* OpalMediaFormat instances are initialised before use.
*
* Revision 2.8 2004/02/23 01:32:06 rjongbloed
* Removed duplicate #if for if voice age included and made sure there was a
* dummy G729 declaration macro if no G.729 included.
*
* Revision 2.7 2004/02/19 10:46:43 rjongbloed
* Merged OpenH323 version 1.13.1 changes.

* Updated to OpenH323 v1.10.3
*
* Revision 2.3 2002/09/16 02:52:33 robertj
* Added #define so can select if #pragma interface/implementation is used on
* platform basis (eg MacOS) rather than compiler, thanks Robert Monaghan.
*
* Revision 2.2 2002/09/04 06:01:46 robertj
* Updated to OpenH323 v1.9.6
