 * Revision 1.65  2007/01/05 04:23:58  tobiasb
 * Made isdnrep and isdnrate buildable under cygwin. See ChangeLog for details.
 *
 * Revision 1.64  2005/02/23 14:33:40  tobiasb
 * New feature: provider skipping.
 * Certain providers can be completely ignored (skipped) when loading the
 * rate-file.  The selection is done by Q: tags in rate.conf or by skipProv=
 * in the parameter file.  The syntax is explained in the new manual page
 * rate.conf(5).  Absurd settings for provider skipping may cause trouble.
 * The version number will change to 4.70 in a few days after an update
 * of the rate-de.dat.
 *
 * Revision 1.63  2004/09/29 21:02:02  tobiasb
 * Changed handling of multiple "calling party number" information elements.
 * The network provided number is now preferred in any case.  The other
 * number (typical set by originating user) can be ignored using the
 * ignoreCOLP or -U setting, which allows different values for COLP and CLIP
 * now.  (The old behaviour was to use the first number if ignoreCOLP was set
 * and the network provided number regardless of order otherwise.)
 *
 * Revision 1.62  2004/09/05 22:04:57  tobiasb
 * New parameter file entry "ignoreUPD" for suppressing "Unexpected
 * discrimator (...)" messages, demanded by Günther J. Niederwimmer
 * on the suse-isdn mailing list.
 *
 * Revision 1.61  2004/07/24 16:16:56  tobiasb
 * New entry `REPOPTIONS' in section [ISDNLOG] of the isdn configuration
 * file.  This will be used for commandline options defaults of isdnrep.
 *
 * Revision 1.60  2004/01/28 14:27:47  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 1.59  2003/08/26 19:46:13  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 1.58  2003/07/25 22:18:04  tobiasb
 * isdnlog-4.65:
 *  - New values for isdnlog option -2x / dual=x with enable certain
 *    workarounds for correct logging in dualmode in case of prior
 *    errors.  See `man isdnlog' and isdnlog/processor.c for details.
 *  - New isdnlog option -U2 / ignoreCOLP=2 for displaying ignored
 *    COLP information.
 *  - Improved handling of incomplete D-channel frames.
 *  - Increased length of number aliases shown immediately by isdnlog.
 *    Now 127 instead of 32 chars are possible. (Patch by Jochen Erwied.)
 *  - The zone number for an outgoing call as defined in the rate-file
 *    is written to the logfile again and used by isdnrep
 *  - Improved zone summary of isdnrep.  Now the real zone numbers as
 *    defined in the rate-file are shown.  The zone number is taken
 *    from the logfile as mentioned before or computed from the current
 *    rate-file.  Missmatches are indicated with the chars ~,+ and *,
 *    isdnrep -v ... explains the meanings.
 *  - Fixed provider summary of isdnrep. Calls should no longer be
 *    treated wrongly as done via the default (preselected) provider.
 *  - Fixed the -pmx command line option of isdnrep, where x is the xth
 *    defined [MSN].
 *  - `make install' restarts isdnlog after installing the data files.
 *  - A new version number generates new binaries.
 *  - `make clean' removes isdnlog/isdnlog/ilp.o when called with ILP=1.
 *
 * Revision 1.57  2000/09/05 08:05:03  paul
 * Now isdnlog doesn't use any more ISDN_XX defines to determine the way it works.
 * It now uses the value of "COUNTRYCODE = 999" to determine the country, and sets
 * a variable mycountrynum to that value. That is then used in the code to set the
 * way isdnlog works.
 * It works for me, please check it! No configure.in / doc changes yet until
 * it has been checked to work.
 * So finally a version of isdnlog that can be compiled and distributed
 * internationally.
 *
 * Revision 1.56  2000/08/06 13:06:53  akool
 * isdnlog-4.38
 *  - isdnlog now uses ioctl(IIOCNETGPN) to associate phone numbers, interfaces
 *    and slots in "/dev/isdninfo".
 *    This requires a Linux-Kernel 2.2.12 or better.
 *    Support for older Kernel's are implemented.
 *    If IIOCNETGPN is available, the entries "INTERFACE = xxx" in
 *    "/etc/isdn/isdn.conf" are obsolete.
 *  - added 01013:Tele2 totally Freecall on 12. and 13. August 2000
 *  - resolved *any* warning's from "rate-de.dat" (once more ...)
 *  - Patch from oliver@escape.de (Oliver Wellnitz) against
 *  	 "Ziffernwahl verschluckt Nummern"
 *
 *    **Please "make clean" before using this version of isdnlog!!**
 *
 * Revision 1.55  2000/06/29 17:38:28  akool
 *  - Ported "imontty", "isdnctrl", "isdnlog", "xmonisdn" and "hisaxctrl" to
