 * Revision 1.4  2003/01/07 07:53:00  craigs
 * Fixed problem with multi-frame G.723.1 packets
 *
 * Revision 1.3  2002/09/16 01:14:15  robertj
 * Added #define so can select if #pragma interface/implementation is used on
 *   platform basis (eg MacOS) rather than compiler, thanks Robert Monaghan.
 *
 * Revision 1.2  2002/05/23 04:22:29  robertj
 * Fixed problem with detecting correct payload type. Must
 *   wait for first non-empty packet.
