* Revision 1.127 2003/10/29 17:41:34 tobiasb
24
* - Enhancements for isdnrep:
25
* - New option -r for recomputing the connection fees with the rates
26
* from the current (and for a different or the cheapest provider).
27
* - Revised output format of summaries at end of report.
28
* - New format parameters %j, %v, and %V.
29
* - 2 new input formats for -t option.
30
* - Fix for dualmode workaround 0x100 to ensure that incoming calls
31
* will not become outgoing calls if a CALL_PROCEEDING message with
32
* an B channel confirmation is sent by a terminal prior to CONNECT.
33
* - Fixed and enhanced t: Tag handling in pp_rate.
34
* - Fixed typo in interface description of tools/rate.c
35
* - Fixed typo in tools/isdnrate.man, found by Paul Slootman.
36
* - Minor update to sample isdn.conf files:
37
* - Default isdnrep format shows numbers with 16 chars (+ & 15 digits).
38
* - New isdnrep format (-FNIO) without display of transfered bytes.
39
* - EUR as currency in Austria, may clash with outdated rate-at.dat.
40
* The number left of the currency symbol is nowadays insignificant.
41
* - Changes checked in earlier but after step to isdnlog-4.66:
42
* - New option for isdnrate: `-rvNN' requires a vbn starting with NN.
43
* - Do not compute the zone with empty strings (areacodes) as input.
44
* - New ratefile tags r: und t: which need an enhanced pp_rate.
45
* For a tag description see rate-files(5).
46
* - Some new and a few updated international cellphone destinations.
48
* NOTE: If there any questions, problems, or problems regarding isdnlog,
49
* feel free to join the isdn4linux mailinglist, see

* https://www.isdn4linux.de/mailman/listinfo/isdn4linux for details,

53
* Revision 1.126 2003/08/26 19:46:12 tobiasb
55
* - Added support for AVM B1 (with layer 2 d-channel trace) in point-to-
56
* point mode, where only TEI 0 is used ("Anlagenanschluss" in German).
57
* Many thanks to Klaus Heske for his testing efforts.
58
* - The source number "0" in outgoing calls is now expanded to
59
* +<country><area>0. This may be useful for point-to-point setups,
60
* when <area> contains area code and local number without extension.
61
* - Basic support for different codesets in (E)DSS1 messages. Except
62
* for codeset 0, unknown information elements are now silently
63
* ignored (controlled by ignore_unknown_IE in isdnlog/isdnlog.h).
64
* - Added some information elements to isdnlog/messages.c.
65
* - Increased the length of msn (local number) in struct telnum.
66
* - Fixed seperation of country and area code for long numbers
67
* in getDest, tools/dest.c.
68
* - Changed broken (with gcc 2.95.2) generation of .depend. The old
69
* output did not consider the location of objectfiles in subdirs.
70
* Remove this file before compiling this upgraded isdnlog.
71
* - Moved DUALFIX... defines from tools/tools.h to isdnlog/isdnlog.h.
72
* - Added missing R:-Links for cellphone entries in country-de.dat.
73
* - Different entry for each city "Neustadt" in tools/zone/de/code.
74
* - Earlier changes since isdnlog-4.65:
75
* - Allow dualmode workaround 0x100 (DUALFIX_DESTNUM) to work also with
76
* CALL_PROCEEDING messages for cleaning up unanswered incoming calls.
78
* Revision 1.125 2003/08/14 12:18:57 tobiasb
79
* Allow dualmode workaround 0x100 aka DUALFIX_DESTNUM to work also with
80
* CALL_PROCEEDING messages for cleaning up unanswered incoming calls.
81
* (http://lists.suse.com/archive/suse-isdn/2003-Aug/0026.html in German)
82
* Update for `Denmark cellphone' entry in destination database.
84
* Revision 1.124 2003/07/25 22:18:03 tobiasb
86
* - New values for isdnlog option -2x / dual=x with enable certain
87
* workarounds for correct logging in dualmode in case of prior
88
* errors. See `man isdnlog' and isdnlog/processor.c for details.
89
* - New isdnlog option -U2 / ignoreCOLP=2 for displaying ignored
91
* - Improved handling of incomplete D-channel frames.
92
* - Increased length of number aliases shown immediately by isdnlog.
93
* Now 127 instead of 32 chars are possible. (Patch by Jochen Erwied.)
94
* - The zone number for an outgoing call as defined in the rate-file
95
* is written to the logfile again and used by isdnrep
96
* - Improved zone summary of isdnrep. Now the real zone numbers as
97
* defined in the rate-file are shown. The zone number is taken
98
* from the logfile as mentioned before or computed from the current
99
* rate-file. Missmatches are indicated with the chars ~,+ and *,
100
* isdnrep -v ... explains the meanings.
101
* - Fixed provider summary of isdnrep. Calls should no longer be
102
* treated wrongly as done via the default (preselected) provider.
103
* - Fixed the -pmx command line option of isdnrep, where x is the xth
105
* - `make install' restarts isdnlog after installing the data files.
106
* - A new version number generates new binaries.
107
* - `make clean' removes isdnlog/isdnlog/ilp.o when called with ILP=1.

/* Tobias Becker, 2003-02-25:
4884
Using dualmode and a HFC card, an outgoing call from an a/b adapter
4885
(labelled `1&1', dating from 1996) produced the following messages
4886
recognized by isdnlog:
4887
(1) NET -> SETUP ACK.. with CHANNEL: BRI, B1 needed
4888
(2) USR -> SETUP with BEARER, CHANNEL: any channel, and Calling
4890
No further CHANNEL messages occur for this call. Prior to (1)
4891
there may be lost messages as isdnctrl0 states:
4892
`03:09.16 Card1 empty_fifo hfcpci paket inv. len 2 or crc 255'
4893
(1) is decoded in chan 5, sets channel=1 and triggers the move
4894
from chan 5 to chan 0.
4895
(2) is decoded in chan 5 (SETUP overrides chan 0 before) but
4896
does not set channel, so the information in call[5] is not
4898
Work-around: decode SETUP in chan 0/1 when cref match
4899
This workaround requires the value of DUALFIX_SRCNUM in dualfix,
4900
which is set with -2.. or dual=.. at command line or parameter file.
