 * Revision 1.29  2004/09/05 22:04:56  tobiasb
 * New parameter file entry "ignoreUPD" for suppressing "Unexpected
 * discrimator (...)" messages, demanded by Günther J. Niederwimmer
 * on the suse-isdn mailing list.
 *
 * Revision 1.28  2004/01/28 14:27:46  tobiasb
 * Second step in restricting fds at isdnlog restart and script starting.
 * The fd limit is now taken from getrlimit() instead of NR_OPEN.
 * Close_Fds(first) which tries to close all possible fds is generally
 * built in but the execution must be requested with "closefds=yes" in
 * the parameterfile otherwise the isdnlog behaviour remains unchanged.
 *
 * Revision 1.27  2004/01/26 15:20:08  tobiasb
 * First step to close all unnecessary open file descriptors before
 * starting a start script as reaction to a call.  The same applies to the
 * restart of isdnlog using SIGHUP.  Till now each restart increases the
 * number of used fds.
 * For now the modifications are inactive by default.  They can be enabled
 * by adding the line "DEFS += -DFD_AT_EXEC_MODE=1" to ../Makefile.in.
 * The next isdnlog (4.68) will have this enabled per default.
 * The upper limit for fd numbers is taken from NR_OPEN in <linux/limits.h>.
 * If there is a smarter way to access this limit, please let me know.
 * Another approach would be to set the close-on-exec flag on each fd
 * directly after it is opened.  This would require more extensive changes.
 * I'd like to thank Jan Bernhardt for discovering this problem.
 *
 * Revision 1.26  2003/08/26 19:46:12  tobiasb
 * isdnlog-4.66:
 *  - Added support for AVM B1 (with layer 2 d-channel trace) in point-to-
 *    point mode, where only TEI 0 is used ("Anlagenanschluss" in German).
 *    Many thanks to Klaus Heske for his testing efforts.
 *  - The source number "0" in outgoing calls is now expanded to
 *    +<country><area>0.  This may be useful for point-to-point setups,
 *    when <area> contains area code and local number without extension.
 *  - Basic support for different codesets in (E)DSS1 messages.  Except
 *    for codeset 0, unknown information elements are now silently
 *    ignored (controlled by ignore_unknown_IE in isdnlog/isdnlog.h).
 *  - Added some information elements to isdnlog/messages.c.
 *  - Increased the length of msn (local number) in struct telnum.
 *  - Fixed seperation of country and area code for long numbers
 *    in getDest, tools/dest.c.
 *  - Changed broken (with gcc 2.95.2) generation of .depend.  The old
 *    output did not consider the location of objectfiles in subdirs.
 *    Remove this file before compiling this upgraded isdnlog.
 *  - Moved DUALFIX... defines from tools/tools.h to isdnlog/isdnlog.h.
 *  - Added missing R:-Links for cellphone entries in country-de.dat.
 *  - Different entry for each city "Neustadt" in tools/zone/de/code.
 *  - Earlier changes since isdnlog-4.65:
 *     - Allow dualmode workaround 0x100 (DUALFIX_DESTNUM) to work also with
 *       CALL_PROCEEDING messages for cleaning up unanswered incoming calls.
 *
 * Revision 1.25  2001/06/08 11:55:24  kai
 * fix to compile with newer kernel headers. Maybe someone wants to fix isdnlog to recognize the number of channels at run time?
 *
 * Revision 1.24  1999/12/31 13:30:02  akool
 * isdnlog-4.00 (Millenium-Edition)

 *
 * WARNING: This is pre-ALPHA-dont-ever-use-Code!
 * 	 "tarif.dat" (aka "rate-xx.dat"): the next generation!
 *
 * You have to do the following to test this version:
 *   cp /usr/src/isdn4k-utils/isdnlog/holiday-de.dat /etc/isdn
 *   cp /usr/src/isdn4k-utils/isdnlog/rate-de.dat /usr/lib/isdn
 *   cp /usr/src/isdn4k-utils/isdnlog/samples/rate.conf.de /etc/isdn/rate.conf
 *
 * After that, add the following entries to your "/etc/isdn/isdn.conf" or
 * "/etc/isdn/callerid.conf" file:
 *
 * [ISDNLOG]
 * SPECIALNUMBERS = /usr/lib/isdn/sonderrufnummern.dat
 * HOLIDAYS       = /usr/lib/isdn/holiday-de.dat
 * RATEFILE       = /usr/lib/isdn/rate-de.dat
 * RATECONF       = /etc/isdn/rate.conf
 *
 * Please replace any "de" with your country code ("at", "ch", "nl")
