*
* \ingroup channel_drivers
+ *
+ * \note Since this works with any audio system that libportaudio supports,
+ * including ALSA and OSS, this may someday deprecate chan_alsa and chan_oss.
+ * However, before that can be done, it needs to *at least* have all of the
+ * features that these other channel drivers have. The features implemented
+ * in at least one of the other console channel drivers that are not yet
+ * implemented here are:
+ *
+ * Multiple device support
+ * Set Auto-answer from the dialplan
+ *
+ * answer CLI command
+ * flash CLI command
+ * transfer CLI command
+ * autoanswer CLI command (maybe general settings CLIcommand, instead?)
+ * boost CLI command
+ * active CLI command
