+   * @brief Implementation of BCG729 codecs.
+   * @{
+   *
+   * This section describes functions to initialize and register BCG729 codec
+   * factory to the codec manager. After the codec factory has been registered,
+   * application can use @ref PJMEDIA_CODEC API to manipulate the codec.
+   *
+   * This codec factory contains G.729 codec.
+   *
+   * \section pjmedia_codec_bcg729 BCG729
+   *
+   * BCG729 is compliant with ITU-T G.729 and Annexes A, B specifications.
+   *
+   * BCGG729 supports 16-bit PCM audio signal with sampling rate 8000Hz,
+   * frame length 10ms, and resulting in bitrate 8000bps.
+   *
+   * \subsection codec_setting Codec Settings
+   *
+   * General codec settings for this codec such as VAD and PLC can be
+   * manipulated through the <tt>setting</tt> field in #pjmedia_codec_param.
+   * Please see the documentation of #pjmedia_codec_param for more info.
+   *
+   * Note that G.729 VAD status should be signalled in SDP, see more
+   * description below.
+   *
+   * \subsubsection annexb Annex B
+   *
+   * The capability of VAD/DTX is specified in Annex B.
+   *
+   * By default, Annex B is enabled. This default setting of Annex B can
+   * be modified using #pjmedia_codec_mgr_set_default_param().
+   *
+   * In #pjmedia_codec_param, Annex B is configured via VAD setting and
+   * format parameter "annexb" in the SDP "a=fmtp" attribute in
+   * decoding fmtp field. Valid values are "yes" and "no",
+   * the implementation default is "yes". When this parameter is omitted
+   * in the SDP, the value will be "yes" (RFC 4856 Section 2.1.9).
+   *
+   * Here is an example of modifying default setting of Annex B to
+   * be disabled using #pjmedia_codec_mgr_set_default_param():
+   \code
+      pjmedia_codec_param param;
+
+      pjmedia_codec_mgr_get_default_param(.., &param);
+      ...
+      // Set VAD
+      param.setting.vad = 0;
+      // Set SDP format parameter
+      param.setting.dec_fmtp.cnt = 1;
+      param.setting.dec_fmtp.param[0].name = pj_str("annexb");
+      param.setting.dec_fmtp.param[0].val  = pj_str("no");
+      ...
+      pjmedia_codec_mgr_set_default_param(.., &param);
+   \endcode
+   *
+   * \note
+   * The difference of Annex B status in SDP offer/answer may be considered as
+   * incompatible codec in SDP negotiation.
