+ * The use of the jitterbuffer *
+ *******************************
+ * Always create a new jitterbuffer with jb_new().
+ * Always destroy a jitterbuffer with jb_destroy().
+ *
+ * There is no lock(mutex) mechanism, that your responsibility.
+ * The reason for this is that different environments require
+ * different ways of implementing a lock.
+ *
+ * The following functions require a lock on the jitterbuffer:
+ * jb_reset(), jb_reset_all(), jb_destroy(), jb_set_settings(),
+ * jb_get_info(), jb_get_settings(), jb_has_frames(), jb_put(),
+ * jb_get()
+ *
+ * The following functions do NOT require a lock on the jitterbuffer:
+ * jb_new(), jb_guess_mos()
+ *
+ * Since control packets have a higher priority above any other packet
+ * a call may already be ended while there is audio left to play. We
+ * advice that you poll the jitterbuffer if there are frames left.
+ *
+ * If the audiopath is oneway (eg. voicemailbox) and the latency doesn't
+ * matter, we advice to set a minimum jitterbuffer size. Then there is
+ * less loss and the quality is better.

+specified bit rates - 64000bps, 56000bps and 48000bps. It passes the ITU tests.
+
+To allow fast and flexible interworking with narrow band telephony, the encoder and decoder
+support an option for the linear audio to be an 8k samples/second stream. In this mode the
+codec is considerably faster, and still fully compatible with wideband terminals using G.722.
