 * This section describes functions to initialize and register G.711 codec
 * factory to the codec manager. After the codec factory has been registered,
 * application can use @ref PJMEDIA_CODEC API to manipulate the codec.
 *
 * The G.711 is an ultra low complexity codecs and in trade-off it results
 * in high bitrate, i.e: 64kbps for 16-bit PCM with sampling rate 8000Hz.
 *
 * The factory contains two main compression algorithms, PCMU/u-Law and 
 * PCMA/A-Law.
