

       -Ux[:y]   ignoreCOLP="value[:value]"
              Ignore  COLP/CLIP frames when value is 1 or greater.  Value 0 is default, and tells
              isdnlog to not ignore COLP/CLIP frames.  With value 2 the ignored COLP/CLIP  number
              is displayed.
              The  first value applies to COLP the second to CLIP. If only one value is given, it
              applies to COLP and CLIP.
              Sometimes the COLP number is a number in a different areacode to  the  number  that
              was dialled, and then the cost calculation would be wrong.

              (There is no commandline option for this.)  A PABX may cause numerous messages like
              "Unexpected discriminator 0x47 -- ignored!" resulting from  protocol  discriminator
              values  in  layer  3  not  known to isdnlog.  Set ignoreUPD to yes to suppress this

       -2x  dual="value"
              Enable dual mode. You need this if you  have  a  second  isdn  card  attached  with
              crossed  lines  so  it  can  listen  to what other isdn devices like telephones are
              doing. With x=2 you can increase the debug output -  every  single  digit  will  be

              Some  setups  may  require workarounds for reliable logging.  These workarounds are
              enabled by addition of the following numbers to the dual value.  They are  intended
              for  the  dualmode  but may also be useful without.  In this case, specify only the
              sum of the following numbers without 1 or 2 for the dual mode.

              0x100  Enable this when the destination number of an  outgoing  call  contains  the
                     number  of  the  previous  call,  e.g.  calling 222 after calling 111 before
                     results in 111222 for the second call.

                     This may also help in situations where an unanswered  incoming  call  causes
                     incorrect logging of the following outgoing call.

              0x200  Enable  this  when  outgoing  calls  are logged without a source number (own

              0x400  Enable this  when  unanswered  incoming  calls  are  logged  multiple  times
                     (revealed by isdnrep -E).

       -1     A HFC-based card is used for echo mode. Enable echo mode for the HFC card with
              hisaxctrl id 10 1
              hisaxctrl id 12 1


       -r     Replay  a  debug file (e.g. /tmp/isdnctrl0) to find bugs. With this flag you should
              give a filename with the debug information instead of a device.  It will also  work
              with files not created by isdnlog (e.g.  "cat /dev/isdnctrl0").

       -n   newline={yes|no}
              Display throughput messages on the same line (only useful with logging to stderr or
              a console device).

       -WX  width="value"
              Limit all messages to X characters per line.

       -vX  log=X
              Isdnlog can copy all information to /tmp/DEVICE (e.g. /tmp/isdnctrl0 if you started
              isdnlog  with  /dev/isdnctrl0).  Choose  what debugging you want from the following
              list, add the corresponding numbers together and use that for X:

              1      copy all "HEX:" lines from the hisax isdn device driver.
              2      copy /dev/isdnctrl output (or whatever device you specified).
              4      copy /dev/isdninfo output
              8      copy transfer values ("ibyte","obyte").

              Isdnlog will close and reopen this file after a "kill -HUP".

       -s   flush={yes|no}
              Isdnlog will flush the debug file  /tmp/DEVICE  (e.g.  /tmp/isdnctrl0)  after  each
              write access.

       -P   pipe={yes|no}
              Copy the debug information to stdout. This way you can run isdnlog as the source of
              a pipe like "isdnlog -P /dev/isdnctrl0 |prog ... ".

       -D   daemon={yes|no}
              Start isdnlog as daemon: it will fork into the background, and use  syslog  as  the
              default logging method (if you did not specify -m).

       -T     Trace mode: isdnlog will wait for a key after processing a line from /dev/isdnctrl0
              (or whatever device you specified).

       -K     Print for every pressed key the thruput. Can not used together with option -d.

       -b     If you are using a bilingual network terminator (NT), you must give this  flag,  or
              isdnlog will show the own MSN's incorrectly.


       You  can  define  aliases for telephone numbers (see callerid.conf(5) and isdn.conf(5) for
       more information). Isdnlog will compare all numbers to the list of  aliases,  and  when  a
       match is found, the alias is displayed instead of the number.


       Isdnlog  can  log  information via syslog, to stdout, and send information to x11 clients.
       Calculate a code from these numbers by adding them, and activate logging with  -s,  -m  or
       -x.  You  can  use normal numbers or hex numbers. Default is stderr mode -m, unless daemon
       mode is enabled; then it's syslog mode -l.

       0x1    Errors

       0x2    Warnings

       0x4    Notice

       0x8    Log messages to  /tmp/DEVICE  (e.g.  /tmp/isdnctrl0  if  isdnlog  is  started  with

       0x10   Show telephone numbers immediately.

       0x20   Show  charge  int  and  telephone  costs  with every charge signal (in Germany, and
              perhaps other countries, you have to pay to get these signals).

       0x40   Show connect messages.

       0x80   Show hang up messages.

       0x100  Show cause message on hang up.

       0x200  Show time messages.

       0x400  Show throughput in bytes (every -wX seconds).

       0x800  Show state of B-channels (use with -M monitor).

       0x1000 Show service indicator.
              You should log at least 0x7 (errors, warnings, notice) messages.

       0x2000 Log estimated time till next charge signal.

       0x4000 Show chargemax.

       0x8000 Enable core file on SIGSEGV.

       0x10000 ... 0x800000, show more diagnostic and debug messages.

       -mX  stdout="value"
              Log to stderr.

       -OX  outfile="path"
              Log to file X instead of stderr. Isdnlog will close this  device  when  it  gets  a
              signal -SIGHUP (-1). Only valid with -m option.
              If  the  name  starts  with  a "+", new data will be appended to the existing file.
              Default behaviour is to truncate the file when isdnlog opens it.

