 *
 * Revision 1.26  2002/11/13 10:13:16  rogerh
 * Add Speex codec.
 *
 * Revision 1.25  2002/11/10 08:10:43  robertj
 * Moved constants for "well known" ports to better place (OPAL change).
 *
 * Revision 1.24  2002/11/10 04:26:55  robertj
 * Fixed setting of jitter paramters
 *
 * Revision 1.23  2002/11/04 10:27:48  rogerh
 * Only print duration when a connection was made. (copied from ohphone)
 *
 * Revision 1.22  2002/10/31 00:52:18  robertj
 * Enhanced jitter buffer system so operates dynamically between minimum and
 *   maximum values. Altered API to assure app writers note the change!
 *
 * Revision 1.21  2002/07/17 05:52:21  robertj
 * Fixed using -i parameter for interface when discovering gk, thanks Steve Frare
 *
 * Revision 1.20  2002/02/11 06:20:07  robertj
 * Moved version.h to root directory so have one for the library and not just
 *   the sample application. SimpH323 uses the library version so they remain
 *   in sync.
 *
 * Revision 1.19  2001/11/01 01:35:25  robertj
 * Added default Fast Start disabled and H.245 tunneling disable flags
 *   to the endpoint instance.

 *
 * Revision 1.16  2001/08/24 13:34:40  rogerh

 *
 * Revision 1.15  2001/08/10 10:06:50  robertj
 * No longer need SSL to have H.235 security.
 *
 * Revision 1.14  2001/08/06 03:18:35  robertj
 * Fission of h323.h to h323ep.h & h323con.h, h323.h now just includes files.
 * Improved access to H.235 secure RAS functionality.
 * Changes to H.323 secure RAS contexts to help use with gk server.
 *
 * Revision 1.13  2001/08/03 11:56:26  robertj
 * Added conditional compile for H.235 stuff.
 *
 * Revision 1.12  2001/07/13 08:44:16  robertj
 * Fixed incorrect inclusion of hardware codec capabilities.
 *
 * Revision 1.11  2001/05/17 07:11:29  robertj
 * Added more call end types for common transport failure modes.
 *
 * Revision 1.10  2001/05/14 05:56:26  robertj
 * Added H323 capability registration system so can add capabilities by
 *   string name instead of having to instantiate explicit classes.
 *
 * Revision 1.9  2001/03/21 04:52:40  robertj
 * Added H.235 security to gatekeepers, thanks F黵bass Franz!
 *
 * Revision 1.8  2001/03/20 23:42:55  robertj
 * Used the new PTrace::Initialise function for starting trace code.
 *
 * Revision 1.7  2000/10/16 08:49:31  robertj
 * Added single function to add all UserInput capability types.
 *
 * Revision 1.6  2000/07/31 14:08:09  robertj
 * Added fast start and H.245 tunneling flags to the H323Connection constructor so can
 *    disabled these features in easier manner to overriding virtuals.
 *
 * Revision 1.5  2000/06/20 02:38:27  robertj
 * Changed H323TransportAddress to default to IP.
 *
 * Revision 1.4  2000/06/07 05:47:55  robertj
 * Added call forwarding.
 *
 * Revision 1.3  2000/05/23 11:32:27  robertj
 * Rewrite of capability table to combine 2 structures into one and move functionality into that class
 *    allowing some normalisation of usage across several applications.
 * Changed H323Connection so gets a copy of capabilities instead of using endponts, allows adjustments
 *    to be done depending on the remote client application.
 *
 * Revision 1.2  2000/05/11 10:00:02  robertj
 * Fixed setting and resetting of current call token variable.
 *
 * Revision 1.1  2000/05/11 04:05:57  robertj
