/* History
Old Log (for new changes see ChangeLog):
Revision 1.5 2003/04/17 10:39:42 gernot
- support ALERTING notification (to know when it's ringing on the other side)
- cosmetical fixes in capi.cpp
Revision 1.4 2003/04/04 09:14:02 gernot
- setListenTelephony() and setListenFaxG3 now check if the given controller
supports this service and throw an error otherwise
Revision 1.3 2003/04/03 21:16:03 gernot
- added new readProfile() which stores controller profiles in attributes
- getInfo() only creates the string out of the stored values and doesn't
do the real inquiry any more
- getInfo() and numControllers aren't static any more
Revision 1.2 2003/02/21 23:21:44 gernot
- follow some a little bit stricter rules of gcc-2.95.3
Revision 1.1.1.1 2003/02/19 08:19:53 gernot
initial checkin of 0.4
Revision 1.28 2003/02/10 14:20:52 ghillie
merged from NATIVE_PTHREADS to HEAD
Revision 1.27.2.1 2003/02/09 15:05:36 ghillie
- rewritten to use native pthread_* calls instead of CommonC++ Thread
Revision 1.27 2003/01/19 16:50:27 ghillie
- removed severity in exceptions. No FATAL-automatic-exit any more.
Removed many FATAL conditions, other ones are exiting now by themselves
Revision 1.26 2003/01/06 16:29:25 ghillie
- added debug output for constructor/destructor
- added call to terminate() in destructor
- missing break added in readMessage (oops... :-|)
- consider CapiReceiveQueueEmpty as error in readMessage()
- support finishing in run()
- only call readMessage() when waitformessage returned CapiNoError
Revision 1.25 2003/01/04 16:07:42 ghillie
- log improvements: log_level, timestamp
Revision 1.24 2002/12/18 14:40:23 ghillie
- removed this nasty listen_state. It had no sense than making problems.
- small change in getInfo()
- added check for abilities in setListen* if you say 0 for all controllers.
Do nothing if this ability isn't provided for this controller
Revision 1.23 2002/12/13 09:57:10 ghillie
- error message formatting done by exception classes now
Revision 1.22 2002/12/09 15:32:58 ghillie
- debug stream now given in constructor
- debug output improvements
- exception cleanup (removed WARNING exceptions, output messages, ...)
Revision 1.21 2002/12/06 12:55:28 ghillie
- don't delete Connection objects any more
Revision 1.20 2002/12/05 15:00:06 ghillie
- new methods registerApplicationInterface(), unregisterConnection()
- use debug stream given in constructor, not from ApplicationInterface any more
- connect_req gets Connection* now, enters it with pseudoPLCI in connections map
- readMessage(): when receiving CONNECT_CONF: searches for pseudoPLCI in connections and moves this entry to real plci
- readMessage(): when receiving DISCONNECT_INF: don't erase Connection object from connections map, this will be done in Connection::~Connection
Revision 1.19 2002/12/02 16:53:51 ghillie
- minor debug output change
Revision 1.18 2002/11/29 11:11:12 ghillie
- moved communication thread from own class (CapiCommThread) to Capi class
Revision 1.17 2002/11/29 10:22:19 ghillie
- updated comments, use doxygen format now
- fixed small typo in setListen* methods
Revision 1.16 2002/11/27 15:58:52 ghillie
caught exceptions from disconnect_ind()
Revision 1.15 2002/11/25 20:57:21 ghillie
setListen* methods can now set listen state on all found controllers
Revision 1.14 2002/11/22 15:08:22 ghillie
- new method select_b_protocol_req()
- added SELECT_B_PROTOCOL_CONF case in readMessage()
Revision 1.13 2002/11/19 15:57:18 ghillie
- Added missing throw() declarations
- phew. Added error handling. All exceptions are caught now.
Revision 1.12 2002/11/18 14:24:09 ghillie
- moved global severity_t to CapiError::severity_t
- added throw() declarations
Revision 1.11 2002/11/17 14:38:34 ghillie
- improved exception throwing: using different exception types with severity parameter (FATAL,ERROR,WARNING) now
- changed getInfo() to use macros from /usr/include/capiutils.h now
Revision 1.10 2002/11/15 15:25:53 ghillie
added ALERT_REQ so we don't loose a call when we wait before connection establishment
Revision 1.9 2002/11/15 13:49:10 ghillie
fix: callmodule wasn't aborted when call was only connected/disconnected physically
Revision 1.8 2002/11/13 08:34:54 ghillie
moved history to the bottom
Revision 1.7 2002/11/10 17:04:21 ghillie
improved some debug output
Revision 1.6 2002/11/08 07:57:07 ghillie
added functions to initiate a call
corrected FACILITY calls to use PLCI instead of NCCI in DTMF processing as told by Mr. Ortmann on comp.dcom.isdn.capi
Revision 1.5 2002/10/31 15:39:04 ghillie
added missing FACILITY_RESP message (oops...)
Revision 1.4 2002/10/31 12:37:34 ghillie
added DTMF support
Revision 1.3 2002/10/29 15:42:29 ghillie
typos...
Revision 1.2 2002/10/29 14:09:12 ghillie

cosmetic fixes
Revision 1.1 2002/10/25 13:29:38 ghillie
grouped files into subdirectories
Revision 1.12 2002/10/09 11:18:59 gernot

Revision 1.11 2002/10/05 20:43:32 gernot
quick'n'dirty, but WORKS
Revision 1.10 2002/10/05 13:53:00 gernot

reactivated error handling for Capi::getInfo()
Revision 1.8 2002/10/04 15:48:03 gernot
structure changes completed & compiles now!
Revision 1.7 2002/10/04 13:27:15 gernot