       -C X      console="path"
              Log to console X instead of stderr. You can use -O and -C together, so that isdnlog
              copies  output  to  both.  Specify  a  full pathname.  Beware: you must put a space
              between -C and X !

       -M   monitor={yes|no}
              With this flag, isdnlog will  generate  output  for  monitor  programs  like  imon,
              imontty or isdnmon. You must also give -m with 0x800 enabled.

       -lX  syslog="value"
              Log  to  syslog. X is the log code. You can log to syslog and to stdout at the same

       -xX  xisdn="value"
              Pass information to x11 client. X is the log code. You can pass information to  x11
              clients and log to syslog and/or stdout at the same time.

       -pPORT port="value"
              Pass information to x11 client on this PORT.

       -cX  calls="value"
              Only  with  -xX : save the last X calls and pass this information to an x11 client.
              Default value is 100.

       -LX  xlog="value"
              Only with -xX : save the last X messages  and  pass  this  information  to  an  x11
              client. Default value is 500.

       -wX  thruput="value"
              If  you enabled throughput logging (0x400), isdnlog will log the throughput every X

       -Ix:y     ciinterval="value[:value]"
              Interval for printing of charge messages (0x20).
              The first value is the interval for the calculated CI, the second value for the  EH
              (AOC-D) messages. If only one value is given, both intervals are set to this value.


       -dx  abclcr="value"
              Value is a bitmap:
              0 ... off
              1 ... calls to different area / country
              2 ... local calls too
              4 ... special numbers e.g. ISP
              This needs a kernel patch to work. If the kernel patch is not found a simulation is
              Note: depending on your telefon provider local area calls may or may not be  routed
              to  alternate  providers.   For changing the ISP a script is called. s. next option

              (There is  no  commandline  option  for  this.)   This  script  is  called  with  3
              parameters,  the new provider number (from rate-CC.dat), the number, which would be
              dialed, and the servicename.  The script should adjust routing, name resolution and
              so on to connect to the ISP.  If the script returns non zero, LCR will not be done.


       -tX  time={0|1|2}
              Isdnlog  will  set  your  local  system  time  to the time transmitted by your isdn
              service provider: -t1 = once, -t2 = every time.


       -hX  hangup="value"
              The isdn kernel system has a chargehup system, so it will hang  up  a  few  seconds
              before  the  next  charge  signal. If you don't get a charge signal from your phone
              company, isdnlog can emulate it.

              On every outgoing connection, isdnlog will calculate the charge time  from  day  of
              week, time of day and the distance zone of the connection.

              The  kernel  needs to know how long the charge time is, and how many seconds before
              the next charge signal it should hang up. You have to set the second parameter with
              X  in  the form number:number (hang up seconds before next charge signal for charge
              times greater than or equal to 20 seconds :  for  charge  times  of  less  than  20

              With  this  information,  isdnlog  will  call  "isdnctrl chargeint <device> <charge
              time>" and "isdnctrl  huptimeout  <device>  <seconds  before  charge  signal>"  (it
              actually  communicates directly with isdn, without calling isdnctrl, but this would
              have the same effect).

              You should run isdnlog with -t1 or better with -t2, so isdnlog sets the local  time
              in sync with telephone switching office.

              If  there  is  a  third  number  in  value, this is the minimum connection time for
              providers charging a basic rate per connection.
              e.g. hangup 3:5:60


       isdnlog can react on any event and start programs. This feature  is  disabled  unless  you
       activate it with:

       -S   start={yes|no}
              active "START" feature. Please read callerid.conf(5) for more information.

              (There  is  no commandline option for this.)  If set to yes, isdnlog will close all
              unnecessarily opened file descriptors before a "START" program is  executed.   This
              closing will also take place at isdnlog's restart after SIGHUP.  Default is no.


       isdnlog  will  log all connections in /var/lib/isdn/calls. isdnrep can parse this file and
       calculate costs.


       If you have more than one isdn card, you need to run one isdnlog for each card. And  every
       process  must  have  a  different  name,  so you should create a symbolic link isdnlog1 ->
       isdnlog, and start isdnlog1 for the second card.


       You cannot unload isdn kernel modules while an isdn device is in use, e.g. a PPP interface
       is  defined or isdnlog is running. Look at /var/run for a file with the
       process id of isdnlog, and kill that. After that you should be able to  unload  your  isdn
       kernel modules.


              isdnlog requires a device as a parameter to read from (e.g.  /dev/isdnctrl0 for the
              1st isdn card).

              isdnlog can copy everything it reads  to  this  file  as  debug  information  (e.g.
              /tmp/isdnctrl0 if you started isdnlog with /dev/isdnctrl0).

              isdnlog creates this file with its process id. Useful to see if isdnlog is running.

              isdnlog  creates a lock file for the device, so no other processes will access that

              isdnlog config file. Options to isdnlog can be given on the command  line,  can  be
              stored  in this file in [options] (with command line option -f/etc/isdn/isdn.conf),
              or in a different config file, but isdnlog will look  at  this  file  for  sections
              [global] [variables] [isdnlog].


       SIGHUP (-1)
              On SIGHUP isdnlog restarts, and does therefore reread it's config files.

       SIGINT (-2), SIGTERM (-15), SIGQUIT (-3)
              Isdnlog quits gracefully on receiving these termination signals.

       SIGSEGV (-11)
              If  the  log  level  contains  0x8000  (and  your ulimits permit this) isdnlog will
              generate a core file before terminating.


       I start isdnlog with "isdnlog -f/etc/isdn/isdn.conf /dev/isdnctrl0".  This file contains a
